CAUTION: Caution statements signal the user about hazards or unsafe practices which could result in minor personal injury or product or property damage. WARNING: Warning statements signal the user about hazards or unsafe practices which could result in severe personal injury or death.

(1) To safeguard against damage during transit, transport your Smart Ultra OVAL to the installation site in the same container used for transportation from the factory if circumstances permit. (2) Smart Ultra OVAL is adjusted and inspected as an assembly consisting of the meter body, sensor and register. It should therefore be handled as an integral assembly. (3) The register is accurately configured and adjusted. Do not attempt to remove the front cover to gain access to its internal assembly. 1.3 Storage Considerations If your Smart Ultra OVAL is stored for long periods of time upon receipt before installation, unexpected faulty conditions could result. If a long-term storage is anticipated, take the following precautions: (1) Keep your Smart Ultra OVAL in store in the same shipping container used for transportation from OVAL if possible. (2) Place of storage should conform to the following requirements: - Free from rain and water. - Free from vibration and impact shocks. - Temperature and relative humidity in the storage place are at or near room temperature and humidity (around 25°C and 65%). (3) Purge the Smart Ultra OVAL that has once been placed in service with clean air, N2 gas, etc. to prevent the metered fluid from adhering to the meter connections, piping inner walls, housing, etc. before storage. (Wash clean with suitable detergent if necessary.) (4) In case of storage for extended periods of time, good practice is to keep in store in the same containers used for shipment from the factory. 1.1 Confirming the Tag Every Smart Ultra OVAL is assembled and adjusted according to individual specifications. Product code number and ratings are stated on the register tag. Make sure that, by referring to the general specifications on pages 28 and the product code explanation on page 29, the ratings shown conform to your particular specification. 1. BEFORE YOU BEGIN Every Smart Ultra OVAL is thoroughly tested before it leaves the factory. When received, it should be thoroughly inspected for indication of rough handling during transit. Necessary handling precautions are described in this section; read the instructions carefully. As for other information, find the respective sections from "CONTENTS" on pages 2. For any inquiries, contact your nearest OVAL designated sales office. CAUTION: When you make inquiries, include the product name, model number, product number, ratings and other pertinent information. NAMEPLATE (RATINGS SHOWN)

(1) The register is of waterproof construction for outdoor service. (2) The register is type approved. Do not attempt to replace component parts with others or make any circuit modification. (3) The pressuretight packing furnished constitutes part of the flameproof construction. Do not attempt to use any pressuretight packing other than those furnished. The pressuretight packing union should be tightened securely upon completion of connections. (4) Of the four different pressuretight packings (φ9, φ10, φ11 and φ12) furnished as standard accessories, a φ11 packing is tentatively installed in place. Select from these and install the one that best fits the finished outside diameter of your particular cable. Table 1.1 Applicable Cable Outside Dia. Unit in mm Packing Code Packing I.D.

Precautions on cable lead-in fitting (pressuretight packing), both explosionproof and non-explosionproof models: - Use a pressuretight packing that fits the finished cable O.D. - Tighten up properly to allow no clearance between the pressuretight packing and the cable. - If a pressuretight packing is not used, apply some waterproof treatment to preclude any chance of moisture getting into the equipment. 2. OPERATING CONDITIONS To maintain the stated high accuracy and long service life of SMART ULTRA OVAL flowmeter, make sure that flowrate, pressure, temperature and viscosity are within the ratings as stamped on the meter register nameplate. Do not fail to confirm these ratings before placing it in service. CAUTION 1. Although allowable ambient temperature is up to +60 °C for explosionproof units, it is desirable that the meter be used at room temperature and humidity. 2. In cases where the register is exposed to elevated temperatures due to exposure to direct rays of the sun or to radiant heat, ensure, by providing a sunshade or similar protection, that the meter is used within the operating temperature range. NOTE: Avoid such installation locations where 1. Not easy to access for servicing. 2. Large temperature variation and vibration. 3. Potential risk of submersion in water. 4. Corrosive gas atmosphere. 5. Not compatible with ex. construction. 6. Near sources of strong magnetic noises.

Smart Ultra OVAL has been developed to meet the needs of precise flowrate measurement. The local direct- reading total counter is an all-electronic register built around a single-chip CPU. With the latest electronic technologies used throughout, this versatile register displays accumulated total flow, instantaneous flowrate (digital readout) and provides, by option, a pulse and analog output proportional to the rate of flow. In this meter, fluid flow is detected by sensing with an amorphous sensor the magnetic fields of permanent magnets embedded in the oval rotors. As a result, high reliability is achieved. Features (1) Absence of any mechanically sliding components except for oval rotors contributes to long service life. (2) Small wetted parts count and pocketless design makes this meter ideally suited for flow measurement of chemical liquids. (3) You can monitor accumulated total flow and instantaneous flowrate locally on the digital display. (4) When coupled with a remotely located receiving instrument, output signals can readily and simply be used for applications including control, adjustment and recording. (5) IEC explosionproof construction offers increased safety and the design is compact. (6) A nonvolatile memory, both in the local totalizer type and externally powered type meters, retains accumulated total in the event of power failure or when de-energized. NOTE: With the use over an extended period of time, meter error will deviate more or less from the initial point. Upon request, we may conduct an instrumental error testing once again and establish a "new meter factor" in the scaler when your Smart Ultra OVAL is returned to the factory for periodic inspection or for other reasons. If you have any request, contact the supplier you purchased the product or our sales office. 4.

5.1 About "MODE" Switch Removing the selector magnet inserted at the bottom of the register, apply it to the label "MODE" on the LCD counter face and the display will scroll forward through the available readings as shown in Fig. 5.1. CAUTION Do not fail to return the selector magnet to its holder after use lest you will not lose it. It uses an intensive magnet; never hold it close to floppy disks or other magnetic storage media. 5.2 Display Functions The display can show four different kinds of flow information - total flow, instantaneous actual flowrate, percent instantaneous flowrate, and 8-division percent bar graph. It also shows the following error messages: Full scale exceeded : ErrorFS Upper-limit flowrate exceeded : ErrorOF NOTE: Multiple errors will be indicated in priority order below: ErrorOF > ErrorFS 5.3 Display Mode Selection Two ways are available to select displays - with a display select switch inside the register, or through communications with the Smart Communication Unit Model EL2310 (or HHC: Model EK10). If your option is through communications, follow the instructions outlined in the Smart Communication Unit EL2310 (or HHC: EK10) instruction manual. NOTE: Show "Measure" window at "View" menu on the PC screen. Selection with display select switch requires access to the display select switch SW1 by opening the register cover facing its internal assembly and pressing this switch (see page 20). The display scrolls forward through available information each time you press this switch as shown in Fig. 5.1.

Displayed total flow can be reset either by the display select switch SW1 (see Fig. 11.1 on page 20) or through communications with the Smart Communication Unit. It your option is through communications, follow the instructions outlined in the Smart Communication Unit EL2310 (or HHC: EK10) instruction manual. NOTE: Show "Measure" window at "View" menu on the PC screen. With the display select switch, then, you can reset the totalizer by holding the display select switch SW1 depressed for more than 3 seconds while the total flow is shown. 5.5 Considerations with Pulse Output Type (1) If your model is of pulse output type, the pulse output and total counter remain inoperative for 15 seconds approx. after power on and while communications with the Smart Communication Unit continue. For 15 seconds approx. after termination of communications, the pulse output and total counter also remain inoperative. (2) Requirements for validating communications Communications are made valid only when the following requirements are met: - Flowrate at zero (There is no pulse output.) - Within 15 seconds after power turn-on NOTE: The period of 15 seconds immediately after power on is called "Communication standby mode." (The built-in indicator, if so equipped, will display as shown in ① in the figure below.) If communications are started during this time period, a switchover to "Communication mode" takes place, permitting you to communicate until power is turned off the next time. (The built-in indicator will display as shown in ② in the figure below.) To start flow measurement routine, turn power on again. (After power cycling, the pulse output and total counter will also remain inoperative for 15 seconds.) (3) While communications continue, the receiving instrument (total counter, etc.) may overcount under certain circumstances. To eliminate the possibility of such erratic extra counting, precautions should be taken by either disconnecting the receiving instrument before starting communications, or recording the most recent total reading and other important data on paper. (4) Except for the purpose of communications, do not attempt to connect the probe of Smart Communication Unit with the signal lines. If the probe remains connected, the influence of capacitive impedance the interface has could go to the point of producing distorted signals in waveform and, as a result, the receiving instrument would fail to receive pulse signals accurately. CAUTION: PRECAUTIONS with ANALOG OUTPUT TYPE The analog type permits communications with the Smart Communication Unit at any time. However, if, in an attempt to alter current parameters, the meter is configured by mistake such that the new parameters are incompatible with the specification, resultant sharp changes in output may disturb the behavior of the receiving instrument. It is good practice, therefore, to make parameter changes while the fluid flow is at zero. ② ① 15 seconds after power on. (Com Standby Mode) Communication is started within 15 seconds after power on.

(1) Flush the piping assembly. Flushing must be performed before meter installation. Install a short pipe in place of the meter at this time (see diagram below). BYPASS LINE STRAINER VALVE SHORT PIPE FLOW DIRECTION (1) In case flow direction is from R to L, switch the places of meter and strainer. (2) Arrange piping so as to facilitate drainage. (3) S t r a i n e r s h o u l d b e inspected on a regular basis. 6.3 Standard Installation, Vertical Line (1) If the flow direction is from top to bottom, switch the places of meter and strainer. (2) Installing the strainer at "A" will make net reinstallation difficult at cleaning; we recommend to install the strainer at "B". 6.4 Example of Faulty Piping NOTE: For outline dimensions and pipe connection dimensions, see approval drawing. OUT IN A B Marked * is the space required for disassembly and inspection. BYPASS STRAINER ULTRA OVAL OUT IN *(1100mm) WRONG! OUT IN (2) Install the meter free from pipe strains. (3) The meter must be installed on the discharge side of the pump. (4) If the meter is to be used under tank head, give a head pressure greater than the losses with the piping system, strainer, meter, etc. NOTE: Pressure losses of the Smart Ultra OVAL and strainers are stated in the GENERAL SPECIFICATIONS. (5) The meter installation is correct if the flow direction conforms to the arrow mark on the meter body. (6) The strainer should be located upstream of, and as close to the meter as possible. (7) Since the sensor in the Smart Ultra OVAL operates on the principle of sensing changes in magnetic flux density, it must be isolated from the influence of any external magnetic flux. In order to minimize the influence of external magnetic flux, select an installation location at least 5 meters away from existing power equipment and conductors - potential sources of creating strong magnetic and electric fields, such as motors and generators. (8) In case electric heating is desired, consult the factory. (9) In the heat retention work, aviod covering up the fins and heating tube with lagging material. - Typical Smart Ultra OVAL Installations 6.2 Standard Installation, Horizontal Line Do not install the meter in a position like this. "See also page 15 for the jacketed type".

CAUTION: Do not fail to turn power OFF if the meter is of remote output type. To reverse the flow direction, change the orientation of both the register and flowmeter body to the new flow direction. (1) Take off four hex socket head screws (M6) with hex wrench. CAUTION 1. Rotate the register assembly without separating it from the skirt. 2. Do not attempt to rotate the register assembly more than one complete revolution. (2) Holding the register assembly in both hands, carefully rotate it and then secure it with hex socket head screws in line with the new direction of flow. Size 50 Sizes 52, 53, 55, 56, 57 REGETER ASSEMBLY CAREFULLY ROTATE. SKIRT Don’t separate! Do not attempt to change flow directions by separating the register assembly like this. NOTE: If you have separated the register assembly, first return it to the state before changing the flow direction, then follow the correct procedure in step (2) (without separating the register assembly) again to change flow directions.

8.1 Wiring Guidelines (1) Cables for field wiring The following cables should be used unless otherwise specified: Use cables of conductor area 1.25mm2 and finished O.D. 12mm, selecting from 2 to 4pcs. according to your application. It is recommended that their shield be grounded at the receiving instrument. CAUTION: In case of TIIS explosionproof type used under the ambient temperature of 50°C or higher, use a cable resistant to the temperature of 70°C or higher. (2) Transmission length The maximum transmission length is typically one kilometer. NOTE: If it exceeds one kilometer, consult us. (3) Inductive interference prevention To minimize the possibility of stray current pickup, the field wiring should be routed sufficiently away from existing power cables or power circuits. (4) Considerations on connections 1) M3.5 terminal posts are used on the terminal block. Use crimp-style terminals that fit the conductors at the cable end. 2) Be sure to earth ground the preamplifier's ground terminal. 3) Pitch down the cable from the cable entry so that rainwater will not have a chance to enter the equipment through the cable. 4) In areas where lightning strokes are expected, provide a lightning arrestor for protection. CAUTION: Make sure of the validity of meter (register) and receiving instrument combination by referring to their model numbers, serial numbers, etc. before you make electrical connections. 8.2 Terminal Connections (1) Take off four hex socket head bolts (402) on the front of register assembly and remove the cover (401). (2) Remove the cover to gain access to a 4-post terminal block. Terminal identification is found on the back of cover. (3) Using crimped-lug terminals, ensure good electrical connections. HEX WRENCH COVER HEX SOCKET HEAD BOLTS O-RING REMOTE OUTPUT TERMINALS EXTERNAL GROUND TERMINAL INTERNAL GROUND TERMINAL NOTE: 1. Pressuretight packing is not furnished with non- explosionproof models and non-output models (see page 5). 2. Connect the external earth ground terminal to instrumentation earth ground before use. (Refer also to the wiring instructions of respective receiving instrument instruction manual.)

The 2-wire signal transmission system used in this flowmeter furnishes DC power to the meter. It serves as the power line and signal line as well with pulse or analog current output. An OVAL receiving instrument can be coupled directly, but instruments in general which are designed to accept a voltage signal input require a load resistor RL connected in series for voltage conversion. Since the voltage signal level varies with the load resistance value, determine the load resistance value by referring to the receiving instrument specifications and the acceptable load resistance range shown below. Communications with a PC (Smart Communication Unit) requires a 250 to 1000Ω load. ● In case a voltage input is fed to the receiving instrument Output Voltage Signal (V) Pulse Output ON/OFF = (20mA × RL) / (4mA × RL) Analog Output (4mA × RL) − (20mA × RL) at 0 ro FS NOTE: With the relationship with supply voltage E, select the load resistance value R L such that the current flowing into the transistor is held below 50mA.

9.1 Operation At first-time operation, carefully operate in the following sequence, allowing the flow within the flow range specified. (Refer to the piping diagram below.) (1) Shut off the valve (A) on the inlet side and the valve (B) on the outlet side and then open the bypass line valve (C) to allow the fluid in the bypass line, thereby removing weld chips, scales and other foreign matter left in the piping assembly. CAUTION: This is particularly important on new installations. (2) Carefully and slightly at first, open the valve (A) upstream of the meter progressively and then, slightly at first, open the valve (B) downstream progressively. (3) Slowly close the bypass line valve (C) and make sure that the total counter in the register advances in response. Maintain a flowrate 10 to 20% of the maximum flowrate (confirm it in the instantaneous flowrate display mode) at this time, allow the flow for more than 15 minutes and make sure that air in the piping assembly has totally escaped. In applications where temperature exceeds 60°C, run the system at least for 30 minutes in this state to ensure uniform heat distribution in the measuring chamber. (4) Following the break-in operation (preheating), shut off the bypass line valve (C) completely and open the upstream valve (A) progressively until fully open and slowly open the downstream valve (B) until the rated flow is obtained. (5) Flowrate should be regulated with the valve (B) downstream of the meter and should be held within the rating. (6) The strainer net should be inspected for condition and cleaned on a regular basis. On a new installation, in particular, inspect daily first and, according to the clogged condition of the net being observed, inspection intervals may be reduced progressively to, say, once a week. Ａ Ｂ Ｃ BYPASS LINE METER STRAINER VALVE FLOW DIRECTION 9.2 Operating Precautions (1) When changing flowrates In applications where the flowrate varies or where shutoff valve opening and closure takes place in batch operation, avoid rapid changes in flowrate across the meter. Operating the meter at flowrates in excess of the maximum allowable flowrate will nullify the guaranteed accuracy, reduce the meter life and may result in faulty conditions, such as the seizure of bearings or the rotor-to-measuring chamber contact. (2) Where the temperature of metered fluid changes Avoid rapid temperature changes in the meter. Temperature changes of the fluid in the meter should be held within 3°C per minute. Extra care should be used particularly when making a flow measurement in batch operation without the provision of heat tracing of the piping where the fluid temperature differs from atmospheric temperature. If rapid temperature changes are anticipated, heat trace the piping assembly as well as the meter. EXCESSIVE FLOW RAPID FLOW VARIATION RAPID TEMPERATURE CHANGES "See also page 15 for the jacketed type".

Temperature and pressure of LPG, polyvinyl chloride monomers or anything with low viscosity and low steam pressure that are too ready to vaporize should strictly be controlled. During operation, the temperature of bearings in the meter is usually higher than that of the metered fluid. Vapors around the bearings can be causes of faulty conditions, including generation of unusual noise and bearing seizure. (4) Corrosive liquids When you make a measurement of highly corrosive liquids, such as nitric acid and sulfuric acid, appropriate materials should be used for tanks and piping assembly. Heterogeneous materials originally contained in the metered fluid or corrosive substances liquated out from tanks and pipes of inappropriate materials may lead to costly downtime, as a result of locked rotors, for example, when they are allowed into the measuring chamber. CAUTION: If it is a jacketed model, see page 15. 9.3 Precautions at Operation Shutdown (1) Valves should be closed progressively. Rapid valve closure could, under certain piping conditions, cause a sharp pressure rise by water hammer, or hydraulic shock, resulting in damage to the meter. (2) Precautions against pressure buildup on closure Complete closure of valves upstream and downstream of the meter makes the affected section a totally enclosed chamber and could cause a rise of internal pressure due to a rise of atmospheric temperature, resulting in an unexpected damage to the meter. (3) Liquids ready to adhere or gel at zero flow velocity Liquids that tend to adhere and solidify or gel at flow velocities around zero must thoroughly be washed away from the meter interior by running cleaning fluid before shutdown. Negligence of this instruction may leave the meter as an immovable unit when the operator attempts to resume meter operation the next time. CAUTION 9.4 About Register Life Due to the life expectancy of components incorporated, such as the LCD and nonvolatile memory, the internal electronics are designed to be replaced in about 10 years. The electronics life depends on the environment in which they are used; if any of the following operating conditions applies, we recommend you to replace them an assembly in five to six years: - High temperature environment. - High temperature process fluid measurement. - Field installation with widely varying temperatures. - LCD counter display is directly exposed to the rays of the sun (ultraviolet rays). - Frequent process fluid flow interruptions. TAKE PRECAUTIONS AGAINST BEARING SEIZURE!

Hot water or steam jacketed meters require piping work in the following manner: (1) Piping to the meter body remains the same as that of standard meters (meters not jacketed). (2) Adhere to the following instructions for the piping to the jacket: Steam Jacketed Basically, the piping should be so arranged that steam flows in from the top and out from the bottom. Provide steam traps at outlet ports (see figure below). ⇩ Hot-water Jacketed Basically, the piping should be so arranged that hot water flows in from the top and out from the top (see figure below).⇩ (3) Although the measuring chamber is heat treated, due consideration should be taken not to give piping elongation or contraction by sharp temperature changes or pipe strains. Progressive heating is suggested at least four hours before commencing service operation. (4) As for outline dimensions and tubing connection dimensions, see approval drawings. (5) If heat tracing is desired, considerations should be taken to facilitate maintenance and servicing. Make sure, if it is the case, that there is no liquid leaks when related components are covered with lagging material. (6) Lagging should be so provided that the top cover of strainer is easily accessible. Also it is necessary that the strainer net be cleaned on a regular basis. (7) Never attempt to lag radiator fins. Lagging them will cause excessive heat buildup in the register and pulse generator, possibly leading to costly downtime. NOTE: As for outline dimensions and tube connection dimensions, see approval drawing.

Although it depends on individual operating conditions, periodic disassembly and inspection should be performed at least once a year. CAUTION: Because Smart Ultra OVAL is a precision industrial instrument, disassembly and inspection should be performed indoors as a rule. If it is desired to disassemble and inspect it as installed in the field, an important precaution to remember is to reduce the internal pressure of the piping assembly to a safe level, shut off valves upstream and downstream of the meter fully, drain the piping assembly and then place a suitable fluid receptacle directly below the Smart Ultra OVAL. Exercise care to keep individual components disassembled free from grit and dust. CAUTION: Be sure to deenergize before you disassemble. ◆ Meter Body Inspection ◆ Complaint and possible cause: Process fluid will not run. Jammed with scales, the oval rotors fail to rotate, resulting in an interrupted fluid flow. 10.1 Size 50 Meter Body Disassembly and Inspection METER BODY HEX SOCKET HEAD BOLTS FRONT COVER O-RING HEX SOCKET HEAD BOLTS (2) With the front cover (register) removed, the measuring chamber with oval rotors and other components are now accessible. (1) Take off all six front cover fitting bolts (104) (M6), using wrench. With the bolts removed, the register integral with the front cover is ready to be separated from the meter body. Be careful not to drop the register front cover assembly. ROTOR SHAFTS ROTORS MEASURING CHAMBER (3) Remove oval rotors (201) from the measuring chamber and inspect them for condition. (a) Inspect the oval rotors to see if they are jammed with foreign solids. (b) Check the rotors, shafts and other members for wear. (c) Inspect the measuring chamber and the inner wall of front cover for damage or any other sign of unusual condition. Upon completion of these inspections, clean the oval rotors, rotor shafts, measuring chamber and front cover with clean water or suitable solvent thoroughly. CAUTION 1. Score marks, scratches, high spots due to impressions, or other flaws should be reconditioned flat with oil stone or other tool. 2. If the areas which have been in contact with rear cover jack bolts are distorted outwardly, recondition it flat with oil stone.

CAUTION: PRECAUTIONS BEFORE ASSEMBLY Oval rotors, inner walls of the rotor shafts, inner wall of the measuring chamber, inlet and outlet ports should be thoroughly washed clean, completely removing dust, grime and other foreign matter.

FRONT COVER O-RING HEX BOLTS (REGISTER SIDE) (3) Front Cover Installation Firstly install O-ring (108) on the front cover. If the O-ring is damaged or swollen with metered liquid, it will not fit in the groove. If such is the case, replace with a new one. Align the locating pin of front cover with its pin slot in the meter body and, fitting the rotor shafts into rotor shaft sockets in the front cover, force the meter body until the locating pin fits firmly in the pin slot in the meter body without slanting the front cover. Install six front cover fitting bolts (M6) and tighten them evenly until the front cover is closely in contact with the meter body. (4) Confirming Freely Rotation With air or water, make sure to see that the rotors move freely and that the register counts in response. CAUTION Rotation check should be performed at low rotor r.p.m. Violent rotor spinning may cause a damage to the components, such as bearing seizure. CAUTION: Since the registers are not compatible each other, do not replace one register with that of other meter.

CAUTION: Be sure to deenergize before you disassemble. REAR COVER (1) Take off all rear cover fitting bolts, using wrench. REAR COVER HEX BOLTS TOP COVER (2) Remove the rear cover to gain access to the top cover. (3) Using cross slot screwdriver, remove all four bolts securing the top cover in place. Then, use two of them to jack up the top cover, eventually to remove it. CAUTION When jacking the top cover off, turn the jacking screws evenly and alternately so that the top cover not slant. REAR COVER GASKET END PLATE (4) With the top cover removed, the measuring chamber with oval rotors and other components are now accessible. ROTOR SHAFT REAR COVER TOP COVER GASKET ROTORS (5) Remove oval rotors and rotor shafts, in this order, from the measuring chamber and inspect them for condition. (The rotor shafts should be drawn out straight.) (a) Make sure to see if the oval rotors are jammed with foreign matter. (b) Check to see if the rotors, shafts and other components are worn. (c) Inspect if the measuring chamber and inner wall of the front cover have any sign of scratches or other damage. Upon completion of these inspections, clean the oval rotors, rotor shafts, measuring chamber and front cover with cleans water or suitable solvent thoroughly. CAUTION 1. Score marks, scratches, high spots due to impressions, or other flaws should be reconditioned flat with oil stone or other tool. 2. If the areas which have been in contact with rear cover forcing bolts are distorted outwardly, recondition it flat with oil stone.

CAUTION: PRECAUTIONS BEFORE ASSEMBLY Oval rotors, inner walls of the rotor shafts, inner wall of the measuring chamber, inlet and outlet ports should be thoroughly washed clean, completely removing dust, grime and other foreign matter. NON TURN PIN ROTOR SHAFTS SHAFT SOCKET ROTORS 2ND ROTOR "2" MARKS 1ST ROTOR "1" MARKS FLOW IN OUT MATCH MARKS (2) Rotor Installation Rotor installation is correct if the side where signal generating magnets are embedded faces the register (bottom of the measuring chamber) and the sides with match marks ( • ) ( • • ) faces the rear cover. Carefully install the rotors with the 1st rotor (match mark " • ") on the shaft with "1" stamped on the outside of measuring chamber and the 2nd rotor (match mark " • •" ) on the shaft with "2" stamped. Ensure that the match marks are in alignment as shown in the inset. ROTORS TOP COVER (4) Installing top cover and confirming smooth rotor rotation With the locating pin of top cover in line with its pin slot in the meter body and fitting the rotor shafts into their sockets in the top cover, force them against the meter body until the locating pin fits in its slot in the meter body without slanting the top cover. Install top cover fitting bolts and tighten each of them evenly until the top cover is firmly in contact with the meter body. At this point, allowing air or water, make sure to see that the rotors move freely and that the register counts in response. CAUTION Rotation check should be performed at low rotor r.p.m. Violent rotor spinning may cause a damage to meter components, such as bearing seizure. REAR COVER GASKET (5) Rear Cover Installation Firstly install the gasket on the rear cover. If the gasket is found damaged, replace it with a new one. Install rear cover fitting bolts and tighten them evenly. NOTE: We suggest to replace the gasket with a new one at each disassembly. CAUTION: Since the registers are not compatible each other, do not replace one register with that of other meter. (1) Rotor Shaft Installation The non-turn pin end of each rotor shaft faces the register (bottom of the measuring chamber). Install the shafts, pin end first, into their sockets on the bottom of measuring chamber (bottom of meter body), forcing downward while turning each of them with hands until they are firmly installed in position. (Air in the sockets may resist to be compressed by the shafts. So good practice is to hold the shafts pressed down by hand for some time.) (3) Confirming the Rotor Gear Engagement Hand rotate the rotors to make sure of correct gear mesh. At this point, they may be shaky more or less as the shafts not fixed firmly. Exercise care not to damage the rotors and inner wall of the measuring chamber by forcing them to rotate.
