Temperature control units with more than 150 g natural refrigerant ▪ The temperature control unit has been constructed to the requirements of EU and EFTA coun- tries. ▪ Use the table as guidance for classifying the application field. Respect the max. refrigerant quanti- ty or the permissible highest quantity above ground level (GL) stated therein. ▪ For more information about the pre-installed gas detection sensor: - The built-in gas detection sensor enables a safety shutdown at 20% of the lower explosive limit via a power disconnect relay that is to be installed by the responsible body. The temperature control unit is thus switched off early and safely in case of fault. - A 24 V DC external power supply must be available for the pre-installed gas warning sen- sor. The alarm output of the gas warning sensor uses a 4 - 20 mA signal. Please refer to the data sheet of the gas warning sensor for further technical information. A separate pro- cessing unit is available as an accessory for the control of the power disconnect relay. The processing unit provides a potential-free switching contact and simultaneously provides the power supply and analysis of the gas warning sensor. Both variants require the respon- Classifying the applica- tion field

sheet of the gas warning sensor for the technical information necessary for the installa- tion. The alarm of the gas detection system can be connected to the responsible body’s alarm control unit. The responsible body is responsible for this and for the other measures. - The responsible body is responsible for the calibration of the gas detection sensor prior to initial operation and the observance of calibration and maintenance intervals according to the operation manual. We recommend to set calibration and maintenance intervals be- tween 6 and 12 months if no information is provided. For increased safety requirements, shorter intervals can be specified. On request we will recommend a specialist company to carry out the calibration and maintenance. 1.4.1.3 Temperature control units with fluorinated greenhouse gases/refrigerants F gases regulation (EC) No. 517/2014 of April 16, 2014, on fluorinated greenhouse gases, and re- pealing Regulation (EC) No. 842/2006. These regulations deal with all systems that contain fluorinated refrigerants. The substances dealt with in Directive (EC) No. 1005/2009 of the European Parliament and of the Council of 16 September 2009 that deplete the ozone layer are excluded (CFC/HCFC). The directive regulates the reduction of the emission, utilization, recovery, and destruction of cer- tain fluorinated greenhouse gases. It also regulates the identification and disposal of products and devices that contain these gases. Since July 4, 2007, responsible bodies must check their stationary refrigeration systems for leaks at regular intervals, and have any leaks eliminated immediately. Directive (EC) No. 303/2008 contains stipulations on the training and certification of companies and personnel that are permitted to execute the specified activities. Obligations of the responsible bodies: ▪ Directive (EC) No. 842/2006 already imposed a number of obligations upon responsible bodies regarding certain fluorinated greenhouse gases. The new Ordinance on Fluorinated Greenhouse Gases upholds these to a large extent. Some duties are added while others are designed different- ly by this new ordinance. Please refer to the text of this ordinance for a complete overview of the individual responsibilities of responsible bodies. ▪ General obligation to reduce emissions. ▪ Only certified companies may maintain, repair or decommission refrigeration systems. The re- sponsible bodies must verify that these companies are certified. ▪ Regular leak tests of stationary refrigeration systems by certified personnel (such as Huber service engineers). The required test interval is based on the refrigerant filling capacity and the type of refrigerant, converted to CO22 equivalent. ▪ Responsibility of responsible bodies operating a plant to recover F-gases by certified personnel. ▪ Obligatory documentation requirement in the refrigeration system’s operation manual, specifying type and volume of refrigerant used or recovered. The responsible body must keep the records for at least 5 years after their creation and present it to the responsible authority upon request. ▪ Temperature control units with natural refrigerants (NR) are exempt from this Directive. ▪ Please refer to the data sheet or rating plate of your temperature control unit for the quantity and type of refrigerant. ▪ Additional information about the definition of the inspection interval can be found on our web- site. 1.4.2 Requirements for operators Work on the temperature control unit is reserved for appropriately qualified specialists, who have been assigned and trained by the responsible body to do so. Operators must be at least 18 years old. Under 18-year olds may operate the temperature control unit only under the supervision of a quali- fied specialist. The operator is responsible vis-a-vis third-parties in the work area. 1.4.3 Obligations of the operators Carefully read the operation manual before operating the temperature control unit. Please observe the safety instructions. When operating the temperature control unit, wear appropriate personal protective equipment (e.g. safety goggles, protective gloves, non-slip shoes).

The workstation is located at the control panel in front of the temperature control unit. The work- station is determined by the customer's connected peripheries. Accordingly, it must be designed safe by the responsible body. The workstation design also depends on the applicable requirements of the German occupational health and safety regulations [BetrSichV] and the risk analysis for the workstation. 1.5.2 Safety devices to DIN 12876 The rating of your temperature control unit is stated on the data sheet in the appendix. Classification Temperature control medium Technical requirements Identification d) I Non-combustible a) Overheat protection c) NFL II Combustible b) Adjustable overheat protection FL III Combustible b) Adjustable overtemperature protection and additional low-level protection FL a) Usually water; other fluids only if non-combustible even within the temperature range of an individual fault. b) The temperature control media must have a fire point of ≥ 65 °C. c) The overheat protection can, for instance, be realized using a suitable fill level sensor or a suitable temperature limiter. d) Optional at the choice of the manufacturer. ▪ Temperature control units with heating correspond to class number III/FL.

Temperature control units with >Mains isolator< [36] (gray) and >Emergency stop switch< [70] (red/yellow): Press the >Emergency stop switch< [70]. Then turn the >Main switch< [36] to the “0” position! Temperature control units with >Mains switch< [37]: Power supply via socket: Disconnect the temperature control unit from the power supply. Then turn the >Mains isolator< [37] to the “0” position! Power supply via hard wiring: Disconnect the power grid supply by means of the build- ing’s circuit breaker. Then turn the >Mains isolator< [37] to the “0” position! Temperature control units without a switch or inside a protective housing: Connection via sock- et: Disconnect the temperature control unit from the power supply. Connection via hard wiring: Disconnect the power grid supply by means of the building’s circuit breaker! 1.5.3.1 Power interruption Following a power outage (or when switching on the temperature control unit), this function can be used to determine how the temperature control unit is supposed to respond. Auto start function switched off The temperature control is started only by manual input when the temperature control unit is turned on. Auto start function switched on The temperature control unit is set to the same state it was in before the power outage. For exam- ple, before the power outage: Temperature control is off; after power outage: Temperature control is off. If temperature control was active during a power outage, the process will automatically con- tinue after the power outage. → Page 33, section »Changing the Auto-Start function«. 1.6 Exemplary illustrations of the cooling variants Example: Air and water cooling

Room air/cooling water Consequences of, for instance, contamination of the liquefier fins, inadequate clearance between temperature control unit to wall/bath wall, room air/cooling water too warm, cooling water differ- ential pressure too low, suction strainer contamination: The refrigerant in the coolant circuit can no longer fully discharge the admitted energy to the room air/cooling water. Thus there is not sufficient liquefied refrigerant available, the condensation temperature and the energy consumption to rise. Coolant circuit Consequences of inadequate refrigerant quantity/rising condensation temperature: Not all the cooling capacity from the coolant circuit is available at the evaporator. This means reduced energy transmission from the thermal fluid circuit. Thermal fluid circuit Consequence of inadequate energy dissipation from the thermal fluid: The thermal fluid can only dissipate the energy from your application to a limited extent. Application Consequences of inadequate energy dissipation from the application: The energy created (exother- mic) in the application can no longer be fully dissipated. Temperature control unit An electronically-controlled expansion valve is used in the temperature control unit to optimize the power adjustment. The expansion valve always provisions the maximum possible cooling capacity within the permissible ambient temperature range. The temperature control unit switches off when the upper range is reached (maximum permissible ambient temperature). Air cooling: Air inlet Water cooling: Water connection

Observe the wiring diagram. → From page 50, section »Annex«. 2.8.1 Connecting an externally closed application Overpressure in the application (e.g. > 0.5 bar (g) with glass apparatus) MATERIAL DAMAGE TO THE APPLICATION  Provide an overpressure protective device to prevent damage to the application.  Do not install valves/quick-release couplings in the feed/discharge lines from the temperature control unit to the application and from the application to the temperature control unit.  If valves/quick-release couplings are required:  Install burst disks on the application itself (at the feed and discharge lines).  Install a bypass upstream of the valves/quick-release couplings for the application.  Matching accessories (e.g. bypasses to reduce pressure) can be found in the Huber catalog. To enable your application to be operated correctly and eliminate air bubbles from the system, you must ensure that the >Circulation flow< [1] connection from the temperature control unit is at- tached to the lower connection point of the application and the >Circulation return< [2] into the temperature control unit is attached to the higher connection point of the application. PROCEDURE  Remove the screw plugs from the >Circulation flow< [1] and >Circulation return< [2] connec- tions.  Then connect your application to the temperature control unit using suitable thermal fluid hoses. Observe the table with the wrench sizes. → Page 26, section »Wrench sizes and torques«.  Check the connections for leaks. 2.9 Connecting to the power supply Based on local circumstances, it may be that you need to use an alternative power cable instead of the supplied original power cable. Do not use a power cable that is longer than 3 m to be able to disconnect the temperature control unit at any time from the mains. Have the mains cable only replaced by a qualified electrician. 2.9.1 Connection using socket with protective earth (PE) Connecting to a power socket without protective earth (PE) MORTAL DANGER FROM ELECTRIC SHOCK  Always connect the temperature control unit to safety sockets (PE). Damaged power cable/power cable connection MORTAL DANGER FROM ELECTRIC SHOCK  Do not start up the temperature control unit.  Isolate the temperature control unit from the power supply.  Have the power supply cable/power supply connection replaced and inspected by an electri- cian.  Do not use a power cable that is longer than 3 m.

3.1.1 General functions This temperature control unit is designed for externally closed applications. → Page 28, section »Connecting an externally closed application«. Circulating coolers are temperature control units, which are mainly used to dissipate process heat as well as a cost effective alternative to cooling water (drinking water). A rotary evaporator and a vacuum pump can be placed on top of the temperature control unit to save space. Due to powerful refrigeration engineering, short cooling rates can be achieved. 3.1.2 Other functions A pump ensures good circulation of the thermal fluid. The LED display shows the current tempera- ture. A new setpoint can be easily entered with a simple keyboard. 3.2 Information on the thermal fluids Non-compliance with the safety data sheet for the thermal fluid to be used INJURIES  Risk of injury to the eyes, skin, respiratory tract.  The safety data sheet for the thermal fluid to be used must be read prior to using it and its content must be respected.  Observe the local regulations/work instructions.  Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety goggles, safety footwear).  Danger of slipping because floor and work area are contaminated. Clean the workplace; ob- serve the proper disposal of thermal fluid and aids. → Page 15, section »Proper disposal of re- sources and consumables«. Non-compliance with the compatibility between the thermal fluid and your temperature control unit MATERIAL DAMAGE  Observe the classification of your temperature control unit according to DIN 12876.  Ensure the following materials are resistant with respect to the thermal fluid: Stainless steel 1.4301/ 1.4401 (V2A), copper, nickel, FKM, red bronze/brass and silver solder.  The maximum viscosity of the thermal fluid must not exceed 50 mm²/s at the lowest working temperature!  The maximum density of the thermal fluid may not exceed 1 kg/dm³! Mixing different thermofluids in a thermal fluid circuit PROPERTY DAMAGE  Do not mix different types of thermofluid (such as mineral oil, silicone oil, synthetic oil, water, etc.) in a thermofluid circuit.  The thermal fluid circuit must be rinsed when changing from one type of thermal fluid to an- other. No residues of the previous type of thermal fluid may remain in the thermal fluid circuit.

Thermal fluid: Water without ethylene glycol Use ≥ +3 °C Thermal fluid: Water-ethylene glycol mixture Use < +3 °C Thermal fluid composition The mixture’s temperature must be 10 K below the permissible min. tem- perature. For the permissible temperature range, refer to the datasheet. → From page 50, section »Annex«. 3.3 To be noted when planning the test Observe the intended operation. → Page 14, section »Proper operation«. The focus is on your application. Bear in mind that system performance is influenced by heat trans- fer, temperature, thermal fluid viscosity, volume flow, and flow speed. ▪ Make sure the electrical connection is adequately dimensioned. ▪ The installation location of the temperature control unit should be selected so as to ensure ade- quate fresh air, even with water-cooled chillers. ▪ The maximum flow pressure of a temperature control unit must be taken into account in case of pressure-sensitive applications, such as glass reactors. ▪ Cross-section reduction or shut-off in the thermal fluid circuit must be avoided. Take appropriate measures to limit the pressure in the system. Observe the data sheet of your glass apparatus and the data sheet of your temperature control unit. → From page 50, section »Annex«. ▪ Check whether it is necessary to use an external bypass for temperature control units without pressure limitation. ▪ In order to prevent the risk of overpressure in the system, the thermal fluid must always be ad- justed to room temperature before switching off. This will prevent damage to the temperature control unit or the application. Any isolating valves must remain open (pressure equalization). ▪ Select the thermal fluid to be used in such a way that it not only permits the minimum and maxi- mum working temperature but is also suitable with regard to fire point, boiling point, and viscosi- ty. In addition, the thermal fluid must be compatible with all the materials in your system. ▪ Avoid bending the temperature control and cooling water hoses (if required). Use suitable angle pieces and lay the hose connections with a large radius. Take the minimum bending radius from the data sheet of the temperature control hoses used. ▪ The selected hose connections must be able to withstand the thermal fluid, the working tempera- tures and the admissible maximum pressure. ▪ Check the hoses at regular intervals for any material fatigue (e.g. cracks, leaks). ▪ Keep the temperature control hoses as short as possible - The inside diameters of the temperature control hoses must correspond at least to the pump connections. Select bigger inside diameters for longer line lengths to compensate for pressure loss in the piping. - The viscosity of the thermal fluid determines the pressure drop and influences the tem- perature control result, especially at low working temperatures. - Too small connectors and couplers and valves can generate significant flow resistance. Your application will therefore be slower to reach its design temperature. ▪ Basically, you should only use the thermal fluid recommended by the manufacturer and only within the usable temperature and pressure range. Thermal fluid: Water

the temperature control is close to the boiling temperature of the thermal fluid. ▪ Fill the temperature control unit slowly, carefully and evenly. Wear the necessary personal pro- tective equipment, such as goggles, heat-proof and chemically resistant gloves, etc. ▪ The temperature control circuit must be vented after filling and setting all required parameters. This is required to ensure trouble-free operation of the temperature control unit and hence your application. For water-cooled temperature control units, please take the cooling water temperature necessary for perfect operation and the required differential pressure from the data sheet. → From page 50, section »Annex«. 3.4 Display and control instruments 3.4.1 Display The value of the internal temperature is displayed.

Extremely hot / cold surfaces, connections and thermal fluids BURNS/FREEZING OF LIMBS  Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on the operating mode.  Avoid direct contact with surfaces, connections and thermal fluids!  Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety goggles). During an active circulation, the thermal fluid circuit is shut off by shut-off valves MATERIAL DAMAGE TO THE CIRCULATING PUMPS INSTALLED IN THE TEMPERATURE CONTROL UNIT  Do not close the thermal fluid circuit during an active circulation by means of shut-off valves.  Warm the thermal fluid to room temperature before stopping the circulation.

Non-compliance with the safety data sheet for the thermal fluid to be used INJURIES  Risk of injury to the eyes, skin, respiratory tract.  The safety data sheet for the thermal fluid to be used must be read prior to using it and its content must be respected.  Observe the local regulations/work instructions.  Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety goggles, safety footwear).  Danger of slipping because floor and work area are contaminated. Clean the workplace; ob- serve the proper disposal of thermal fluid and aids. → Page 15, section »Proper disposal of re- sources and consumables«. Semi-automatic venting DAMAGE TO THE TEMPERATURE CONTROL UNIT  An elevated tolerance time for the pressure drop can damage the pump if the thermal fluid level in the system is also too low.  Constantly observe the thermal fluid level on the >Level indicator/Level< [25]. Fill up the thermal fluid during the venting phase so the thermal fluid level does not fall below the minimum mark. Calculate whether the capacity of the >Expansion vessel< [18] can absorb the expansion volume during operation. Assume the following volumes for this calculation: [Minimum filling capacity of the temperature control unit] + [Volume of the thermal fluid hoses] + [Jacket volume of your appli- cation] + [10% / 100 K]. ▪ During the fill process, ensure any necessary measures, such as earthing the tanks, funnels and other aids, have been taken. ▪ Fill to the lowest possible height. PROCEDURE  Ensure that a hose was installed at the >Overflow< [12] (if installed). The other end of the hose must be inserted in a suitable collecting container. Excess thermal flu- id will leak at this point when the temperature control unit is overfilled. Hose and container must be resistant to the thermal fluid and the temperature.  Manually open the >Filling port< [17].  Carefully pour suitable thermal fluid, using the filling accessories (funnel and/or beaker) into the >Filling port< [17]. The thermal fluid flows into the temperature control unit and through the hose connections to the external application. The fill levels are displayed in the >Level indica- tor/Level< [25] Follow the instructions for the proper disposal when cleaning filling accessories. → Page 15, section »Proper disposal of resources and consumables«.  Switch on the temperature control unit.  Set the setpoint to 20 °C. → Page 33, section »Set/change setpoint«. Fill levels in the >Level indicator/Level< [25]

 Refill thermal fluid. Observe the fill level in the >Level indicator/Level< [25] The filling/venting process is complete when the thermal fluid is 1 cm below the max. mark of the >Level indica- tor/Level< [25]. If, with externally closed applications (reactors), the fluid level in the fill level display remains the same when the pump is running and when the pump has stopped, the application has been vented.  Stop the circulation by pressing the >Start/Stop button< [E].  Switch off the temperature control unit.  Manually close the >Filling port< [17].  Check the level of the collecting container at regular intervals. Empty the container when neces- sary and dispose of its contents properly.  Manually close the >Filling port< [17]. The temperature control unit is now filled. Venting must be performed especially during commissioning and after a change of thermal fluid. This is the only way to ensure trouble-free operation. Note that the volume expansion of the thermal fluid depends on the working temperature range you wish to work in. At the “lowest” working temperature, do not go below the minimum mark of the >Lev- el indicator/Level< [25] and at the “highest” working temperature, do not go above the maximum mark. In case of overfilling, drain the excess amount of thermal fluid. → Page 37, section »Draining externally closed applications«. Check if the thermal fluid can be reused. Follow the instructions for the proper disposal. → Page 15, section »Proper disposal of resources and consumables«. 4.2.2 Draining externally closed applications Hot or very cold thermal fluid SEVERE BURNS/FROSTBITE OF LIMBS  Before draining, ensure that the thermal fluid has room temperature (20 °C).  If, at this temperature, the thermal fluid is too viscous to be drained: Control the temperature of the thermal fluid for a few minutes until the viscosity will allow drainage. Never control the temperature of the thermal fluid when the drain is open.  Danger of burns when draining thermal fluids at temperatures above 20 °C.  Wear your Personal Protective Equipment for draining.  Only drain using suitable drainage hose and collecting container. These must be compatible with the thermal fluid and its temperature. PROCEDURE Temperature control units with >Drain valve thermal fluid< [3].  Remove the knurled screw at the >Drain< [8].  Connect a suitable drain hose to the >Drain< [8].  Place the other end of the hose in a suitable container.  Open the >Drain valve thermal fluid< [3] by turning it counterclockwise (turn 90° left as far as it will go). The thermal fluid will flow from the external application via the temperature control unit and the draining hose into the container. Check if the thermal fluid can be reused. Follow the in- structions for the proper disposal. → Page 15, section »Proper disposal of resources and con- sumables«.  Wait until the external application and the temperature control unit are empty.  Open the connection >Circulation flow< [1].  Open the connection >Circulation return< [2].  Leave the temperature control unit open for a while to allow it to dry out and the residue to drain. Without screw caps and with >Drain valve thermal fluid< [3] open.  Close the >Drain valve thermal fluid< [3] by turning it clockwise (turn 90° right as far as it will go).  Close the connection >Circulation flow< [1].  Close the connection >Circulation return< [2].  After drying out, remove the drain hose and re-fit the knurled screw to the >Drain< [8]. The temperature control unit is now drained.

retardation during future uses (e.g. use of a silicone oil at temperatures above about 100 °C). PROCEDURE  Drain the temperature control unit. → Page 37, section »Draining externally closed applica- tions«. Residual thermal fluid can remain in the pump chamber and the internal lines after draining. Leave the temperature control unit with open valves for a while.  Leave the drain hose mounted to the >Drain< [8].  Check the fill level in the collecting container at the other end of the drain hose. Follow the in- structions for the proper disposal of thermal fluid. → Page 15, section »Proper disposal of re- sources and consumables«.  Close the drain valves on the temperature control unit by turning them clockwise (turn 90° right as far as they will go).  Connect the >Circulation flow< [1] with the >Circulation return< [2] at the temperature control using a bypass hose. Perform the following steps without attaching a short circuit hose, if the application used by you (externally closed) is also dirty. In this case, leave your externally closed application connected to the temperature control unit. This rinses the temperature control unit and your application at the same time.  Fill the system (minimum fill level) with the thermal fluid you wish to use. → Page 36, section »Filling and venting externally closed application«.  Vent the system. → Page 36, section »Filling and venting externally closed application«.  Adjust the setpoint to the thermal fluid used. → Page 33, section »Set/change setpoint«.  Start the circulation. The length of rinsing depends on the level of soiling.  Stop the circulation.  Drain the temperature control unit. → Page 37, section »Draining externally closed applica- tions«.  Repeat the steps “Filling”, “Venting”, “Start/Stop circulation” and “Draining” until the drained thermal fluid remains clear.  Remove the bypass hose after completely draining the temperature control unit. Leave an application connected, if you have simultaneously rinsed a used application (externally closed).  Leave the >Drain< [8] open for a while to allow the thermal fluid remaining in the temperature control unit to evaporate.  Close the >Drain< [8] once the residual thermal fluid has evaporated.  Dismount the drain hose.  Remove the collecting container.  Discard the collecting container, including its contents, properly. Follow the instructions for the proper disposal. → Page 15, section »Proper disposal of resources and consumables«.  Re-connect your application. (Only if you have rinsed the thermal fluid circuit using a bypass hose.)  Fill the temperature control unit with thermal fluid. → Page 36, section »Filling and venting externally closed application«.  Vent the temperature control unit. → Page 36, section »Filling and venting externally closed application«. An externally open application does not need to be vented.  Restart the temperature control unit in normal mode. Example: Connecting a short circuit hose
