In the lowest position of the float the outlet cross-section is close. Rising of the liquid level lifts the float and opens the outlet. Condensate will be discharged through the upturned immersion tube. Decreasing condensate level closes the outlet again. 2.6 Compensation line ■ In order to get proper function, the non-condensable gas must be able to leave the housing. Due to the vertical installation, the non-condensable gas is able to leave the housing and flows into the steam/gas chamber above it, which has the same pressure level. If the self-venting through the pipe must be extended, the control screw (4) can be replaced by a cutting ring screw bolt and a compensation line can be installed leading upwards. 2.7 Automatic venting ■ In the case of steam applications, automatic venting must be provided (vent jet). 2.8 Gastight under-level float control (only for gas applications) ■ For gas applications, a gastight under-level float control is nearly exclusively used. In the case of using such float control units, please note separate and additional documents. * Special control units with oval-float Discharge capacity in kg/h Pressure difference in bar (with reference to atmospheric pressure) 20/340 DN 50 / 65 50/1650 50/1100 DN 80 / 100 Discharge capacity in kg/h Pressure difference in bar (with reference to atmospheric pressure) Picture 3 * only with screw material A4-70/ 1,4571/ 1.4104 Picture 4

Subject to modifications 3 Assembly ■ The condensate trap has to be screwed into a pipeline between flanges. ■ Remove transport caps from inlet and outlet. Also remove the device for trans- port safety in accordance with sticker. ■ Fitting direction: according to Picture 1 and Picture 2. ■ Supporting brackets: The weight of the condensate trap must be taken up by the supporting brackets, which are welded onto the housing. A operation only on the four feets is not allowed. ■ To avoid downtimes, it is recommended to install stop valves with bypass to pipeline, both in front of and behind the condensate trap. ■ For the model WO-1213-(N), remove the transport sefety device (see Picture 5) before start-up and replace it with the control screw provided. ■ For the model EF-1218-(N), remove the fuse wire completely before start up. 4 Start-Up Shut off the housing on both sides during strength tests with PT pressure. The float-controlled unit is only suitable up to PS pressure value or alternative PT value shown in brackets according name plate. The lower value is max. allowable pressure. A pressure test with design pressure (PT) will destroy the float. The pressure build-up and heating-up of the housing should not take place abruptly. If leakage is detected after the first inspection, the screws (4 / 6 / 12 / 13) can be fixed under consideration of the given torque moments, as given in Section 6.5. The screws can only be tightened on when the housing is unpressurized and at room temperature. 5 Observation and control The function’s failure can be observed either as condensate blockage or as gas/ steam leakage. ■ Condensate blockage can be determined by a): loosen the control screw (4) for a quarter rotation, while no condensate leakage should occur; and by b): a surface thermometer on the housing for steam applications (if necessary, please consult with Rifox). ■ Gas / steam leakage: can be determined by an ultrasonic measuring device, and for steam applications by a surface thermometer. In case of steam leakage, open the condensate trap according to Section 6.1. Make sure that float (10) can be easily moved. If necessary, disassemble and clean the float control assembly (8). If damages/ wears are detected on parts or on the sealing surface, the complete float control assembly (8) should be replaced. 6 Maintenance / Inspection 6.1 Opening the steam trap and dismantling the float control 6.1.1 Float control unit with spherical float ■ The steam trap has to be depressurized. Shut off the system securely in front of and behind the steam trap. ■ Release any remaining pressure in the housing by loosening the control screw (4 or 13) by only a quarter turn. ■ Dismantle the steam trap from the pipeline system. Loosen the flange connections and lift out of the pipeline carefully and place on the floor. Attention: The condensate trap weights from 170 up to 200 kg depending on the connection sizes. Lifting device is required. ■ Loosen the housing screws (12) evenly crosswise. Put down the housing cover (1). Attention: the housing cover weights about 16 kg. ■ The float control unit is dismantled with a centering aid that is inserted in the bushing provided with 2 slots. By turning counterclockwise (3-4 turns) the bushing is screwed out of the control support body (9). The control unit is detached from the seat cone by means of gentle blows with a hammer on the front end of centering aid. ■ Screw out the bushing completely. ■ Remove float control unit (8) through the cover opening.

Subject to modifications 6.1.2 Float control unit with oval float ■ The steam trap has to be depressurized. Shut off the system securely in front of and behind the steam trap. ■ Release any remaining pressure in the housing by loosening the control screw (4) by only a quarter turn. ■ Dismantle the steam trap from the pipeline system. Loosen the flange connections and lift out of the pipeline carefully and place on the floor. Attention: The condensate trap weights from 170up to 200 kg depending on the connection sizes. Lifting device is required. ■ Loosen the housing screws (12) evenly crosswise. Put down the housing cover (1). Attention: the housing cover weights about 16 kg. ■ Loosen the screws between float and fork by using a flat ring spanner. ■ Remove the screws and the spring washer. ■ Turn the oval float inside the housing and lift it out vertically. ■ If only the float has to be replaced, continue with section 6.3.2 point 3. ■ The supporting body with fork is dismantled with a centering aid that is inserted in the bushing provided with 2 slots. By turning counterclockwise (3-4 turns), the bushing is screwed out of the control support body (9). The control is detached from the seat cone by means of gentle blows with a hammer on the front end of centering aid. ■ Screw out the bushing completely. ■ Remove supporting body with fork through the cover opening. 6.2 Disassembling, cleaning and assembling the float control (Picture 6) ■ After removing the cotter pin (p), the rotary valve (v) can be pulled out to the side easily. ■ Clean the parts using petrol for example. ■ Check the rotary valve (v) for wear along the sealing edge. If wear is detected, the support body (b) together with the rotary valve (v) has to be replaced. The thorough leakage test has to be carried out by RIFOX. ■ During assembly ensure that the notch in the rotary valve (v) points to the punch mark on the support body (b) and the cotter pin (p) is inserted and secured again carefully. ■ Ensure the float can be moved up and down easily by hand. 6.3 Installation of the float control unit and assemble the steam trap 6.3.1 Float control unit with spherical float ■ The complete float control assembly (8) is inserted into the conical housing seat with the support body. Ensure the tube is positioned vertically downwards. ■ Screw in the bushing into the control support body (b) and tighten with the centering aid described in Section 6.1. ■ Check the housing gasket (2), replace if it is damaged. ■ Put on the housing cover (1). ■ Tighten the housing screws (12) evenly crosswise. Tightening torque according to Section 6.5. 6.3.2 Float control unit with oval float ■ The supporting body, float fork and rotary slide valve assembly is inserted into the conical housing seat with the support body. Ensure the tube is positioned vertically downwards. ■ Screw in the bushing into the control support body (b) and tighten with the centering aid described in Section 6.1. ■ Insert the oval float vertically into the housing. Turn the oval float inside the housing to have the connection points of the float fork and the float are aligned. The filling nipple of the oval float should point towards the housing opening. ■ Attach the connecting elements (screws and spring washer) by hand and tighten with a flat ring spanner. ■ Check the housing gasket (2), replace if it is damaged. ■ Put on the housing cover (1). ■ Tighten the housing screws (12) evenly crosswise.

Subject to modifi cations 6.4 Care and maintenance ■ In the case of a great risk of dirt accumulation, the housing, when it is depressurized, should be rinsed thoroughly from time to time. If necessary, the fl oat control assembly (8) should also be checked according to Section 6.2. ■ The dirt, which has been accumulated in the housing, can be removed away by opening the screw plug (6). ■ For special applications it might be reasonable to install a separate upstream strainer. ■ The fl oat control assembly (8) usually does not require special treatment. The maintenance depends primarily on the wear resistance of the valve gasket.
