2.4 Discharge capacity (for all four models, for hot condensate)
2.5 Function
■Due to the gravity the condensate flows downwards to the lowest point, which is the condensate trap housing. 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. Consult with Rifox, if necessary.

3 Assembly
The condensate trap has to be screwed into a pipeline between flanges.
■Remove transport caps from inlet and outlet.
■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-1113-(N), remove the transport sefety device (see Picture 5)
before start-up and replace it with the control screw provided.
■ For the model EF-1118-(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) 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) 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 145 up to 160 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.
