Float-Controlled Condensate Trap, PN 63
1 Safety instructions
1.1 Proper use
Any improper use, intervention in the design and deviation from the design data automatically lead to termination of the
warranty. The float-controlled condensate trap is designed for the discharge of condensate from steam, compressed air and
pressure gas systems. Any other usage is not permitted. The manufacturer is not liable for damage resulting from any other
usage. The user or operator bears the risk in this case. This also applies analogously to incorrect assembly, start-up, use and
maintenance.
1.2 Warnings and symbols
■Personal risk due to escaping operating medium because of pressure, temperature and weight. Failure to comply with
these warnings results in the risk of accidents.
■Follow the instructions in this operating manual.
■The operator must ensure that this operating manual and, if necessary, other relevant documents are available on site.
■Only trained or instructed personnel may be assigned to handling this equipment.
■Any mode of operation that may impair safety must be avoided.

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
■To get the proper function of the float control assembly in applications of pressure gases, the gases in the condensate trap
housing must be led into the gas chamber with the same operating pressure above the condensate trap (pressure compen-
sation). For this purpose the control screw (4) in models 1313-N can be replaced by a cutting ring union and a compensating
line leading upward can be installed. The pressure compensation for the models 1318-N is not strongly recommended.
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
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 supportingbrackets, which are welded onto the housing.
■
■ For the model WO-1313-(N), remove the transport sefety device
(see Picture 4) before start-up and replace it with thecontrol screw provided.
■ For the model EF-1318-(N), remove the fuse wire completely before start up.
To avoid downtimes, it is recommended to install stop valves with
bypass to pipeline, both in front of and behind the condensate trap.

4 Start-Up
Shut off the float-controlled condensat trap on both sides during the strength tests, because the control unit is not suitable
for the design test pressure according to the nameplate.
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 / 5 / 6 / 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 or 13) for a quarter rotation, while no con-
densate 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 can be easily
moved. If necessary, disassemble and clean the float control assembly (7). If damages/ wears are detected on parts or on the
sealing surface, the complete float control assembly (7) 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 250 up to 262 kg depending
on the connection sizes. Lifting device is required.
■Loosen the housing screws (5) evenly crosswise. Put down the housing
cover (3). Attention: the housing cover weights about 36 kg.

Screws
Bushing
■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 (8). 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 (7) through the cover opening.
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 250 up to 262 kg depending on the connection sizes. Lifting device is required.
■Loosen the housing screws (5) evenly crosswise. Put down the housing cover (3). Attention: the housing cover weights
about 36 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 (8). The control is detached from
the seat cone by means of gentle blows with a hammer on the front end of centering aid.

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 float control assembly (7) should also be checked according to Section 6.2.
■The dirt, which has been accumulated in the housing, can be removed away by screwing off the screw plug (6).
■For special applications, it is advisable to install a separate upstream strainer.
■The float control assembly (7) usually does not to be special maintained. The maintenance depends primarily on the wear
resistance of the valve gasket. See Section 6.1 and 6.2.

6.2 Disassembling, cleaning and assembling the float control (Picture 6)
■After removing the cotter pin (p), the rotary valve (v) can be simply pulled out
to the side.
■Clean the parts using, for example, benzine.
■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) must be replaced. The
thorough leakage test must 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.
■It must be possible to move the float up and down easily by hand.
