1.0 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-con trolled condensate trap is designed for the
discharge of condensate from steam, co mpressed air and pressure gas systems. Any other
use is not permissible. The manufacturer is not liable for dam age resulting from any other
use. The user o r operator bears the risk in this case. This also applies analogouslyto
incorrect assembly, startup, use an d maintenance.
1.2 Warnings and symbols
There is a risk of personal injury due to escaping operating medium as well as because of
pressure, temperature and weight. Failure to comply with these warnings may lead to 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 maybe assigned to handling this
equipment. Any mode of operation that mayimpair safety must be avoided.

2.7 Flow control unit: Function / gas compensation
In the lower float position the supply flow is open and closed in upper
position. When reaching a lower tank level the float control unit opens. The
addition to the tank is determined by the dimension Z. To allow a free rising
and failing of the tank level existing in the flow control unit, a pressure
compensation line has to be installed (as shown in figure 2).
3.0 Assembly
3.1 Fitting
Remove protective caps from inlet and outlet.
Fitting position according to Fig. 1 and 2
Flow direction according to the arrow provided on the rating plate
4.0 Maintenance / Inspection
4.1 Opening the flow control unit an d dismantling the float control
1. The condensate trap must be depressurized
2. Remove the flow control unit completely
3. Loosen hexagon nuts (5.) evenly crosswise,take off cover (1).
4. Loosen support screw (10) and unscrew it completely

4.2 Disassembling and cleaning the float control (Fig.3)
1. After removing the cotter pin (i), the rotary valve (d)
is simply pulled out to the side.
2. Clean the parts using, for example, benzine.
3. Check the rotary valve (d) for wear along the sealing edge. If wear is
detected, the support body (c) together with the rotary valve (d)
must be replaced. A precise leak test must be carried out by Rifox.
4. During assembly ensure that the notch in the rotary
valve (d) points to the punch mark on the support body (c)
and the cotter pin (i) is inserted and secured again carefully.
5. The float must be able to move up and down
without resistance.
4.3 Installing the control and assembling
1. The complete float control is inserted into the conical
Housing seat with the support body (8).
Ensure here that the pipe (7) shows upward.
2. The support body (8) is fixed in bush (10) by screwing with a tightening torque approx. 50 Nm.
3. Check the housing gasket (2) and replace necessary.
4. Assembly of housing as shown in figure 1 and acc. to paragraph 3.
5. Tighten housing bolts crosswise. Tighten torque: 70 Nm.
4.4 Care and maintenance, spare parts
In the case of a great risk of dirt accumulation, the housing should be rinsed thoroughly from time to
time, but while depressurized. If necessary, the float control should also be checked according
section 4.2.
In most cases the float control usually does not require special care. Maintenance primarily depends
on the wear resistance of the valve seal. See sections 4.1 and 4.2 in this connection.
Spare parts: Only genuine spare
pa rts may be used.
