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.
