– While reducing the water supply at the pump head
or with the Servopress - regulation the overflow
valve opens and part of the water flows back to the
pump suck side.
– If the hand-spray gun is closed, so that the whole
water flows back to the pump suck side, the pres-
sure switch at the overflow valve shuts down the
pump.
– If the hand spray gun is opened, the pressure switch
on the cylinder head turns the pump back on.
The overflow valve is set by the manufacturer and
sealed. Setting only by customer service.
– The safety valve opens, when the overflow valve
resp. the pressure switch is broken.
The safety valve is set by the manufacturer and sealed.
Setting only by customer service.
– The water shortage safeguard prevents the burner
to be turned on when there is water shortage.
– A sieve prevents the contamination of the safe-
guard and must be cleaned regular.

when the waste gases have reached very high tem-
peratures.

manufacturer
Note: A system care bottle is included in the delivery.
 Replace the system care bottle.
 Determining the hardness of tap water:
– through the public water supply works,
– using a hardness tester (order no. 6.768-004)
 Set the service switch according to the water hard-
ness in the table.

– RM 110 prevents calcification of the heating coil in
the presence of hard water.
– RM 111 prevents the formation of black water and
cares for the pump in the presence of soft water.
