Safety features
Overflow valve with two pressure
switches
— When reducing water volume at pump
head or with the servopress control, the
overflow valve will open and part of the
water will flow back to the pump suction
side.
— If the handgun is closed off so that all
the water flows back to the pump suction
side, the pressure switch at the overflow
valve turns off the pump.
— Reopening the handgun causes the
pressure switch at the cylinder head to
switch the pump back on again.
The overflow valve is set at the factory and
lead-sealed. Adjustment can only be made
by After-Sales Service.
Safety valve
— The safety valve opens if the overflow
valve or pressure switch is defective.
The safety valve is set at the factory and

burner being switched on in the event of
a lack of water.
— A strainer prevents dirt accumulation on
the protection and must be regularly
cleaned.

Guidelines for liquid spraying
equipment
— The accident prevention directive
(BGV D 15) Work with Jets of Liquids is
applicable. In accordance with these
guidelines, high-pressure spraying
equipment must be checked at least
every 12 months by an expert and the
results of the inspection recorded in
writing.
Order governing boilers
— The testing pressure and the design of
the unit comply with the steam boiler
directive!.
— The water content of the heating coil is
less than 10 litres. The boiler section of
the unit is thus not subject to installation
regulations. Local building regulations
are to be heeded.
Switching on procedures
— Switching on procedures generate brief
voltage drops.
— Impairments of other appliances can
occur in cases of unfavourable mains
conditions.
— No problems are to be expected with a
mains impedance of less than 0,15 ohm.
