WARRANTY
The warranty terms and conditions
issued by our responsible sales
company apply in every country.
Within the warranty period, any
faults in the unit will be rectified free
of charge provided that the problem
was caused by a material defect or
manufacturing error.
The warranty only applies if the
dealer fills in, stamps and signs the
enclosed reply card when the unit is

it to the appropriate local distributor.
In the event of a warranty claim,
please contact your dealer or the
nearest authorised After-Sales
Service office and produce both

GENERAL NOTES
Safety features
*
Overflow valve with two pressure
switches
Reducing the water volume at the
pump head or with the servopress
control opens the overflow valve and
some of the water runs back to the
pump suction end.
If the handgun is closed thus
causing all the water to return to the
pump suction end, the pressure
switch at the overflow valve shuts 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 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 sealed. Adjustment
can only be made by After-Sales
Service.
*
Low water protection
The low water protection stops the
burner being switched on in the
event of a lack of water. A strainer
stops the protection feature
becoming dirty and requires regular
cleaning.
*
Motor protection switch
The motor protection switch
interrupts the circuit should
overloading occur.
Guidelines for liquid spraying
equipment
*
The accident prevention regulation
(VBG 87) "Working with liquid
spraying equipment" applies. 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
*
Test pressure and design of unit
comply with Order governing
boilers as per TRD. 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.
