Guidelines for liquid spraying equipment
* The accident prevention directive (BGV D 15)
Work with Jets of Liquids is applicable. In
accordance with these guidelines, highpressure spraying equipment must be
checked at least every 12 months by an
expert and the results of the inspection
recorded in writing.
The warranty only applies if the dealer fills in,
stamps and signs the enclosed reply card when
the unit is sold and the purchaser then returns it
to the appropriate local distributor.
In the event of a warranty claim, please contact
your dealer or the nearest authorised AfterSales Service office and produce both
accessories and proof of purchase.
GENERAL INSTRUCTIONS
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 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
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 sealed. Adjustment can
only be made by After-Sales Service.
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.
* 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.
