When setting up in rooms, the local
building regulations for channelling
exhaust gas into the open must be
observed. Provide sufficient
ventilation.
The machine must be constantly
supervised so that the operating
personnel is able to notice if the
flame goes out.
CAUTION! If the machine runs dry,
the fuel pump will be destroyed.
Electrical System
Check the mains voltage of the
machine before connecting it to the
power supply. Make sure that the
voltage indicated on the rating plate
corresponds to the local mains
voltage.
It is strongly recommended that the
power supply for this unit be
connected via a residual-current-
operated circuit-breaker. This device
cuts off the power supply if the
leakage current to earth exceeds 30
mA for 30 ms, or contains an earth
testing-current circuit.
When using an extension cable, all
current-carrying parts (plug, line,
electrical sockets) must be arranged
so that the protection type „water-
tight“ is fulfilled. This can also be
achieved with protected routing.
CAUTION!
Never spray the machine itself or
other electrical appliances with
water: danger of injury due to short
circuiting.
Always handle the power cable with
caution. Make sure that you
- never kink the power cable
- do not set anything on it
- never pinch or crush it anywhere
- Never touch the plug or power
cable with wet hands. Always
hold the power cable by the plug
when plugging in and pulling out.
Do not use the machine in the
immediate vicinity of heat sources
(fire, radiators, heater blowers or
other heat-radiating devices) and
never cover the machine.
Set up the unit in a dry location.
Never attempt to continue operating,
to dismantle or to make any changes
on the machine yourself if
- the power cable or the plug of the
machine are damaged.
- a foreign object of liquid has
reached the inside of the machine.
- the machine is not operating
normally.
- unusual changes in the operating
condition occur.
Please contact the Wap Customer
Service or an authorised specialised
workshop!
The electrical connection must be
carried out by a qualified electrician.
The latest edition of the IEC
regulations must be observed
CAUTION!
Always disconnect power plug before working on the machine!
2.1.1 Inspections and Approvals
The machine corresponds to the German „Guidelines for Liquid Sprayers“ The high-pressure cleaner must be
inspected by an expert for operating safety as described in these guidelines and the „UVV - Working with Liquid
Sprayers (VBG 87)“ as required, however at least every 12 months.
The company owner must ensure that the major parts (e.g. safety equipment, pump, hoses, spraying device and power
cable) of the liquid sprayer are checked for proper condition each time before operating.
The German standard VDE 0701 (IEC 335) specifies that the insulation resistance and the leakage current must be
measured on electrical devices each time servicing or changes to the protective-conductor resistance are carried out.
In addition, a visual inspection of the power cable, a voltage and current measurement and a functional check must
be carried out. Our Customer Service technicians are available to you for expert help.
You can conclude maintenance and repeat inspection contracts with us. We will confirm the inspection results in
writing.
The water capacity is less than 10 l. The design and test pressure correspond to the German steam boiler ordinance.
No design approval, permit application or approval testing is required.

Heymanns-Verlag KG, Luxemburger Straße 449, 50939 Köln, Germany or the responsible employer’s liability
insurance association.
