Water supply
CAUTION
Avoid operating the pump without a water supply line connected and fed from the source. The
water resource yield must correspond with at least 12 litres per hour, at the minimum pressure of 1 bar. If the
purity of supplied water cannot be guaranteed, the system needs a water filter placed before the pump inlet to
avoid influx of solid contaminants inside the pump.
Having connected the hoses, open the water tap fully to its limit position and depress the control lever on the
high-pressure gun. To deaerate the pump hoses, keep the gun in depressed position until you observe an
even flow of water out of the quick-coupler. Insert the adaptor quick-coupler with the high-pressure nozzle.
If
the pump has not developed pressure within 30 seconds following its
commissioning, switch the engine off and proceed in compliance with instructions
defined in the Troubleshooting section! Any dry cycling of the pump for a period
exceeding 30 seconds may result in damage!
Any material damage caused due to inobservance of this instruction renders the warranty void.
CAUTION WHEN USING SELF-PRIMING FUNCTION
For pumps provided with the
SELF-PRIMING
function:
The high-pressure washer and the filling hose from
WPW Center (special accessories, catalogue number SP000-HI001) can be used for removal of surface
water, e.g. from storm water reservoirs. The water in reservoir must be clean, free of any contaminants or
sludge. Contaminated water causes irreversible damage to internal components of the high-pressure pump
.
Fill the filling hose with water up to the rim to eliminate any air bubbles inside.
Connect the hose to the filler neck directly (without the quick-coupler adaptor, included in the delivery). Make
sure the sealing between the hose and the pump neck is free of any damage.
Submerge the other end into the water reservoir. Remove the nozzle from the quick-coupler on the end of
high-pressure gun adaptor. Start the engine and depress the gun control lever to let the water flow out freely,
until the stream comes out free of any air bubbles. Once the system has been bled, fit the nozzle and restart
the engine again. The pump is ready for operation now. If the pump has not developed pressure with the
engine running for 30 seconds, switch the engine off and proceed in accordance with instructions defined in
the Troubleshooting section.
CAUTION If the pump draws air in, the whole deaerating procedure must be repeated.
