WATER SUPPLY
(Cold Water Only)
CAUTION
When connecting the water inlet to the wa-
ter supply mains, local regulations of your
water company must be observed. In some
areas the unit must not be connected di-
rectly to the public drinking water supply.
This is to ensure that there is no feedback
of chemicals into the water supply. Direct
connection via a receiver tank or backflow
preventer, for example, is permitted.
Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.
Garden hose must be at least 1/2
inch or 5/8 inch in diameter.
Flow rate of water supply must not
fall below 2 GPM (gallons per
minute).
Flow rate can be determined by run-
ning the water for one minute into an
empty 5-gallon container.
The water supply temperature must
not exceed 104°F/40°C.
Never use the pressure washer to
draw in water contaminated with sol-
vents, e.g. paint thinners, gasoline,
oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.
