shock. If power is interrupted in the line, the
GFCI will automatically re-close the circuit
to the load after power is restored. Depending on the GFCI model, it may be necessary to manually operate the reset button to
restore power to the GFCI load circuit. If replacement of the plug or cord is needed use
identical replacement parts.
WATER SUPPLY
몇 CAUTION
When connecting the water inlet to the water supply mains, local regulations of your
water company must be observed. In some
areas the unit must not be connected directly 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 3/4 inch
in diameter.
– Flow rate of water supply must not fall
below 5 GPM (gallons per minute).
– Flow rate can be determined by running
the water for one minute into an empty
5-gallon container.
– The water supply temperature must not
exceed 86°F/30°C.
– Never use the pressure washer to draw
in water contaminated with solvents,
e.g. paint thinners, gasoline, oil, etc.
– Always prevent debris from being
drawn into the unit by using a clean water source. Use additional water filter.
