GROUND FAULT CIRCUIT
INTERRUPTER PROTECTION
WATER SUPPLY
(Cold Water Only)
This product is supplied with a Ground
Fault Circuit Interrupter (GFCI) built into
the power cord plug. This device provides additional protection from the risk
of electric 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.
SERVICING OF A DOUBLE-
INSULATED PRODUCT
In a double-insulated product, two systems of insulation are provided instead
of grounding. No grounding means is
provided on a double-insulated product,
nor should a means for grounding be
added to the product. Servicing a double-insulated product requires extreme
care and knowledge of the system, and
should be done only by qualified service
personnel. Replacement parts for a
double-insulated product must be identical to the parts they replace. A doubleinsulated product is marked with the
words “double-insulatIon” or “double-in-
sulated”. The symbol “®” may also be
marked on the product.
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.
! Water hose must be at least 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 solvents, e.g. paint thinners, gasoline,
oil, etc.
! Always prevent debris from being
drawn into the unit by using a clean
water source.
