Connecting the water supply

WARNING
￭ Releasing the spray gun trigger causes a kickback in the
water hose. A kickback can force dirty water back into the
drinking water main. This can pollute the drinking water.
► Do not connect the pressure washer directly
to the drinking water main.
► A backflow preventer complying with the applicable
regulations should be fitted in-line when connecting a
pressure washer to the drinking water main. If drinking
water has passed through the backflow preventer, it can
no longer be regarded as drinking water.
