WATER SUPPLY

(Cold Water Only)



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 5/8 inch in diameter.

Flow rate of water supply must not fall below 2.5 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 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.

Do not operate pressure washer without the water turned on.
