Connect to Water Supply

CAUTION

Before attaching to the water supply, check your local plumbing code regarding cross–connection to the water supply . A backflow preventer , P/N 801–133, is available to prevent backflow of contaminated water into the fresh water supply . Install it upstream from the pump.

If inlet water pressure is over 60 psi (4.1 bar) a regulating water valve, P/N 800–258, must be installed at the garden hose connection.

Do not exceed 160 _ F (70 _ C) inlet water temperature.

Connect a hose with at least a 3/4 inch (19 mm) ID from the water supply to the unit’s 3/4 inch garden hose inlet. The supply hose should not be more than 50 ft (15 m) long.

NOTE: The water source at the unit

must have a

minimum flow rate equal to that of the unit (see Technical Data, inside back cover).
