Check for Shipping Damage

Check the unit for any damage that may have occurred in shipping. Note any damage and notify the carrier immediately.

Set Up

Before plugging in the unit, be sure the electrical service matches the specification in Technical Data (inside back cover) and the voltage label on the unit. With the unit off, plug the power supply cord into a grounded, GFCI-protected outlet. Do not remove the electrical plug which comes with the unit or bend connecting prongs to fit an improper outlet! Use an extension cord that meets the requirements of the EXTENSlON CORD section and is no more than 100 ft (30 m) long. Added length of cord will affect current draw of unit.

Connect the high pressure hose between the pump outlet and the gun inlet.

CAUTION

Up to 100 ft (30 m) of high pressure hose may be used. Longer hoses may affect sprayer r- performance, and chemical injector performance.

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.

Install a regulating water valve, P/N 800-258, if inlet water pressure is over 60 psi (4.1 bar).

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

Connect a hose with at least a 3/4 inch (19 mm) ID and not longer than 50 ft (15 m) to the unit’s 3/4 inch garden hose inlet.

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).
