Check for Shipping Damage
The unit should be checked for any damage that may have occurred in shipping. Any damage should be noted and the carrier notified immediately.
Set Up
If you are using a downstream chemical injector, install it between the pump unloader and the high pressure hose, using the quick couplers provided.
Connect the high pressure hose between the pump outlet and the gun inlet. Both of these connections are made with quick couplers.
CAUTION
Up to 100 ft (30 m) of high pressure hose may be used. Longer hoses may affect sprayer performance, and chemical injector performance, if used.
Install the appropriate spray tip on the wand. See Installing and Changing Spray Tips. If you are using a sandblaster kit, see its separate manual for installation instructions.
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).
