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
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 af fect sprayer
performance, and chemical injector performance.
Install the appropriate spray tip on the wand (800–295
only). See Installing and Changing Spray Tips.
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 (800–412 &
800–413 only).
CAUTION
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 (800–412
& 800–413 only).
Do not exceed 20 0_F (93 _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).
Connect to Air Supply
Be sure that the air supply has a minimum flow rate equal
to the air consumption of the motor and that the pressure
is less than the maximum allowed (see Technical Data,
inside back cover).
