.
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.

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)

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).
