Check for Shipping Damage
Check
the unit for any
damage that may have occurred
in shipping. Notify the carrier immediately if there is
any
damage.
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).
