Pressure Relief Procedure
10 333031E
Nozzle Connection
1. Perform Pressure Relief Procedure, page 8.
2. Engage trigger lock.
3. The nozzle assembly should be disconnected from
the gun/wand assembly at this time by retracting the
locking ring on the quick-connect fitting to remove
the nozzle.
Water Supply
Select a water supply hose which is a quality grade of
garden hose measure at least 3/4 in. (19.05 mm) ID and
no longer than 50 feet (15.24 m).
Check the water inlet strainer to make sure it is clean
and free of any obstructions. Periodic cleaning of the
water strainer will help prevent pump problems.
1. Unscrew garden hose inlet connection from front of
filter assembly.
2. Remove clear plastic cover and clean filter screen.
Connect the hoses
1. Connect one end of water supply hose to water inlet
of unit.
2. Connect other end of hose to pressurized water
supply. When connecting water inlet to water supply
mains, local regulations of your water company
must be observed. In some areas, the unit must not
be connected directly to public drinking water sup-
ply. This prevents feedback of the detergents into
the water supply. Direct connection is permitted if a
back flow preventer is installed.
3. Quick-connect high pressure discharge hose to
water outlet of unit.
4. Connect other end of discharge hose to gun assem-
bly.
Follow incoming water requirements listed below:
1. Water pressure must be a minimum of 25 psi (0.17
MPa,1.72 bar) and a maximum of 125 psi (0.86
MPa, 8.6 bar). NOTE: A typical outdoor faucet will
generally supply this psi if fully turned on.
2. Incoming GPM must be at least one gallon more
than the outgoing GPM stated on pressure washer
nameplate. NOTE: You can check GPM by timing
how long it takes to fill a 5 gallon container. NOTICE
As a strainer becomes obstructed, it restricts proper
flow of water to the pump. This can result in cavitation
which will cause premature failure of pump packings.
NOTICE
Incoming water temperature must not exceed 140° F
(60° C). Excessive pump damage may result if the
water temperature exceeds this acceptable level.
Never allow the unit to operate without the incoming
water line attached and the water supply fully turned
on. Damage to the equipment could occur.
