INSTALLATION & PREPARATION
INSTRUCTIONS
Nozzle connection
Be certain the trigger gun is locked in the “OFF” posi-
tion.
The nozzle assembly should be disconnected from
the gun/wand assembly at this time by retracting the
locking ring on the quick-connect tting to remove the
nozzle.
Water supply
Select a water supply hose which is a quality grade of
garden hose measuring at least 3/4” ID and no longer
than 50 feet.
Check the water inlet strainer to ensure it is clean and
free of any obstructions. Periodic cleaning of the water
strainer will help prevent pump problems.
NOTICE
As a strainer becomes obstructed, it restricts proper
ow of water to the pump. This can result in cavita-
tions which will cause premature failure of pump
packings.
1. Unscrew the garden hose inlet connection from the
front of the lter assembly.
2. Remove the clear plastic cover and clean the lter
screen.
Connect the hoses.
1. Connect one end of the water supply hose to the water
inlet of the unit.
2. Connect the other end of the hose to your pressurized
water supply. When connecting the water inlet to
the water supply mains, local regulations of your
water company must be observed. In some areas,
the unti must not be connected directly to the public
drinking water supply. This is to ensure that there is
no feedback of the detergents into the water supply.
(Direct connection is permitted if a back ow preventer
is installed.
3. Quick-connect the high pressure discharge hose to the
water outlet of the unit.
4. Connect the other end of the discharge hose to the
gun assembly.
Follow the incoming water requirements listed below:
1. Water pressure must be a minimum of 25 pounds per
square inch (PSI) and a maximum of 125 PSI. (A typical
outdoor faucet will generally supply this PSI if turned
completely “ON”.)
2. Incoming GPM must be approximately one gallon more
than the outgoing GPM stated on the pressure washer
nameplate. (You can check GPM by timing how long
it takes to ll a 5 gallon container.)
NOTICE
Incoming water temperature must not exceed
145°F. Excessive pump damage may result if the
water temperature exceeds this acceptable level.
NOTICE
Damage to the equipment could occur. Never allow
the unit to operate without the incoming water line
attached and the water supply completely turned on.
