iNSTALLATiON & PREPARATION
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.
2
Check the water inlet strainer to ensure it isclean and free of any obstructions.
Periodic cleaning of the water strainer will help prevent pump problems. As
a strainer becomes obstructed, it restricts proper flow of water to the pump.
This can result in cavitations which will cause premature failure of pump
packings.
a. Using a screw driver, remove the screen from the water inlet.
b. Clean or replace if necessary.
3. Connect the hoses:
a. Connect one end of the water supply hose to the water inlet of the unit.
b. 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. Insome areas, the
unit 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 flow preventer is
installed.)
c. Quick-connect the high pressure discharge hose to the water outlet of
the unit.
d. Connect the other end of the discharge hose to the gun.
,
Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 25 pounds per square inch (PSI)
and a maximum of 125 PSI. (Atypical outdoor faucet will generally
supply this PSI if turned completely "ON".)
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the power washer nameplate. (You can
check GPM by timing how long it takes to fill a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive pump
damage may result if the water temperature exceeds this acceptable
level.

5. Never allow the unit to operate without the incoming water line attached and
the water supply completely turned on.
UNLOADER:
The unloader on your machine is equipped with an adjustment knob to adjust
the pressure. Should less pressure be required, simply turn the adjustment knob
counterclockwise. To set back to maximum, turn adjustment knob completely
clockwise. DO NOT OVERTIGHTEN!
THERMAL RELIEF VALVE:
To ensure the water temperature does not exceed acceptable levels, never
allow the power washer to operate in the bypass mode (with the unit running
and the trigger gun closed) for more than three minutes.
A thermal relief valve has been added to this unit to protect the pump. It may
begin to open and release water if the water temperature in the pump has
exceeded 140°F. This will allow fresh, cool water to enter the system.
