INSTALLATION & PREPARATION
WATER SUPPLY:
1. 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 see-through water filter to ensure it is clean and free of any
obstructions. Periodic cleaning of the see-through water filter will help
prevent pump problems. As a filter screen 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. Unscrew the garden hose inlet connection from the front of the filter
assembly.
b. Remove the clear plastic cover and clean the filter screen.
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. In some 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.
4. 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. (A typical outdoor faucet will generally
supply this PSI if turned completely "ON".)
b. Incoming GPM must be approximately one gallon more than theoutgoing
GPM stated on the pressure 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
pumpdamage 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 ad-
justment 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 pressure washer to operate in the bypass mode (with the unit run-
ning 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.
