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 water inlet lter to ensure it is clean and free of any obstructions.
Periodic cleaning of the water lter will help prevent pump problems. As
a lter becomes obstructed, it restricts proper ow of water to the pump.
This can result in cavitations which will cause premature failure of pump
packings. Using a screwdriver, remove the strainer from the unit. 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.
Do not use a non-pressurized water supply (i.e. from a pond or well)
with this unit.
c. Connect the high pressure discharge hose to the water outlet of the
unit.
d. High Pressure Discharge Hose to Gun. (If Applicable)
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 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 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.)
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.
HEAT DUMP 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 running and
the trigger gun closed) for more than three minutes.
Your unit is provided with a heat dump valve. The heat dump valve will be
located opposite the water inlet on your pump. The heat dump valve 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.
