Nozzle connection

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 fitting 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 flow 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 filter assembly.

2.Remove the clear plastic cover and clean the filter 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 flow 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 fill 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.
