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 strainer to ensure it is clean and free of any
obstructions. As a strainer becomes obstructed, it restricts proper
flow of water to the pump. This can result in cavitations which will
prematurely cause failure of pump packings.
a. Using a screwdriver, 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.
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 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.
WARNING
THE TRIGGER GUN SHOULD ALWAYS BE LOCKED IN THE OFF
POSITION WHEN NOT IN USE!
NOTICE
• Do not use a non-pressurized water supply (i.e. from a pond or well)
with this unit.
• 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 there is no feedback of detergents into the
water supply. (Direct connection is permitted if a back flow preventer
is installed. Check with local authorities for approval.)
• If there is a high mineral content in your water, it is highly recommended that a water softener and an additional water strainer be added
to the water inlet to help prevent the possibility of excessive scale
buildup inside the heat exchanger coil. Clean both strainers before
starting your pressure washer.

Operating Instructions
FLUSHING THE SYSTEM
This unit has a steel coil which, after setting, will cause the water remaining in the coil from the previous usage to turn brown or black. This water
must be flushed from the system before start-up. This procedure should
be performed without the high pressure hose, gun and lance assembly
installed.
1. Turn on the water supply.
2. Low pressure water will begin flowing from the water outlet. This allows the unit to flush any particles from the system. The unit is flushed
when the water is clear.
3. Once the system is flushed, turn off the water supply and connect the
high pressure hose to the water outlet of the unit.
4. Connect the trigger gun and lance assembly to the high pressure
hose.
5. Turn on the water supply.
CAUTION
BE CERTAIN THE HOSE, GUN & LANCE ASSY. ARE NOT
CONNECTED TO THE UNIT WHILE PRIMING THE PUMP. PRIMING
ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE
SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE GUN
AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.
