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 strainer to ensure it is clean 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. Using a screw driver, remove the screen; clean or replace with
Mi-T-M #19-0001 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.
NOTE: Do not use a non-pressurized water supply (i.e. from a pond or well)
with this unit.
c. Quick-connect the high pressure discharge hose to the water outlet of
the unit.
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.
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 so you
can 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 pressure 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.
