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.
a. Using a screw driver, remove the screen from the water inlet.
b. Clean or replace with Mi-T-M
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. Connect the high pressure discharge hose to the water outlet of the
unit.
d. Securely connect the other end of the hose to the gun assembly. (A
wrench may be required on some models.)
e. Connect the wand assembly to the gun/hose assembly.
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 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:

Note: The unloader will either be adjustable or factory preset de-
pending on the model you purchased.
ADJUSTABLE:
The unloader valve 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 OVER TIGHTEN!
FACTORY PRESET:
The unloader valve on your machine is factory preset and should only be
adjusted by a trained Mi-T-M Representative. DO NOT adjust the pressure on
your own!
Adjustable
#19-0001 if necessary.
