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 (11) 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
®
#19-0001 if necessary.
3. Connect one end of the water supply hose to the water inlet (10) of the unit.
Connect the other end of the hose to your pressurized water supply.
NOTE 1: Do not use a non-pressurized water supply (i.e. from a pond or well)
with this unit.
NOTE 2: If there is a high mineral content in your water, it is highly
recommended that an additional water strainer (Mi-T-M
®
#851-0207) be added
to the water inlet to help reduce mineral content. Clean both strainers before
starting your pressure washer.
4.
Connect the high pressure discharge hose (22) to the water outlet (13) of the
unit. Securely connect the other end of the hose to the gun assembly (23).
5.
Be certain all connections are securely tightened.
a.
Water supply hose to the Water Inlet on the unit.
b.
Water supply hose to Pressurized Water Supply.
c.
High Pressure Discharge Hose to Water Outlet on the unit.
d.
High Pressure Discharge Hose to Gun.
6.
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.
7.
Never allow the unit to operate without the incoming water line attached or
without the water supply completely turned on.
INSTALLATION & PREPARATION
UNLOADER:
1.
The unloader valve on your machine is equipped with an adjustment knob
(14) to 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!
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.
A "heat dump valve" (9) 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.
CAUTION
RISK OF UNIT DAMAGE!
DO NOT OVERTIGHTEN THE
UNLOADER. BREAKAGE COULD
RESULT IN IMMEDIATE LOSS OF
WATER PRESSURE AND COSTLY
REPAIRS.
