INSTALLATION & PREPARATION
ADJUSTABLE PRESSURE DUAL LANCE:
This unit features an Adjustable Pressure Dual Lance which allows the user
to select a high or low pressure "fan" spray. Simply rotate the adjustable grip
on the dual lance to achieve the desired pressure selection.
1. Selection of high pressure can be achieved by turning the adjustable grip
on the Dual Lance assembly counterclockwise as shown in the figure
below.
2. Selection of low pressure can be achieved by turning the adjustable grip
on the Dual Lance clockwise as shown in the figure below.
DUAL LANCE CONNECTION:
1. Be certain the trigger gun is locked in the "OFF" position.
2. Connect the dual lance assembly to the trigger gun assembly at this time
(if applicable). Be certain the connection is securely tightened.
NOZZLE CONNECTION:
1. Be certain the trigger gun is locked in the "OFF" position. (See WARNING,
right.)
2. Connect the lance assembly to the trigger gun assembly at this time.
Be certain the connection is securely tightened.
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.
NOTE 1:
Do not use a non-pressurized water supply (i.e. from a pond or
well) with this unit.
NOTE 2:
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 backflow preventer is installed. Check with local authorities
for approval.)
NOTE 3:
If there is a high mineral content in your water, it is highly
recommended that a water softener and an additional water
strainer (#851-0207) 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.
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 is completely turned on.
