NOTE: When filling the water tank, DO NOT fill above the top line.
Refer to the safety decal on the tank. (Fig. 7)
NOTE: The water selector valve must be completely opened in the
Tank or Direct position before operating.
TANK FEED:
. Fill main water tank with water.
do not use detergent or
chemicals.
. Close lid.
. Turn the water selector valve to the “TANK” position when using
water from the tank. (Fig. 8)
DIRECT FEED:
. Select a water supply hose which is a quality grade of garden hose
measuring at least /4” ID and no longer than 50 feet.
2 Check the see-through water filter to ensure it is clean and free
of any obstructions. Periodic cleaning of the see-through water
filter will help prevent pump problems. As a filter screen 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. Unscrew the garden hose inlet connection from the front of
the filter assembly.
b. Remove the clear plastic cover and clean the filter screen.
(Fig. 9)
. 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. 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 that there is no feedback
of the detergents into the water supply. (Direct
connection is permitted if a back flow preventer is
installed.)
c. Quick-connect the high pressure discharge hose to the
water outlet of the unit.
d. Connect the other end of the discharge hose to the gun.
5. Turn the water selector valve to the “DIRECT” position when
using direct feed. (Fig. 0)
6. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 5 pounds per
square inch (PSI) and a maximum of 5 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 5°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 and the water supply completely turned on.
