HLP-SERIES Hot Water Pressure Washer Operator's Manual
installation instructions
HiGH pressure connection:
Connect the high pressure discharge hose by connecting one end to the
pressure washer and the other end to the gun assembly. Make certain the
quick connects are securely locked together.
Water supply:
. Select a water supply hose which is a quality grade of garden hose
measuring at least 3/4" ID and no longer than 50'.
2. Connect one end of the water supply hose to the water inlet of the unit.
Connect the other end of the hose to your pressurized water supply.
NOTE:
If there is a high mineral content in your water, it is recommended
that a water softener be used to prevent the possibility of excessive
scale buildup inside the heat exchanger coil.
3. Be certain all connections are securely tightened.
a. Water supply hose to the Water Inlet on the unit.
b. Water supply hose to the Pressurized Water Supply.
4. Follow the incoming water requirements listed below:
a. Water pressure must be between a minimum of 20 pounds per
square inch (PSI) and a maximum of 65 PSI.
b. Incoming GPM must be approximately one gallon more than
the outgoing GPM stated on the pressure washer I.D. Plate.
(You can check GPM by timing how long it takes to fill a 5 gallon
container.)
c. Incoming water temperature must not exceed 25°F. Excessive
pump damage may result if the water temperature exceeds this
acceptable level.
NOTE:
If the water supply is inadequate or the hose is kinked, the unit will
run rough and the burner will not fire.
5. Never allow the unit to operate without the incoming water line attached
and the water supply completely turned on.
