OPERATION
PRESSURE WASHER TERMINOLOGY
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc.
PSI*: Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc.
GPM*: Gallons per Minute. The unit of measure for the flow rate of water.
* Rated Pressure and Rated Water Flow is within manufacturing tolerance of
(+/- 10%).
Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is
not pulled. This feature allows the operator to release the trigger gun and reposition
themselves without having to turn the engine off in between cleaningactions.
WARNING: Do not allow the unit to run for more than two minutes without
the gun trigger being pulled. This could cause overheating and damage to
the pump. When the temperature inside the pump rises too high, the thermal
relief valve will open and release a spray of water from the pump to lower the
internal temperature. The valve will thenclose.
Thermal Relief Valve (P, Fig. 5): When the temperature inside the
5
P
pump rises too high, this valve will open and release a gush of
water in an effort to lower the temperature inside the pump. The
valve will thenclose. NOTE: Thermal relief valve location will vary
depending on the pump type.
Detergent Injection System: Mixes cleaners or cleaning solvents
with the water to improve cleaning effectiveness.
Water Supply: All pressure washers must have a source of water. The minimum
requirements for a water supply are 20 PSI and 5 Gallons Per Minute. If your water
source is a well, the garden hose length can only be 30ft. (9m) max.
WARNING: To reduce the possibility of contamination always protect
against backflow when connected to a potable watersystem.
