PRESSURE WASHER TERMINOLOGY
PSI:
Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc. Sometimes noted as “Bar”, another unit
of measure.
GPM:
Gallons per Minute. The unit of measure for the flow rate of water.
CU:
Cleaning Units. GPM multiplied by psi equals CU.
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 saving to turn the engine off in between cleaning actions.
NOTICE:
Allowing the unit to run for more than two minutes without the gun
trigger being pulled could cause overheating and damage to the pump. Do not let
the pressure washer run for more than two minutes in Bypass Mode. Turn off the
engine and relieve the pressure in the gun during these extended situations.
Thermal Relief Valve (P):
When the temperature inside the 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
then close.
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 30 ft. (9 m) max.
