PRESSURE WASHER TERMINOLOGY
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 fl ow rate of water.
CU:
Cleaning Units. GPM multiplied by PSI. GPM x PSI = CU
Bypass Mode:
Allows water to re-circulate within the pump when the gun trigger is not pulled.
C A U T I O N
Allowing the unit to run for more than two minutes without the gun trigger pulled could cause overheating and damage to the
pump.
