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 flow rate of water
CU: Cleaning units.gpm multiplied by psi
Bypass Mode: In bypass mode;the pump is recirculating water because the
trigger of the spray gun is not pulled. If unit is left in bypass mode for more than
two(2)minutes, the water temperature will rise to a dangerous level and could
damage internal components of the pump.Any damage to pump due to these
causes will not be covered under warranty.
Do not allow unit to operate in bypass mode for more than two
minutes at any time. Overheating of pump can cause damage to pump.
Thermal Relief Valve: In an effort to prevent extreme damage,pumps are
equipped with a thermal relief valve. This valve will open when the temperature
inside the pump rises too high. This valve will then release a gush of water in an
effort to lower the temperature inside the pump.Immediately after this occurs, the
valve will close.
Chemical Injection System: Mixes cleaners or cleaning solverts with the
pressurized water to improve cleaning effectiveness.
Water Supply:All pressure washers must have a source of water. the minimum
requirements for a water supply are 20PSI and 5gallon per minute.
