Glossary

Bypass mode: Allows water to re-circulate within pump when the gun trigger is not pulled.

chemical hose: Feeds cleaning agents into the pump to mix with the water. Refer to chemicals and cleaning solvents.

chemical injection system: Mixes cleaners or cleaning solvents with water to improve cleaning effectiveness.

choke control: Opens and closes carburetor choke valve.

cu: Cleaning Units. GPM multiplied by psi. (GPM x PSI = CU)

Fuel valve lever: Opens/closes connection between fuel tank and carburetor.

GPM: Gallons Per Minute. The unit of measure for the flow rate of water.

PsI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc.

kPa (kilopascal): Metric pressure measurement. 1 kilopascal equal 1000 pascals.

Quick-connect spray wand: Allows the user to quickly change out high-pressure nozzles. Refer to spray Wand nozzles.

thermal relief valve: When the temperature inside the pump rises too high the valve will open and release a gush of water in an effort to lower the temperature inside the pump. The valve will then close.

Water supply: All pressure washers must have a source of water. The minimum requirements for a water supply are 20 psi (138 kPa) and 5 gallons per minute.
