Glossary

• Bypass mode : Allows water to re-circulate within the 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 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.
