English 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. 19
