Important Technical Specifications

Operating pressure: 1350 PSI (Pounds per Square Inch)
Water volume: 1.3 GPM (Gallons per Minute)
Voltage: 120 V
Amp draw: 14 AMPS
Water supply: The water hose must be at least 3/4 inch in diameter. The flow rate of the water supply must not fall below 2.5 GPM. The flow rate can be determined by running the water for one minute into an "empty" 5-gallon container. The water supply temperature must not exceed 104°F/40°C.
GFCI (Ground Fault Circuit Interrupter): The unit is equipped with a GFCI for electrical safety, which should be plugged into a working outlet.
Extension cords: If an extension cord is necessary, it must be a 3-wire grounded cord with a GFCI. For lengths up to 25 ft, use 12/2 gauge. For lengths up to 50 ft, use 10/2 gauge. Extension cords should be suitable for outdoor use, marked "Acceptable for use with outdoor appliances," and kept away from water.
