The Model 940-220 Powerig® Hydraulic Unit is a portable, electrically operated power source designed to operate all Huck hydraulic installation equipment excluding HUCK-SPIN tools. The Powerig Hydraulic Unit requires 15 amp (minimum) circuit with a common wall outlet. An electrical enclosure contains a motor, contactor, a transformer, a relay and a circuit breaker. Hydraulic pressure is developed by a two-stage, gear-piston pump driven by a 1-1/8 horsepower universal electric motor. Pressurized fluid is directed by a four-way directional valve to either the PULL port or the RETURN port of the installation equipment. The four-way directional valve is operated by a 24 volt AC control circuit. The high pressure relief valve controls PULL pressure (maximum pressure of the unit) and is adjustable by the operator. An internal relief valve is preset at the factory to protect the operator and equipment. The internal relief is not adjustable by the operator. A pressure switch controls RETURN pressure and turns off the Powerig Hydraulic Unit at the end of an installation cycle. Pressures are adjustable to match Huck equipment being used. See applicable tool instruction manual for pressure settings for other Huck installation equipment. Hydraulic fluid is stored in the reservoir which also serves as the base. Remove the filler cap/dipstick to check fluid level and to add fluid. Hydraulic quick disconnect couplers are furnished for connecting hoses from installation equipment.
