Setup Instructions Operating Guidelines • The voltage at the unit must be ±10% of the unit’s rated voltage. • Extension cords must be a minimum of 14 AWG and kept as short as possible. • To minimize mixing of refrigerants, the self-clearing procedure must be performed after each recovery operation. • The low-side gauge on the unit allows you to monitor system pressure and stop recovery when a deep enough vacuum has been reached. The high-side gauge allows you to monitor the refillable tank pressure.

Operating Instructions Recovery Procedure WARNING To prevent personal injury, Read and follow all warnings at the beginning of this manual before operating the unit. Wear safety goggles when working with refrigerants. Use only authorized refillable refrigerant tanks. Disconnect hoses using extreme caution. All hoses may contain refrigerant under pressure. 1. Connect hoses as described in the Setup Instructions. 2. Open the LIQUID and VAPOR valves on the recovery tank. Open the ball valves on all four hoses.
Operating Instructions WARNING The refrigerant level in the tank must not exceed 80% of the tank volume. Failure to monitor the level could result in excessive hydrostatic pressures, causing physical injury or death. tank-to-tank transfer When recovering refrigerant from one refillable tank into another, the color of the hoses used for SYSTEM LIQUID and SYSTEM VAPOR may not match the color of the liquid and vapor valves on the tank you are pulling the refrigerant from.
Operating Instructions Self-Clearing Procedure CAUTION! Do not mix refrigerant types. Always perform the selfclearing procedure after each recovery. Beginning each job with a “clean” unit will help eliminate mixing of different refrigerant types. 1. Close the ball valves on the red and blue hoses connected to the A/C-R system. Disconnect these hoses from the system’s access ports. 2. Close the blue LIQUID valve on the tank and the ball valve on the blue TANK LIQUID hose.
Maintenance This unit has been designed for minimal maintenance. The compressor should be evaluated for wear after 2,500 hours of use. Call Robinair’s Technical Support Line, (800) 822-5561, for the location of an authorized Robinair service center near you.
Troubleshooting Tips Compressor does not start Problem: Compressor circuit breaker has tripped. Solution: Depress the circuit breaker switch. Problem: HIGH PRESSURE light is on. Solution: The high side pressure switch has tripped; verify the tank and hose ball valves are open. Check tank and verify it is not full. Problem: Power switch is not on. Solution: Press the power switch to ON. Compressor runs but does not move refrigerant Problem: The ball valves on the hoses are not open.
