1. Compressor Not Running

Fan is running. Power switch is ON.

• Float is not attached to tank. Attach float cable.
• Tank is full and needs changed with a new (empty) tank.
• Red high pressure cutout light on control panel is ON, indicating too much pressure in tank. Replace tank.
• Turn off unit. Turn both Valve 1 and Valve 2 to the Equalize position to equalize pressure. Attempt restart.

2. Refrigerant Not Moving

Compressor is running.

• Liquid tank valve not open. Open Liquid tank valve.

Compressor is running. Valves in correct position

• Faulty manifold connections. Verify connections.
• Internal leak in ball valves. Test for leaks.
• Bad compressor. Replace

3. Slow Recovery

• Recovery is faster when the tank pressure and/or the amount of refrigerant in the tank is low. If recovery begins to slow; switch to an empty tank, a cooler tank, or one with less refrigerant in it.
• If the system has isolated pockets of liquid, the only way to remove them is evaporation. To speed recovery, try using a heat gun to help boil the refrigerant out of these pockets.
