To drain the recovered oil from the Mastercool 69100 Refrigerant Recovery System, follow these steps:
1. Check the pressure on the recovery machine's inlet pressure gauge. The pressure must be below 10 PSI (.7 Bar), but above 2 PSI (.1 Bar).
2. Insert the short yellow hose into the "plastic bottle with two openings" that is supplied with the system. Carefully attach the short yellow hose to the oil drain fitting on the recovery machine. As you tighten the hose on the fitting, oil will flow into the container.
3. Make sure to keep the neck of the bottle open to vent pressure. Do not cap the bottle neck.
4. Once the oil has completely drained, disconnect the hose from the system.
5. Unscrew the cap/hose from the bottle and dispose of the oil into an environmentally approved container.
It is recommended to drain the oil after each use of the recovery machine. The oil separator has a capacity of approximately 1.5 oz, which can cover 8-10 normal recoveries. However, some systems may deposit more oil in the separator due to high pressure or excessive oil in the system.
