Oil Charging

Section 5 • Maintenance/Service

Oil Charging

WARNING

Avoid skin contact with oil. Wear rubber gloves and a face shield when working with oil. Failure to comply may result in serious injury or death.

1.Using a properly selected oil pump, connect oil pump to suction oil charging valve, see Figure 5-3.

2.Open suction oil charging valve and fill oil separator to Normal Operating Level.

3.Once the Normal Operating Level has been reached, shut off the oil pump and close the valve. Disconnect and remove oil pump.

CAUTION

Do not add oil to the coalescent side of the oil separator. Failure to comply may result in damage to equipment.

Normal oil level operating range must be maintained for optimum performance and to prevent damage to equip- ment. See Figure 4-1. for normal operating levels. There are a couple of ways to maintain oil, while the compres- sor unit is in operation and during shutdown.

Tool Required:

Oil Pump, Maximum 2-3 GPM with Motor approved for Division 1 or Division 2 and with ability to over- come suction pressure.

Charging During Operation:

During operation, if the oil level is low, add oil to the operating compressor through the suction oil charging valve, see Figure 5-3. Pump oil into the compressor until the oil level reaches the normal operating level. Watch this level carefully to maintain proper operation. Never allow the oil to reach a level higher than the Maximum Operating Level, since this may impair the operation and efficiency.

Charging During Shutdown:

During shutdown, if oil is to be added, charging can be performed through the drain valve located underneath the oil separator, see Figure 5-3. During shutdown, oil can be added to the Maximum Non-Operating Level. For shutdown procedure, see Compressor Unit Isolation procedure.

1.Using a properly selected oil pump, connect oil pump to oil separator drain valve.

2.Open oil separator drain valve and fill oil separator to Maximum NON-Operating Level.

3.Once Maximum NON-Operating Level has been reached, shut off oil pump, close oil separator drain valve and remove oil pump.
