Oil Maintenance

Compressor Oil Change

It is recommended to change the oil and oil filter:

After the first 1000 hours of chiller operation. For a chiller operated continuously this oil and oil filter change may be performed as soon as 1.5 months after first start-up, for a chiller operated intermittently it may be 4 or 6 months after first start-up.

Again at the first scheduled annual mainenance, preferably within 6 to 12 months of the first oil change.

Note: Use only Trane OIL00022. A full oil change is 9 gallons of OIL00022.

Beyond the first year, recommendations are to subscribe to an annual oil analysis program rather than automatically change the oil as part of scheduled maintenance. Change the oil only if indicated by the oil analysis. Use of an oil analysis program will reduce the chillers overall lifetime waste oil

generation and minimize refrigerant emissions. The oil analysis should be performed by a qualified laboratory that is experienced in refrigerant and oil chemistry and in the servicing of Trane centrifugal chillers.

In conjunction with other diagnostics performed by a qualified service technician, oil analyses can provide valuable information on the performance of the chiller to help minimize operating and maintenance costs and maximize it’s operating life. A drain fitting is installed in the oil filter top, after the oil filter, for obtaining oil samples.

Oil Change Procedure

When oil analysis indicates the need to change compressor oil, use the following procedure for removing oil.

CAUTION

Heater Damage!

The oil sump heater must be deenergized before draining the sump. Failure to do so could possibly burn out the oil sump heater.

[ ] Draw the oil from the chiller through the oil charging valve on the chiller oil sump into an approved, evacuated tank; or,

[ ] Pump the oil from the chiller through the oil charging valve into an airtight resealable container, using a magnetically-driven auxiliary pump.

Forcing the oil from the oil sump by pressurizing the chiller (by raising chiller temperature or adding nitrogen) is not recommended.

Refrigerant dissolved in the oil can be removed and returned to the chiller by using an appropriate deep- vacuum recovery unit and heating and agitating the oil container. Follow all Federal, State and Local regulations with regard to disposal of waste oil.
