5.Open the drain located on the shell of the cooler/®lter. Run a hose from the drain to a bucket to catch the oil.

6.Once the pressure has been relieved and the oil drained, loosen the bolts that hold the cover on the ®lter body. Remove the old ®lter cartridges and replace with a new ®lter cartridge. Assemble the ®lter assembly (®lters, spacer, and stopper assembly), and make sure that the spring is centered against the ®lter assembly as shown in Fig. 44.

7.Replace the drain ®tting, using standard practices to en- sure a leak-tight joint. Evacuate the air from the cooler/ ®lter assembly.

8.Once the assembly has been evacuated, open the isola- tion valves.

9.Connect power to the oil heater and oil pump. The oil heater should turn on and warm the oil to 140 to 150 F (60 to 66 C). Operate the oil pump for 2 minutes. Add oil, if required, to keep the level up in the lower sight glass.

Oil should be visible in the reservoir sight glass during all operating and shutdown conditions.

EXTERNAL GEAR OIL FILTER Ð Change the oil ®lter annually or whenever the chiller is open for repairs. The 17EX external gear lubrication system has an isolatable ®lter. Use the following procedure.

1.Make sure that the compressor is off and the compressor disconnect is open.

2.Disconnect the power to the oil heater, if equipped, and to the oil pump.

3.Close the line valves to the ®lter.

4.Relieve any pressure from within the ®lter by using the pressure connection on the oil feed line valve to the com- pressor. Run a hose from the connection to a bucket to catch the oil.

5.Open the drain located on the shell of the cooler/®lter. Run a hose from the connection to a bucket to catch the oil.

6.Once the pressure has been removed and the oil drained, loosen the bolts that hold the cover on the ®lter body. Remove the oil ®lter cartridges and replace with new car- tridges. Assemble the ®lter assembly (®lters, spacer, and stopper assembly), and make sure that the spring is cen- tered against the ®lter assembly, as shown in Fig. 44.

7.Replace the drain ®tting, using standard practices to en- sure a leak-tight joint.

8.Open the isolation valves.

9.Connect power to the oil heater, if equipped, and oil pump. Operate the oil pump for 2 minutes. Add oil, if required, to keep the level up in the sight glass.

Oil should be visible in the reservoir sight glass during all operating and shutdown conditions.

Oil Speci®cations Ð If oil is to be added, it must meet the Carrier speci®cations shown in Table 11.

Oil Changes Ð Carrier recommends changing the oil after the ®rst year of operation and every three to ®ve years thereafter as a minimum. Carrier also recommends a yearly oil analysis. However, if a continuous oil monitoring system is functioning and a yearly oil analysis is performed, the time between oil changes can be extended.

COMPRESSOR OIL

1.Open the control and oil heater circuit breaker.

2.Drain the oil reservoir by opening the oil charging valve, (Fig. 2, Item 22). Slowly open the valve against refrig- erant pressure.

3.Change the oil ®lter at this time. See the Changing the Oil Filters section, page 76.

4.Charge the chiller with approximately 20 gallons (76 L) of oil for FX (size 531-599) style compressors in order to bring the level to the middle of the upper sight glass (Fig. 2, Item 21). Turn on the power to the oil heater and let the PIC warm it up to at least 140 F (60 C). Operate the oil pump manually, through the control test, for 2 min- utes. The oil level should be between the lower sight glass and one-half full in the upper sight glass for shutdown conditions.

EXTERNAL GEAR OIL Ð Proper lubrication is vital to maintain gear drive performance. After 500 hours or 4 weeks of initial operation, whichever is ®rst, the external gear drive should be thoroughly drained, ¯ushed, and re®lled with the proper lubricant. Under normal operating conditions, the lu- bricant should be changed every 2500 hours or 6 months, whichever comes ®rst. This change frequency can be ex- tended if an oil sample analysis indicates a very limited deg- radation or contamination.
