Periodic Maintenance

Overview

This section describes the basic chiller preventive maintenance procedures, and recommends the intervals at which these procedures should be performed. Use of a periodic maintenance program is important to ensure the best possible performance and efficiency from a CenTraVac® chiller.

Recommended purge maintenance procedures for the Purifier Purge unit are covered by PRGD-SVU01A-EN or the latest revision which can be obtained at the nearest Trane office.

Record Keeping Forms

An important aspect of the chiller maintenance program is the regular completion of records. Provided at the end of this manual are copies of the “Annual Inspection Check List and Report”, “CenTraVac with UCP Commissioning Checklist and ‘‘Start- Up Test Log’’, a ‘‘Start-Up Test Log

for Water Cooled CenTraVacs with UCP Control Panels’’ and ‘‘UCP ‘‘Settings Group’’ Menu Record’’. When filled out accurately by the machine operator, the completed logs can be reviewed to identify any developing trends in the chiller’s operating conditions.

For example, if the machine operator notices a gradual increase in condensing pressure during a month’s time, he can systematically check, then correct the possible cause(s) of this condition (fouled condenser tubes, noncondensable in the system, etcetera)

Daily Maintenance and Checks

[ ] Check the chiller’s evaporator and condenser pressures, oil tank pressure, differential oil pressure and discharge oil pressure. Compare the readings with the values provided in the Normal Chiller Operating Characteristics table.

IMPORTANT: IT IS HIGHLY RECOMMENDED THAT THE OPERATING LOG BE COMPLETED ON A DAILY BASIS.

CAUTION

Moisture Contamination!

IF FREQUENT PURGING IS REQUIRED, MONITOR PURGE PUMPOUT RATE, IDENTIFY AND CORRECT SOURCE OF AIR OR WATER LEAK AS SOON AS POSSIBLE. Failure to do so can shorten chiller life expectancy, due to moisture contamination caused by leakage.

[ ] Check the oil level in the chiller oil sump using the two sight glasses provided in the oil sump head. When the unit is operating, the oil level should be visible in the lower sight glass.
