Recommended Maintenance
Note: Graphic labels (shown above) are used for CE
application only.
Important:
• Before servicing, disconnect all power sources and
allow at least 30 minutes for capacitors to discharge.
• All electrical enclosures—unit or remote—are IP2X.
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.
Record Keeping Forms
An important aspect of the chiller maintenance program is
the regular completion of records. Refer to
“ Forms and
Check Sheets,” p. 102
for copies of the recommended
forms. 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
of this condition.
WARNING
Hazardous Voltage w/ Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer’s
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged.
For additional information regarding the safe discharge of
capacitors, see PROD-SVB06* -EN
NOTICE:
Check Purge Run-Time for Unit Hermetic
Integrity!
If frequent purging is required, failure to monitor purge
pumpout rate, identify and correct source of air or
water leak as soon as possible could shorten chiller life
expectancy, due to moisture contamination caused by
leakage.
NOTICE:
Do Not Use Non-Compatible Parts or
Materials!
Use of non-compatible parts or materials could result in
equipment damage. Only genuine Trane
®
replacement
components with identical Trane part numbers should
be used in Trane CenTraVac chillers. Trane assumes no
responsibility for damages resulting from the use of
non-compatible parts or materials.
