Maintenance
NOTICE:
Equipment Damage!
If the CGAM chiller evaporator or evaporator water piping is drained of water, the evaporator
immersion heater must be de-energized. Failure to de-energize the heater will cause it to burn
out.
Clean and repaint any components that show corrosion.
Clean the condenser coils. Refer to “Coil Cleaning” in this manual.
WARNING
Rotating Components!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury
Clean the condenser fans. Check the fan assemblies for proper clearance in the fan shroud
openings and for motor shaft misalignment or abnormal end-play, vibration and noise.
Compressor Service Information
Compressor Electrical Connections
It is very important that CSHD compressors used in Trane Model CGAM chillers are wired correctly
for proper rotation. These compressors will not tolerate reverse rotation. Verify correct rotation/
phasing using a rotation meter. Proper phasing is clockwise, A-B-C. If wired incorrectly a CSHD
compressor will make excessive noise, will not pump and will draw about half the normal current.
It will also become very hot if allowed to run for an extended period.
NOTICE:
Equipment Damage!
Do not “bump” the compressor to check rotation as incorrect rotation could cause compressor
motor failure in as little as 4 to 5 seconds!
It is also very important that CSHN compressors used in Trane Model CGAM chillers are wired
correctly for proper rotation. Correct rotation of CSHN compressors is also clockwise, with A-B-C
phasing. Improper rotation of the CSHN compressors is indicated by a compressor module trip,
noisy operation, no pressure difference on manifold gauges and low amp draw.
Motor Protection
Internal motor protection is provided on model CSHN compressors (15, 20, 25 and 30T sizes). LED
indicators are as follows:
•
Green — No Fault
•
Red — Fault
See
Table 64, p. 158
for fault diagnostic indications on the protection module. Manual reset is
required at the module.
