Maintenance
Pump maintenance
Pumps motor bearings and mechanical seals have
a designed life expectancy of 20000-25000 hours of
operation. For critical applications it might be necessary
to change the components as a preventive measure.
Compressors Service Information
Oil Equalizer line
CSHD Compressors
The oil equalizer line is equipped with a Rotolock tting
for easy removal. Torque value for tightening these
tting is 90 N.m. Before removing the oil equalizer line,
the system refrigerant charge must be recovered before
draining the oil. Use a catch pan to catch the oil when
the compressor oil equalizer line is loosened to ensure
that oil does not spill out of the compressor when the
equalizer line is removed.
Tandem and Trio Compressor Suction Restrictors
Since most uneven tandem and trio compressor sets
require the use of a restrictor in the suction line of one
or more compressors in order to provide correct oil level
balance between compressors when they are operating.
Compressor Replacement
If the CGAX/CXAX chiller suffers a failed compressor,
use these steps for replacement:
Each compressor has lifting eyes. Both lifting eyes must
be used to lift the failed compressor. DO NOT LIFT A
COMPRESSOR USING A SINGLE LIFTING EYE. Use
proper lifting techniques, a spreader bar and rigging as
for lifting both compressors simultaneously.
Compressor weights by compressor model are:
DSH 092 – 58 kg.
DSH 125 – 64 kg.
DSH 142 – 67 kg.
DSH 161 – 69 kg.
DSH 183 – 76 kg.
After a mechanical failure of a compressor, it
is necessary to change the oil in the remaining
compressor and also replace the liquid line lter
drier. After an electrical failure of a compressor, it will
also be necessary to change the oil in the remaining
compressor, replace the liquid line lter drier and add a
suction lter drier with cleanup cores.
Note: Do not alter the refrigerant piping in any way as
this can affect compressor lubrication.
Note: Do not add a suction lter drier within 250mm of
the elbow for CSHD compressors.
Refrigerant System Open Time
Model CGAX/CXAX chillers use POE oil (Trane
recommended oil OIL 048E or OIL 023E) and therefore
refrigerant system open time must be kept to a
minimum. The following procedure is recommended:
• Leave a new compressor sealed until it is ready to
be installed in the unit. Maximum system open time
is dependent upon ambient conditions, but do not
exceed one hour open time.
• Plug the open refrigerant line to minimize moisture
absorption. Always change the liquid line lter drier.
• Evacuate the system to 500 microns or below.
• Do not leave POE oil containers open to the
atmosphere. Always keep them sealed.
Mechanical Compressor Failure
Replace the failed compressor(s) and change the oil in
the remaining compressor(s) along with the refrigerant
system liquid line lter drier.
Electrical Compressor Failure
Replace the failed compressor and change the oil in
the other compressor(s). Also add a suction lter with
cleanup cores and change the liquid line lter drier.
Change lters and oil until the oil no longer test acidic.
See “Oil Testing.”
Compressor Motor Megging
Motor megging determines the electrical integrity of the
compressor motor winding insulation. Use a 500 volt
megger. A less than 1 meg-ohm reading is acceptable
and 1000 ohms per nameplate volts is required to safely
start the compressor.
Compressor Current Imbalance
Normal current imbalance could be 4 to 15 percent
with balanced voltage due to motor design. Each phase
should register .3 to 1.0 ohms and each phase should
be within 7 percent of the other two phases. Phase to
ground resistance must be innity.
Note: Maximum allowable voltage imbalance is
2percent.
