Maintenance Instructions
The following maintenance
instructions are part of maintenance
operations required for this
equipment. A qualified technician is
needed for regular maintenance as
part of a regular maintenance
contract.
Carry out all operations as required
by schedule. This will insure long
unit service life and reduce the
possibility of serious and costly
breakdown.
Keep service records up to date,
showing monthly information on
unit operations.
These records can be of great help
to maintenance personnel
diagnostics. Similarly, if machine
operator keeps a log of changes in
unit operating conditions, problems
can be identified and solutions found
before more serious problems arise.
Inspection visit after the first 500
hours of operation from unit start up
- Carry out oil analysis.
- Carry out leak test.
- Inspect contacts and tighten
terminals.
- Record operating pressures,
temperatures, amperages and
voltage.
- Check operation of
machines/compare conditions of
operation against original
commissioning data.
- Fill out inspection visit log sheet
and review with the operator.
Monthly preventive visit
- Carry out leak test.
- Oil test of acidity.
- Inspect contacts and tighten
terminals.
- Record operating pressures,
temperatures, amperages and
voltage.
- Check operation of machines/
compare conditions of operation
against original commissioning
data.
- Fill out visit log sheet and review
with the operator.
Annual preventive visit
- Check operational set points and
performance.
- Calibrate controls.
- Check operation of all safety
devices.
- Inspect contacts & tighten
terminals.
- Megger the motor compressor
windings.
- Record operating pressures,
temperatures, amperages and
voltage.
- Carry out leak test.
- Check configuration of unit control
module.
- Carry out oil analysis
- Change the oil as required based

Caution
- Please refer to specific Trane
documentation on oil, available
from your nearest Trane office.
Oils recommended by Trane have
been exhaustively tested in Trane
laboratories to the specific
requirement of Trane chiller and
hence the user’s requirements.
Any use of oils not meeting
specifications recommended by
Trane is the responsibility of the
user only, who thereby is liable to
warranty loss.
- Oil analysis and oil test acidity
must be carried out by a qualified
technician. Poor interpretation of
results may cause unit operating
problems. Also, oil analysis must
follow the correct procedures, to
avoid accidental injury to
maintenance personnel.
- If the condensers are dirty, clean
them with a brush. If the coils are
too dirty, consult a cleaning
professional. Never use water to
clean condenser coils.
- Contact Trane ServiceFirst for
information on maintenance
contracts.
Warning
- Switch off unit main power supply
before to any intervention. Failure
to follow this safety instruction can
lead to accident death of the
maintenance personnel and may
also destroy equipment.
- Never use steam or hot water
above 55°C to clean condenser
coils. The resulting increasing
pressure could cause refrigerant
loss through the safety valve.
