Maintenance

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

- Check that the condenser pressure

drop and air flow conforms to
start-up measurements.

Monthly preventive visit
- Carry out leak test.
- Oil test of acidity
- Check Ethylene glycol % in the

chilled water circuit if glycol
presence is required

- 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 water flows and interlocks.
- Check Ethylene glycol % in the

chilled water circuit if glycol
presence is required

- Check operational set points and

performance.

- Calibrate controls.
- Check operation of all safety

devices.

- Inspect contacts and 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

upon results of the oil analysis

- Check operation of

machines/compare conditions of
operation against original
commissioning data.

- Fill out the annual start up visit log

sheet and review with the
operator.

- Check that the condenser pressure

drop and air flow conforms to
start-up measurements.

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 brush. If the coils are
too dirty, consult a cleaning
professional. Never use water to
clean condenser coils.

- Contact Trane 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
lost through the safety valve.
