Maintenance
The following maintenance instructions are part of maintenance operations required for this equipment. A qualifi ed
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 identifi ed and solutions found before more serious
problems arise.
Inspection visit after the fi rst 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 confi guration 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.
Caution
– Please refer to specifi c Trane documentation on oil, available from your nearest Trane offi ce. Oils recommended by
Trane have been exhaustively tested in Trane laboratories to the specifi c requirement of Trane unit and hence the
user’s requirements. Any use of oils not meeting specifi cations 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 qualifi ed 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 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.
