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 ensure 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 aintenance 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 and clean the strainer
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
• Check and clean the water strainer
Annual preventive visit
• Check water flows and interlocks
• Check expansion tank pressure
• Check glycol % in the chilled water circuit if glycol
presence is required
• Check operational setpoints and performance
• Calibrate controls and pressure transducer
• 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 and clean the water strainer
CAUTION!
• 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 soft
brush and water. If the coils are too dirty, consult a
cleaning professional. Never use high pressure water
to clean condenser coils.
• Contact Trane Service 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 60°C to clean
condenser coils. The resulting increasing pressure
could cause refrigerant lost through the safety valve.
