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
• 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.
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 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 55°C to clean condenser
coils. The resulting increasing
pressure could cause refrigerant
lost through the safety valve.
