Maintenance
Annual preventive visit
• Check water flows and interlocks
• Check expansion tank pressure
• Check glycol concentration in
the chilled water circuit if glycol
presence is required
• Check operational set points 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 strainer
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,
(Remote condensers) 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 injury or death of the maintenance
personnel and may also damage
equipment.
CAUTION:
Never use steam or
hot water above 60°C to clean
condenser coils (Remote condensers).
The resulting increasing pressure
could cause refrigerant loss through
the safety valve.
