Maintenance
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by
Trane or others, refer to the appropriate
manufacturer’s literature for allowable waiting periods
for discharge of capacitors. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
Recommended Maintenance
Weekly
While the unit is running in stable conditions:
☐ Log the chiller.
☐ Check evaporator and condenser pressures with
gauges and compare to the reading on the Tracer®
AdaptiView™ or Tracer® TU service tool. Pressure
readings should fall within operating ranges specified in
the following tables. If chiller measurements vary
significantly from values listed in the following tables,
problems may exist with refrigerant charge levels.
Contact your local Trane Service Agency.
Note: Optimum condenser pressure is dependent on
condenser water temperature, and should equal
saturation pressure of refrigerant at a
temperature 2°F to 5°F (1.1°C to 2.8°C) above
that of leaving condenser water at full load.
Monthly
☐ Review operating log.
☐ Clean all water strainers in both the chilled and
condensing water piping systems.
Annual
Contact your local Trane Service Agency to shut down the
chiller once each year and perform the following:
☐ Perform all weekly and monthly maintenance
procedures.
☐ Leak check the chiller, inspect safety controls, and
inspect electrical components, such as magnetic
bearing controller and Uninterruptible Power Supply
(UPS).
☐ Inspect all piping components for leakage and/or
damage. Clean out any in-line strainers.
☐ Clean and repaint any areas that show signs of
corrosion.
☐ Inspect vent piping of all relief valves for presence of
refrigerant to detect improperly sealed relief valves.
☐ Inspect the condenser tubes for fouling. Clean if
necessary; refer to “Cleaning the Condenser,” p. 67.
☐ Visually inspect waterbox hinges to ensure that hinges
have not been damaged or altered.
Note: If, after 10 years, the battery has not been
replaced, Trane recommends replacing the
battery.
Other
☐ Use a nondestructive tube test to inspect the
condenser and evaporator tubes at 3-year intervals.
Note: It may be desirable to perform tube tests on
these components at more frequent intervals,
depending upon chiller application. This is
especially true of critical process equipment.
Ask your Sales account manager for a copy of
engineering bulletin (CTV-PRB024*-EN) for
clarification of the role of eddy current testing in
chiller maintenance by providing information about
eddy current technology and heat exchanger
tubing.
☐ Depending on chiller duty, contact your local Trane
Service Agency to determine when to conduct a
complete examination of the unit to determine the
condition of the compressor and internal components.
Maintenance Procedures
Drive Cooling System
NOTICE
Equipment Damage!
Use of unapproved fluids, or dilution of approved
fluid, could result in catastrophic equipment damage.
Use only Trane Heat Transfer Fluid P/N CHM01023.
This fluid is a direct use concentration and is not to be
diluted. Do not top off with water or any other fluid.
Service Intervals
NOTICE
Equipment Damage!
Failure to follow instructions could result in
equipment damage.
Drive cooling fluid and strainer must be serviced
every five (5) years.
