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.
N No otte e:: 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.
64 .
☐ Visually inspect waterbox hinges to ensure that
hinges have not been damaged or altered.
N No otte e:: 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.
N No otte e:: 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.
