Trane CenTraVac™ Water-Cooled Chiller CVHF - 350-910 - 957 - 080L / 142L

Shut down the chiller once each year to check the items of Control Circuits

Test appropriate sensors for accuracy

Ensure sensors are properly seated in wells with thermopaste installed

Check evaporator leaving water temperature low temperature cutout setpoint

Condenser high pressure switch check-out

Check adjustment and operation of the inlet guide vane actuator

Sign off on the control circuits inspection

Use a non-destructive tube test to inspect the condenser and evaporator tubes

Tube test performed on condenser and evaporator tubes?

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

Trane recommends that coated waterboxes/tubesheets - regardless of the type of protective coating included - be taken out of service within the first one to three months of operation for inspection.

Any voids or defects identified upon inspection?

If voids or defects are identified, they must be repaired.

Is the water quality known to be highly supportive of corrosion (i.e., sea water, etc.)?

If yes, inspect the coating system at one month.

Is the water quality known to be relatively benign (i.e., normal treated and clean condenser water)?

If yes, inspect the coating system within three months.

Did the initial inspections show no problems?

Only when initial inspections show no problems are present should subsequent maintenance intervals be increased.

Review the purge Installation, Operation, and Maintenance manual and follow maintenance and/or inspection items identified

Review overall operation of purge and service as necessary
