Trane CenTraVac™ Water-Cooled Chiller CVHE - 230-320 - 233 - 032S / 032S

Inlet guide vane linkage checked?

Painted surfaces cleaned and touched-up as needed?

Deteriorated, torn, or missing insulation repaired?

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

Sign off on the tube maintenance

Upload the purge Installation, Operation, and Maintenance manual

Follow maintenance and/or inspection items identified in the manual

Review overall operation of purge

Sign off on the purge unit inspection

Warning: Equipment Damage! Failure to follow instructions could result in equipment damage

Do NOT use Teflon-based tape or paste on anode; a small amount of liquid sealant (Loctite® 242 or equivalent) may be applied to prevent leakage when installing an anode, but do not apply so much sealant that it prevents the necessary electrical connection between the anode and the waterbox

Inspection of anodes for wear within the first several months of the anodes being placed into service

Enter the observed loss of anode material

Anode has lost 50 percent or more of its original mass

If anode depletion occurs very quickly, was a water treatment specialist consulted?

Upload a photo of the anode after inspection

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.
