Trane CenTraVac™ Water-Cooled Chiller CVHE - 360-500 - 455 - 080L / 080L

Shut down the chiller once each year to check the items of Starter or Adaptive FrequencyTM Drive

Check all connections per manufacturer specifications

Follow all manufacturer recommendations for starter or Adaptive FrequencyTM Drive (AFD) maintenance

Inspect/clean/service the AFD cooling system (water- or air-cooled AFD)

Record all applicable starter or starter component settings

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.

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

Anodes inspected for wear within the first several months of service?

Enter the observed loss of anode material in percentage

Anode replaced if it has lost 50 percent or more of its original mass?

Was a water treatment specialist consulted if anode depletion occurred very quickly?

Upload a photo of the installed anode

Equipment Damage! Mixing refrigerants or oils could result in equipment damage including bearing damage, introduction of acids into the chiller, or continuous purge pump-out in high-head/high ambient applications

CenTraVac chillers are manufactured with different refrigerant/oil systems: 1) chillers using R-123 refrigerant and OIL00022 compressor oil, and 2) chillers using R-514A refrigerant and OIL00334/OIL00335 compressor oil

Verify proper refrigerant and oil for your chiller and do NOT mix refrigerants or oils!

Important: Verify proper refrigerant and compressor oil for your chiller before proceeding!

1. After the first six months of accumulated operation or after 1000 hours operation—whichever comes first—it is recommended to change the oil and filter

2. After this oil change, it is recommended to subscribe to the Trane annual oil analysis program rather than automatically change the oil as part of scheduled maintenance

3. Change the oil only if indicated by the oil analysis. Using an oil analysis program will reduce the chiller’s overall lifetime waste oil generation and minimize refrigerant emissions. The analysis determines system moisture content, acid level, and wear metal content of the oil, and can be used as a diagnostic tool. The oil analysis should be performed by a qualified laboratory that is experienced in refrigerant and oil chemistry and in the servicing of Trane® centrifugal chillers

Inspect for fouling and scaling in tubes

Check operation of evaporator water flow sensing device

Factory recommendation to eddy current test tubes every three years
