Trane CenTraVac™ Water-Cooled Chiller CVHF - 190-320 - 215 - 032L / 032L

- Shut down the chiller once each year to check the items of Condenser

1. Inspect for fouling and scaling in tubes

2. Check operation of condenser water flow sensing device

3. Factory recommendation to eddy current test tubes every three years;

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

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

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

- Shut down the chiller once each year to check the items

4. Inspect motor terminal board

5. Check inlet guide vanes (IGV) for abnormalities;
