Trane CenTraVac™ Water-Cooled Chiller CVHF - 350-570 - 588 - 080S / 080S

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

1. It may be desirable to perform tube tests on these components at more frequent intervals depending upon chiller application

2. This is especially true of critical process equipment

3. 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;

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

4. Inspect motor terminal board

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

WARNING: Explosion Hazard! Never use an open flame to detect gas leaks. Use a leak test solution for leak testing.

WARNING: Hazardous Pressures! If a heat source is required to raise the tank pressure during removal of refrigerant from cylinders, use only warm water or heat blankets to raise the tank temperature. Do not exceed a temperature of 150°F. Do not under any circumstances apply direct flame to any portion of the cylinder.

Check purge times and unit performance logs

Submit refrigerant sample for analysis if required

Inspect unit for any signs of refrigerant or oil leakage

Check unit for any loose screws on flange, volutes, or casing

- Operate the tang operators manually and check for any abnormalities

- Drain contents of the rupture disk and purge discharge vent-line drip-leg into an evacuated waste container

- Do this more often if the purge is operated excessively

- Apply oil to any exposed metal parts to prevent rust;

Lubricate the vane control linkage bearings, ball joints, and pivot points

Lubricate vane operator tang O- rings

Lubricate the oil filter shutoff valve O-rings
