Trane CenTraVac™ Water-Cooled Chiller CVHF - 350-570 - 588 - 050L / 050L

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

2. Clean and touch-up painted surfaces as needed

3. Repair deteriorated, torn, or missing insulation;

- Shut down the chiller once each year to check the items for Leak Test Chiller

1. Check purge times and unit performance logs. If warranted, pressure leak test

2. Review oil analysis. If required, submit refrigerant sample for analysis

3. Inspect unit for any signs of refrigerant or oil leakage

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

Failure to follow safe leak test procedures below could result in death or serious injury or equipment or property-only-damage

Never use an open flame to detect gas leaks. Use a leak test solution for leak testing

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

2. Test appropriate sensors for accuracy

3. Ensure sensors are properly seated in wells with thermopaste installed

4. Check evaporator leaving water temperature low temperature cutout setpoint

5. Condenser high pressure switch check-out

6. Check adjustment and operation of the inlet guide vane actuator;

- Lubricate the gantries annually

1. Use ConocoPhillips Gantries MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi-Purpose (blue in color), or equivalent

- Lubricate the hinges annually

1. Use ConocoPhillips MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi- Purpose (blue in color), or equivalent;

- 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;
