Trane CenTraVac™ Water-Cooled Chiller CVHF - 350-910 - 957 - 080S / 080S

- Check the chiller’s evaporator and condenser pressures, oil tank pressure, differential oil pressure, and discharge oil pressure

- Compare the readings with the values provided in the general maintenance

- Check the oil level in the chiller oil sump using the two sight glasses provided in the oil sump head. When the unit is operating, the oil level should be visible in the lower sight glass

- Complete logs on a daily basis.

- 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;

- 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

1. Any voids or defects identified upon inspection must be repaired

2. If the water quality is known to be highly supportive of corrosion (i.e., sea water, etc.), inspect the coating system at one month

3. if the water quality is known to be relatively benign (i.e., normal treated and clean condenser water), inspect the coating system within three months

4. Only when initial inspections show no problems are present should subsequent maintenance intervals be increased;

- The replacement schedule for the optional zinc or magnesium anodes can vary greatly with the aggressiveness of the water that is in the system

- Some sites could require anode replacement every two to three months while other sites may require anode replacement every two to three years

1. Trane recommends inspection of anodes for wear sometime within the first several months of the anodes being placed into service

2. If the observed loss of anode material is small, then the interval between subsequent inspections can be lengthened

3. Replace the anode and/ or shorten the inspection interval if the anode has lost 50 percent or more of its original mass

4. If anode depletion occurs very quickly, consult a water treatment specialist to determine if the anode material selected is correct for the application

Failure to follow instructions could result in equipment damage

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

1. Perform Annual oil analysis (follow recommendations)

2. Clean and lubricate oil system as required

5. Run oil pump and check differential oil pressure;
