Trane CenTraVac™ Water-Cooled Chiller CVHF - 1070-1300 - 1062 - 210L / 210L

- 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;

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

1. Inspect for fouling and scaling in tubes

2. Check operation of evaporator water flow sensing device

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

- 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;

- 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;
