Sign off on the daily chiller maintenance

1. Since the evaporator is typically part of a closed circuit, it may not accumulate appreciable amounts of scale or sludge

2. Normally, cleaning every three years is sufficient

3. However, periodic inspection and cleaning is recommended on open evaporator systems, such as air washers;

- 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;

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.

Any voids or defects identified upon inspection?

If voids or defects are identified, they must be repaired.

Is the water quality known to be highly supportive of corrosion (i.e., sea water, etc.)?

If yes, inspect the coating system at one month.

Is the water quality known to be relatively benign (i.e., normal treated and clean condenser water)?

If yes, inspect the coating system within three months.

Did the initial inspections show no problems?

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