Trane CenTraVac™ Water-Cooled Chiller CVHF - 190-320 - 231 - 032L / 032L

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

Test appropriate sensors for accuracy

Ensure sensors are properly seated in wells with thermopaste installed

Check evaporator leaving water temperature low temperature cutout setpoint

Condenser high pressure switch check-out

Check adjustment and operation of the inlet guide vane actuator

Sign off on the control circuits inspection

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

Is the purge operated excessively?

If yes, repeat the second step more often.

Apply oil to any exposed metal parts to prevent rust

Warning: Equipment Damage! Failure to follow instructions could result in equipment damage

Do NOT use Teflon-based tape or paste on anode; a small amount of liquid sealant (Loctite® 242 or equivalent) may be applied to prevent leakage when installing an anode, but do not apply so much sealant that it prevents the necessary electrical connection between the anode and the waterbox

As needed after draining the waterbox, use a 2-1/2 in. (63.5 mm) wrench to remove/install Trane-supplied waterbox anodes

Inspection of anodes for wear within the first several months of the anodes being placed into service

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

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

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

Sign off on the anode replacement

Contact a qualified service organization to determine when to conduct a complete examination of the unit to discern the condition of the compressor and internal components

Check for evaporator water tube leaks

Check for condenser water tube leaks

Sign off on the yearly chiller maintenance

- 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;
