Trane CenTraVac™ Water-Cooled Chiller CVHF - 300-500 - 379 - 080S / 080L

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

Use a non-destructive tube test to inspect the condenser and evaporator tubes

Tube test performed on condenser?

Tube test performed on evaporator?

It may be desirable to perform tube tests on these components at more frequent intervals depending upon chiller application

This is especially true of critical process equipment

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

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
