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
