Recommended Maintenance
NOTICE
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.
RuptureGuard Maintenance
It is recommended that the RuptureGuard™ be visually
inspected.
The vent-line drip-leg must be periodically checked for
accumulation of water or refrigerant. Drain any
accumulation that may be present into an evacuated,
properly labeled vessel and dispose of in accordance with
local, state, and federal codes.
EarthWise Purge
Maintenance
To ensure efficient and reliable purge operation, perform all
inspections and procedures at the prescribed intervals.
Keep records of inspection results to establish proper
service intervals. Document changes that occur in purge
activity that could provide information about chiller
performance.
WARNING
Refrigerant under High Pressure!
Failure to follow instructions below could result in an
explosion which could result in death or serious
injury or equipment damage.
System contains refrigerant under high pressure.
Recover refrigerant to relieve pressure before
opening the system. See unit nameplate for
refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or refrigerant
additives.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.

Important:
•
Before servicing, disconnect all power
sources and allow at least 30 minutes for
capacitors to discharge.
•
All electrical enclosures—unit or remote—
are IP2X.
