RuptureGuard M aintenance

It is recom m ended that the RuptureGuard be visually
inspected and the relief valve pressure tested annually.
The test can be perform ed w ith the valve in place and the
refrigerant in the chiller.
The vent line drip leg m ust be periodically checked for
accum ulation of water or refrigerant. Drain any
accum ulation that m ay be present into an evacuated,
properly labeled vessel and dispose of in accordance w ith
local, state and federal codes.

EarthWise Purge M aintenance

M aintenance requirem ents for an EarthWise purge system
w ith Tracer AdaptiView control are described in this
section. 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. Docum ent changes that occur in
purge activity that could provide inform ation about chiller
perform ance.
WARNING
Contain Refrigerant!
Failure to follow proper procedures or the use of non-
approved refrigerants, refrigerant substitutes, or
refrigerant additives could result in death or serious
injury or equipment damage. System contains oil and
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.
N ot e: Graphic labels (show n above) are used for CE
application only.
Im port ant :
• Before servicing, disconnect all pow er sources and
allow at least 30 m inutes for capacitors to discharge.
• All electrical enclosures—unit or rem ote—are IP2X.
CAUTION
Hot Surfaces!
Failure to follow instructions below could result in
minor to severe burns. Surface temperatures may
exceed 148.9° C (300° F) on condensing unit and carbon
tank. Wear protective gear and allow surfaces to cool
before servicing these parts or any part located in their
vicinity.
