5. Monitor the system to determine the amount of
moisture remaining in the oil. It may be necessary to
replace the filter drier several times to achieve the
required dryness level. If system dryness is not
verified, the compressor will fail in the future.
Electrical Connections
WARNING
Electric Shock Hazard. Can cause
injury or death.
Line voltage is present at all
components on units with single-pole
contactors, even when unit is not in
operation!
Unit may have multiple power
supplies. Disconnect all remote
electric power supplies before
opening access panel.
Unit must be grounded in accordance
with national and local codes.
In the U.S.A., wiring must conform with current local codes
and the current National Electric Code (NEC). In Canada,
wiring must conform with current local codes and the current
Canadian Electrical Code (CEC).
Refer to the furnace or blower coil installation instructions
for additional wiring application diagrams and refer to unit
nameplate for minimum circuit ampacity and maximum
overcurrent protection size.
TRANSFORMER − 24VAC
Use the transformer provided with the furnace or coil blower
for low-voltage control power (24 − 40VAC minimum)
NOTE − The addition of accessories to the system could
exceed the 40VAC power requirement of the
factory-provided transformer. Measure the system’s
current and voltage after installation is complete to
determine transformer loading. If loading exceeds the
factory-provided transformer capacity, a larger
field-provided transformer will need to be installed in the
system.
