INSTALLATION INSTRUCTIONS
This manual must be left with the homeowner for future reference
Refrigerant Detection System Control (27A05) must be
ordered . RDS system requires 3 VA additional loading
on low voltage transformer.
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, personal
injury or loss of life. Installation and service must be
performed by a licensed professional HVAC installer or
equivalent, service agency, or the gas supplier.
The Clean Air Act of 1990 bans the intentional venting of

The NCUC*5S coil includes an externally equalized
factory-installed R-454B check/expansion valve and a
factory-installed R-454B refrigerant leak detection sensor.
The coil drain pan has a maximum service temperature
of 500°F. The drain pan must be at least 2" away from a
exchanger. Closer spacing may damage the drain pan
and cause a leak.
