General Information
The BC7*C-71 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
standard gas-fired furnace heat exchanger and at least
4" away from any drum-type or oil-fired furnace heat
exchanger. Closer spacing may damage the drain pan
and cause a leak.
Refer to the Product Specification bulletin (EHB) for
the proper use of these coils with specific furnaces, air
handlers and line sets.
These instructions are intended as a general guide and
do not supersede local or national codes in any way.
Authorities who have jurisdiction should be consulted
before installation.
IMPORTANT: Special procedures are required for
cleaning the aluminum coil in this unit. See page 10 in this
instruction for information.
