General
CH35
all-aluminum
coil
horizontal evaporator coils are
designed for use with air conditioners and heat pumps.
Each coil is equipped with a compression fitting that
provides convenient field installation of a properly sized,
separately ordered expansion valve.
The coil drain pan is high quality engineering polymer with
a maximum service temperature of 500°F. However,
adequate space must be provided between the drain pan
and furnace heat exchanger. At least 2" space is required
for heat exchanger and 4" for drum-type or oil-fired furnace
heat exchanger. Closer spacing may damage the drain
pan and cause leaking.
Refer to the CH35 Product Specification bulletin (EHB) for
proper use of these coils with specific furnaces, air
conditioners, heat pumps and line sets.
These instructions are intended as a general guide and do
not supersede local or national codes in any way. Consult
authorities who have jurisdiction before installation.
IMPORTANT:
Special procedures are required for
cleaning the aluminum coil in this unit. See page 8 in this
instruction for information.
