ELECTRIC HEATER KIT 

This unit is not equipped with an electric heater kit.  A
factory approved, field installed UL listed heater package is
available from your equipment supplier. Heaters that are
not factory approved could cause damage which would not
be covered under the equipment warranty.  

Installation

Only EEC series electric heat assemblies may be installed into
the air handler. Consult installing contractor for the correct
electric heat assembly to be installed in each model of air
handler.

For ease of installation, it is recommended that the electric
heat kit be installed before the furnace plenum is installed.

1. Remove the upper access door from the air handler.

2. Remove and discard the field wiring compartment box by

removing the screws that attach it to the right side of the
air handler. 

3. The black and yellow high voltage transformer leads should

be connected to the terminal block or breaker of the heat kit.

4. From the electrical compartment, remove the cover plate

from the element housing.

housing. Install the screws provided through the assembly and
into the element housing.
