The heater kit is factory equipped with the supply and low volt-
age wires for the airhandler. The low voltage connection from
the heater kit is provided through a multi-pin plug which connects
to a mating plug in the airhandler. The high voltage connections
are to be made at the air handler contactor. These wires are to be
routed through the pipe nipples supplied with the heater kit as
shown in the following illustration:

Low Voltage Connections
The 24V-control voltage connects the airhandler to the room
thermostat and condenser. For systems using staged electric
heat, the thermostat is to have W1 and W2 functions. Low voltage
wiring is to be copper conductors, and be a minimum of 18AWG.
A provision on the cabinet side to accept the low voltage wiring is
provided. See the following drawings for typical low voltage
connections.

Heat Kit Installation
Inspect for Shipping Damage. The heat kit is an optional acces-
sory that is shipped separately from the air handler. Inspect the
heat kit for damage and report any damage to the carrier and/or
distributor. Do not install this accessory if it is determined that
the integrity or safety has been compromised by freight damage.
Check the Nameplate. From the heat kit nameplate check the
following:
·
The model number agrees with the approved models (see the
"Electric Heat" section of this manual).
·
The correct size (kW)
·
Electric characteristics, voltage and phase, agree with the
building electrical supply.
Attaching the Heat Kit The heat kit attaches directly to the top
panel (when viewed in the upflow position) of the airhandler. Do
not screw the heat kit into the duct flanges. See the following
drawing for details:
The wires from the heat kit are to be routed through the pipe
nipple into the air handler electrical compartment. See the "Elec-
trical Connection" section of this manual for wiring details.
