a. Turn on the disconnect switches or breaker
switches to the "ON" position for the
condensing section and the air handler.
b. Test the unit in "COOLING" and "HEATING" to
ensure that full functionality of the unit has
been restored.
c. Run the split system in heating mode with the
heating elements engaged for at least 10
minutes to ensure the unit does not shut down
due to any temperature limiting device.
sTeP 14: Install the cover on the heater electrical
box and reinstall the air handler access panel(s)
with the screws that were set aside in Step 1(c).
Always contact your local distributor if there is
ever any doubt

Within this range of the units, the electric heater kit
will come with a separate heater electrical box to
be installed. The original air handler electrical box
will not be removed. Only some rewiring will be
required.
sTeP 1: DISCONNECT POWER:
Always disconnect electrical power to the air
handler and condensing section completely
from its electrical source prior to any servicing.
It is highly critical that all wires that are
disconnected within these steps are carefully
labeled so that reconnection is easy and accurate.
a. Turn the system to "OFF" from the unit's
thermostat
b. Turn the power to the condensing section and
air handler section off at the unit's disconnect
switch or breaker panel.

c. Remove the access panel from the front of the
air handler exposing the blower section. Place
the panel mounting screws aside in a safe place
as they will need to be reused when putting the
panels back on.
d. Disconnect the line voltage wires from the
blower motor power terminal block from the
service side and the ground wire from the
ground lug in the air handler electrical box.
sTeP 2: REMOVING THE AIR HANDLER
ELECTRICAL BOX:
a. Unplug the blower motor communication
harness at the motor control board and set
aside for reconnection later.
b. Disconnect the line voltage wiring from the
terminal block.
c. Disconnect ground wire from the ground lug.
d. The thermostat wires will terminate at a
common connection block on the motor control
board inside the electrical box of the air
handler. Unplug the thermostat terminal block
and set aside for reconnection later.
e. The low voltage wires from the condensing
section connect to the motor control board in
the air handler with ¼" insulated terminal
connections. Mark and disconnect these low
voltage wires from terminal connections; set
aside for reconnection later. The "C", "R", "O",
"Y1", & "Y2" should be labeled and
disconnected in this step.
f.
All wires leading into the air handler's electrical
box should now be loose at this point. If any
wires remain connected, go back through the
previous steps to ensure that all wires have
been properly labeled and disconnected before
proceeding.
g. Remove existing Electrical Box and set aside.
Retain the mounting screws as these will be
reused when reinstalling the air handler's
electrical box.
sTeP 3: Remove the heater collar cover plate(s) to
install the heater elements. (See Figure 1).
