6. Route the Sensor Leads
In this step you route the outdoor sensor leads to
the Control Box.
1.
Route the outdoor temperature sensor lead wires
down to the intermediate top and then under the
outdoor coil. See Figure 9, page 8. You may need to
lift the coil slightly to slide the sensor lead wires
under the coil.
2.
Route the outdoor temperature sensor leads down
into the compressor compartment through the one
(1") hole. See Figure 9. Using a wire tie from the
kit, tie the leads to the existing wiring at the point
where the leads go through the sheet metal
opening.
Ensure that the leads DO NOT lie
across the sharp sheet metal edges of the
openings.
3.
Continue to route the sensor leads through
the compressor compartment, through the
partition, and into the Blower compartment. From
the Blower compartment, continue to route the
leads into the Control Box.
Use wire ties to
secure the leads to the existing wires. This
ensures that any wiring is kept away from
the blower and sharp sheet metal.
4.
In the Control Box, route the sensor leads to the
Control Module. You make the connections later.
5.
Reinstall the outdoor fan assembly with the eight
(8) screws and screw caps you removed in the
Mount the Liquid Line Temperature Sensor
section.
6. To make your connections, continue with step

, page 9.
5. Mount the Outdoor Temperature Sensor
In this step you attach the outdoor sensor to the
outside of the outdoor coil. See Figure 9, page 8.
1.
On the outdoor fan grill, remove eight (8) plastic
screw caps covering the fan screws. Then, remove
the eight (8) screws that secure the outdoor fan grill
to the top of the unit. See Figure 8. Remove the fan
assembly and place it on top of the unit with the fan
blades facing up.
2.
Remove the back outdoor coil louvered panel to
access the outer surface of the outdoor coil:
a.) Remove the three (3) screws across the top of the
panel.
b.) Lift or slide the panel up enough to unhook it
from the slots in the unit.
4. Mount the Liquid Line Temperature Sensor
In this step you mount the liquid line sensor to the
liquid line. See Figure 7.
1.
Attach the liquid line temperature sensor to the
liquid line above the TXV as follows.
a.) Apply thermal compound (provided in kit) to an
area on the liquid line where you are mounting
the sensor. See Figure 7.
b.) Use the clamp (provided in kit) and attach the
sensor to the liquid line. See Figure 7.
c.) Wrap the sensor with insulating tape (provided
in kit).
2.
Route the sensor wires through the compressor
area, past the blower and into the Control Box. See
Figure 9, page 8.

3.
Insert the retainer into the outside surface of the
spine-fin coil about half way up the outside surface
of the coil. Attach the outdoor air sensor to the clip
on the outdoor air sensor retainer dart. See Figure
8 below and Figure 9, page 8.
