(8) High voltage wires matched to the load of the heaters,
fans, liquid line solenoid, and the controller.
(8) Spade Connectors matched to the gauge of high volt-
age wires
Wire labeling (numbers, colors, etc.)
Wire ties
18 gauge twisted shielded pair (if extending sensor wires)
Foam insulation if running wires outside the space.
Silicone (for sealing any box penetrations)
Accessories to Aid in Installation
The following parts are available separately:
10’ Wire Harness pn 20736, 25’ Wire Harness pn 20670, or 40’ Wire
Harness pn 20737
Further information on the Wire Harness can be found in literature
Q.1.21.
* When used with the KE2 Adaptive Control controller, the fuses must be sized to
match the application (i.e. Replace existing fuses with 30 Amp Time Delay fuses
for fans and compressor)
