Determining Location
The controller is designed to be as versatile as possible. The loca-
tion should be discussed with the end users to determine if they have
a preference. It is designed so it can be installed inside or outside the
controlled space.
The controller can also be located at the condenser, but should not
be installed outdoors without an enclosure to protect it from sun-
light and moisture (must be within operating range -40°F to 140°F)
Evaporator
?
Cut a length of conduit to go from the controller to the evaporator
Measure the distance between the controller and evaporator to ac-
count for the extra length necessary to properly route conduit.
The wire whip has the following wires that go to the controller:
Controller power (3 wires)
Fan control (2 wires)
Defrost (heater) control (2 wires)
Liquid line solenoid (2 wires)
If the Aux Relay is used, the installer will need to supply an ad-
ditional pair of wires to the controller
Aux relay (2 wires)
Note: Install in accordance with local wiring codes. KE2 Therm
does not accept responsibility for incorrect or unsafe wiring.

Cut wires to length
Once wire locations are determined, cut the wires to length.
The wire should be long enough to account for the necessary con-
nections in the controller and evaporator.
Using the wire harness with different colored wires, (blue - fan,
orange - heaters, yellow - solenoid) will simplify the installation and
troubleshooting.

Determine the current draw of the unit.
Using the nameplate to determine the Amp rating of the unit. This
information should be used to select the proper sized wire. It should
also be used to verify the unit does not exceed the relay rating on the
KE2 Controlled Environment controller.
