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 120°F)

Cut a length of conduit to go from the controller to the evaporator 

  Measure the distance between the controller and evaporator to 

account for the extra length necessary to properly route conduit.

Determine the number of wires to go to the controller.

  Controller power (2 wires)

  Fan control (2 wires)

  Defrost (heater) control (2 wires)

  Liquid line solenoid (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 the number of wire is determined, cut the wires to length.

  The wire should be long enough to account for the necessary con-

nections in the controller and evaporator.

  Use the optional KE2 Wire Harness, or select different colored wires, 

(blue - fan, orange - heaters, yellow - solenoid, purple - alarm). This 

will simplify the installation and troubleshooting.  If only a single 

color is available, both ends of the wires should be labeled with a 

matching number. This will save time when wiring the evaporator.
