Wiring Work
Power supply wiring with accessory electric heat kit
13. Strip ½" of the insulation on the end of each power wire.
14. Connect the black supply wire to the high voltage connection lug on the accessory heat kit breaker.
15. Connect the white supply wire to the other high voltage connection lug on the accessory heat kit breaker.
16. Connect the green (ground) wire to the ground lug to the left of the accessory heat kit breakers and
tighten the ground lug screw. Make sure to leave extra slack in the ground wire to allow service to the unit
without disconnecting the ground wire. If the heat kit requires 2 circuits (dual circuit) , both circuit ground
wires must be connected to a ground lug (dual circuit kits have two individual ground lugs).
Ground Lug
17 Connect the six pin male plug on the electric heater assembly to the six pin female plug mounted at the
bottom of the control assembly door.
18. Remove the wiring diagram from the accessory heat kit. Remove the paper that covers the adhesive back
and place the electric heat wiring diagram over the wiring diagram located on the blower housing.
19. Route temperature sensor from the accessory electric heat kit to the lower section of the AHU cabinet.
Attach the sensor to the bottom of the suction pipe as shown below with included wire ties.
Suction Pipe
20. Wrap included insulation around the sensor and secure with included wire ties.
21. Remove the breaker opening cover plate on the AHU door and secure the doors to the unit.
NOTE: The electric heat kits are equipped with either one or two circuit breakers. These circuit breakers protect
the wiring inside of the AHU in the event of a short circuit. Additionally, these breakers provide a means of
disconnecting the power to the unit. The circuit breakers in the AHU's are not meant to protect the branch circuit
wiring between the furnace and the building's breaker panel. If sheathed cable is used, refer to NEC National
Electrical Code (NFPA 70) or the Canadian Electrical Code, Part I (CSA C22.1) and local codes for additional
requirements concerning supply circuit wiring. Electrical data can be found in Tables 2-5. IMPORTANT - All
installation on field wiring must be rated at 60ºC or higher. Please refer to the wiring diagrams on the furnace or
the tables this manual for more information. The 15kW and 20kW models may be connected to a single or dual
branch circuit. Refer to the NEC National Electrical Code (NFPA 70) or the Canadian Electrical Code, Part I (CSA
C22.1) and local codes for wiring material requirements.
