Electric heat kit installation for air handlers:
AP, AE, AVC, AVV, MP, ME, MVC, AHR, AHE,
AHV, RFCX*E, and RFCX*P
Installation is the same for all air handler operating positions:
upflow, downflow, and horizontal right or horizontal left. Install
the electric heat kit before unit installation. See Figure 3 or Fig-
ure 4 for a depiction of the components.
1. Ensure that there is no electrical power going to the unit.
2. Remove the air handler blower access panel.
3. If installing the electric heat kit in an AP, AE, AVC, AVV, MP,
ME, MVC, RFCX*E2, or RFCX*P2 model, leave the ser-
vice disconnect bracket in position A as shown in Figure 4.
Or
If installing the electric heat kit in an AHR, AHE, AHV,
RFCX*E1, or RFCX*P1 model, move the service discon-
nect bracket to position B as shown in Figure 3.
4. If the electric heat kit does not have service disconnects,
go to Step 5.
Or
If the electric heat kit has service disconnects, complete
the following before Step 5:
a. Examine the electric heat kit and take note of the num-
ber of service disconnects it has. Remove the appro-
priate number of service disconnect knockouts from
the front access panel of the air handler unit.
b. Cut the blower access panel insulation behind the ser-
vice disconnect plate and remove to open the area for
the service disconnects to protrude through the front
access panel and provide clearance for the service
disconnects and single-point wiring entry kit.
c. Add replacement non-foil faced insulation for the
exposed front panel if needed. Add rubber gasket to
the inside of the door for sealing.
5. Remove and recycle the duct cover from the back panel of
the air handler control and wiring compartment.
