1.
If Heat Kit has circuit breakers - remove circuit breaker
knockouts from front of air handler unit. For kits with circuit
breakers, cut blower access panel insulation along foil
perforations behind the circuit breaker plate and remove to
open the area for the circuit breakers to protrude through
the front access panel and to provide clearance for circuit
breakers and single point wiring entry kit. Replacement
non-foil faced insulation for the exposed front panel may
then need to be added. Add rubber gasket to inside of
door.
