ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Blower door switch opens 115--v power to control. No
component operation can occur. Do not bypass or close
switch with blower door removed.
!
WARNING
See Fig. 33 for field wiring diagram showing typical field 115-- v
wiring. Check all factory and field electrical connections for
tightness.
Field--supplied wiring shall conform with the limitations of 63_F
(33_C) rise.

* Permissible limits of the voltage range at which the unit operates satisfactorily.
# Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other potential operating components’ (EAC, humidifier,
etc.) full l oad amps.
{Time---delay type is recommended.
}Length shown is as measured one way along wire path between furnace and service panel for maximum 2 percent voltage drop.
