SECTION I: GENERAL
The following list includes important facts and information
regarding the electric furnace and its inclusions.
1.

3.
Four-wire thermostat operation for heating and cooling
4.
A/C ready furnaces equipped with blower for A/C or
Heat Pump operation
5.
Holding Strap furnished with furnace
6.
This furnace is designed for downflow application
7.
This furnace must not be operated without furnace door
installed
NOTE: This furnace and its components listed on the

Blower Speed Tap Description
Tap 5 – High Speed – Cooling or Heat Pump Operation
Tap 4 – Med-High Speed – Cooling or Heat Pump Operation
Tap 3 – Medium Speed – Cooling or Heating Operation
Tap 2 – Med-Low Speed – Heating Operation
Tap 1 – Low Speed – Constant Circulation Operation Only.
Tap 1 air circulation is around 200 CFM. This is not enough
air flow for heating, cooling or heat pump operation. If Tap 1
is used for cooling the evaporator will freeze up. If Tap 1 is
used for heating with electric heat the limits will open in a
very short time frame.
DO NOT USE SPEED TAP 1 FOR HEATING OR
COOLING
