•  Circuit breakers installed in this unit provide short-

circuit protection of the internal wiring and serve as 

a disconnect. The circuit breakers DO NOT provide 

over-current protection of the supply wiring and may 

be sized larger than the branch circuit protection. 

Overcurrent protection of the supply wiring is 

provided by the breaker in the distribution panel 
and must be sized as shown in 

Table 6 (page 19)

.

It is recommended that the line voltage (240 VAC) to 

the furnace be supplied from a dedicated branch circuit 

containing the correct fuse or circuit breaker for the furnace. 

For minimum circuit ampacity and maximum over-current 
protection, see 

Table 6

. See unit wiring diagrams (

Figure 

23

Figure 24

Figure 25

, & 

Figure 26

) for wiring details. 

Electrical components are shown in 

Figure 19 (page 16)

Supply circuit requirements are listed below:

•  -010  model  is  factory-wired  for  single-branch  supply 

circuit only.

•  -012 models are factory-wired for single-branch supply 

circuit (single-circuit kit factory installed). Dual-branch 

circuit can be used by removing factory-installed 
single-circuit kit. See 

Figure 17

.

•  -015, -017, -020 and -023 models are factory-wired for 

dual-branch supply circuit. Single-branch circuit can 

be used by installing optional single-circuit kit.

Connecting Supply Service Wires

Power entrance for all models may be through the right 

side or through the bottom of the unit.

1. Remove right-hand control panel (when viewing in 

downflow position).

2. Locate power supply knockouts in side of unit and in 

bottom of unit. Remove appropriate plug(s) or knockout 

opening applicable to selected wire size(s).

 WARNING:

To avoid personal injury or property damage, 

make certain that the motor leads cannot 

come into contact with non-insulated metal 

components of the unit.

3. Install listed cable connector(s) in opening(s). If metal-

sheathed conduit is used for incoming power line(s), 

provide an approved metal clamp on conduit and secure 

it in entrance knockout.

4. Insert supply service wire(s) through cable connector(s) 

and connect wires to circuit breakers (

Figure 17

 & 

Figure 

18

). 

NOTE: To install single-circuit kit, perform step 5. 

If single-circuit kit installation is not needed, go to step 

6.

5. To install optional single-circuit kit:

a.  Loosen lugs at supply side of circuit breakers.

b.  Remove cover from single-circuit kit (if supplied).

c.  Insert metal buss bars of kit into lugs of circuit 

breaker.

d.  Tighten lugs securely (45 in.-lbs. recommended).

6. Connect service ground wire(s) to grounding lug(s) 

provided. One ground is required for each supply circuit 
used. See 

Figure 19 (page 16)

.

Grounding

 WARNING:

To minimize personal injury, the furnace cabinet 

must have an uninterrupted or unbroken electrical 

ground. The controls used in this furnace require 

an earth ground to operate properly. Acceptable 

methods include electrical wire or conduit 

approved for ground service. Do not use gas 

piping as an electrical ground!

Thermostat / Low Voltage Connections

•  The furnace is designed to be controlled by a 24 VAC 

thermostat. The thermostat’s wiring must comply with 

the current provisions of the NEC (ANSI/NFPA 70) 

and with applicable local codes having jurisdiction.

•  The  thermostat  should  be  mounted  about  5  feet 

above the floor on an inside wall. DO NOT install the 

thermostat on an outside wall or any other location 

where its operation may be adversely affected by 

radiant heat from fireplaces, sunlight, or lighting 

fixtures, and convective heat from warm air registers 

or electrical appliances. Refer to the thermostat 

manufacturer’s instruction sheet for detailed mounting 
information. See 

Figure 22 (page 18)

 for typical 

thermostat connections.

•  For  proper  indoor  blower  operation  and  temperature 

rise, the RE9X electric furnace requires that the system 

thermostat be configured NOT to call for the indoor 

blower to operate in the heating mode. Refer to your 

specific thermostat installation instructions for details 

on the heating mode indoor blower configuration.

•  The  RE9X  series  electric  furnaces  incorporate 

an integrated control. The thermostat’s 1st stage 

compressor signal, 

Y, must be connected to the 

YELLOW control wire at the furnace to enable the 

indoor blower off-delay in the cooling mode.
