Electrical Wiring
Electrical shock hazard.
Turn OFF electric power at fuse box or service panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage.
Failure to do so can result in property damage, personal injury and/or death.
All electrical work MUST conform with the requirements of local codes and ordinances and the National Electrical Code NFPA 70
current edition.
Electrical Heaters & Operating Controls
Timelow voltage transformer and the fan control are standard on a!l models and are prewired at the factory. To operate the blower coil, a heater accessory or a
Low Voltage Control Connections
The 24 volt power supply is provided by an internally wired low voltage transformer which is standard on all models. If power supply is 208 volt, the low voltage transformer must be rewired to the 208 volt tap. See the unit wiring label.
Field supplied low voltage wiring can enter the unit on the top left hand corner or the left hand side panel. When using the left hand
side panel entrance, the low voltage wiring must be fed through the entrance hole in the bottom of the control box.
Install the strain relief bushing (supplied with unit) in the selected hole and a hole plug (supplied with unit) in the unused hole.
Connect the field wiring at the screw terminals of the control board. Refer to Figure 9.
Keep the low voltage wiring as short as possible inside the control box.
Complete connections between indoor blower, outdoor section, indoor thermostat and electronic outdoor thermostat (accessory) according to instruction provided with the Condenser Installation Instructions or those provided with the accessory and refer to Fig- ure 10.
Install No Heat Kit
If electric heat is not used, install accessory No Heat Kit.
1..Locate adapter and filler plates, with screws inside pack- age unless they were preinstalled at the factory.
2..If necessary, attach adapter plate and filler plate to bracket as required to match cabinet, Refer to Figure 9.
3..Secure the no heat accessory with four screws.
4..Connect the plug from No Heat Kit wiring into the recep- tacle on the control board on the side of the cabinet.
Electric Furnace I
The power supply wiring to the unit MUST be provided with over- current protection. Governing codes may require this to be fuses ONLY or circuit breakers.
For blower cabinets without heaters, a 15 amp circuit may be used.
Line Voltage Connections
Line voltage wiring may be brought into the unit through the top
Grounding
Use a copper conductor (#14AWG) from the unit to a grounded connection in the electric service panel or a properly driven and electrically grounded ground rod.
Line Voltage Connection
1.A disconnect switch MUST be located within sight of the unit.
2.Provide line voltage power supply
3.Connect line voltage L1 and L2 to the lugs on the No Heat Kit, Figure 9.
