1. Connect Y or Y/Y2 terminal as shown for proper cooling operation.

 

 

 

 

 

 

 

 

 

 

2. Proper polarity must be maintained for 115-v wiring.

 

 

 

 

 

3. Use W2 with 2-stage thermostat when zoning.

 

 

 

 

 

4. If any of the original wire, as supplied, must be replaced, use

 

 

 

 

 

 

same type or equivalent wire.

 

 

 

 

 

 

5. Some thermostats require a "C" terminal connection as shown.

* Permissible limits of voltage range at which unit will operate 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 load amps.

}Length shown is as measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop. ** Time---delay type is recommended.

!WARNING

ELECTRICAL SHOCK AND FIRE HAZARD

Failure to follow this warning could result in electrical shock, fire, or death.

The cabinet MUST have an uninterrupted or unbroken ground according to NEC ANSI/NFPA 70-2008 and Canadian Electrical Code CSA C22.1 or local codes to minimize personal injury if an electrical fault should occur. This may consist of electrical wire or conduit approved for electrical ground when installed in accordance with existing electrical codes. Do not use gas piping as an electrical ground.
