ELECTRICAL CONNECTIONS

 WARNING:

ELECTRICAL SHOCK, FIRE OR EXPLOSION 
HAZARD

Failure to follow safety warnings exactly could 
result in serious injury or property damage.
Improper servicing could result in dangerous 
operation, serious injury, death or property 
damage.

•  Before  servicing,  disconnect  all  electrical 

power to the indoor blower.

•  When servicing controls, label all wires prior 

to disconnecting. Reconnect wires correctly.

•  Verify proper operation after servicing.

•  All electrical connections must be in compliance with 

all applicable local codes and ordinances, and with 
the current revision of the National Electric Code  
(ANSI/NFPA 70).

•  For Canadian installations the electrical connections 

and grounding shall comply with the current Canadian 
Electrical Code (CSA C22.1 and/or local codes).

Pre-Electrical Checklist

  Verify that the voltage, frequency, and phase of the 

supply source match the specifications on the unit 
rating plate.

  Verify that the service provided by the utility is sufficient 

to handle the additional load imposed by this equipment. 
Refer to the unit wiring label for proper high and low 
voltage wiring.

  Verify factory wiring is in accordance with the unit wiring 

diagram (Figures 10 - 12, pages 13 - 15). Inspect for 
loose connections.

Line Voltage

•  A wiring diagram is located on the inside cover of the 

electrical box of the unit. The installer should become 
familiar with the wiring diagram before making any 
electrical connections to the unit.

• 

An electrical disconnect must be located within 
sight of and readily accessible to the unit. 

This 

switch shall be capable of electrically de-energizing 
the unit.

•  Line  voltage  to  the  unit  should  be  supplied  from  a 

dedicated branch circuit containing the correct fuse 
or circuit breaker for the unit. Incoming field wiring 
and minimum size of electrical conductors and circuit 
protection must be in compliance with information listed 
on the unit data label. Any other wiring methods must 
be acceptable to authority having jurisdiction.

•  Provide power supply for the unit in accordance with the 

unit wiring diagram, and the unit rating plate. Connect 
the line-voltage leads to the terminals on the contactor 
inside the control compartment. Extend leads through

3. Cut a 9-1/8” x 13-1/8” hole in the duct and bend over 

all tabs flat on the inside of the heat duct.

4. Insert the damper into the duct and bend over all tabs 

flat on the inside of the heat duct.

5. Seal the opening between the fiberboard and damper 

or flexible duct.

Condensate Drainage

A 3/4” condensate fitting extends out of the side of the 
unit (Figure 6). The drain trap, shipped in the electrical 
compartment, must be installed to prevent water from 
collecting inside the unit.
1. Thread the elbow provided with the unit into the drain 

connection until hand tight.

2. Connect the condensate tubing onto the fitting, forming 

a trap near the drain connection.

3. Route the condensate tube from the trap to a suitable 

drain. 

NOTE:

 For proper drainage,

 

make sure the trap is 

level to the ground and tubing outlet is below trap level.
