Locating & Installing the Supply Damper(s)

 CAUTION:

If installing this air conditioning system in 

conjunction with a furnace, a damper must be 

installed in the furnace base assembly to prevent 

cold air from being discharged around the heat 

exchanger. Damage to the heat exchanger 

and asphyxiation may occur if a damper is not 

installed.
Check with the furnace manufacturer for damper 

requirements. Failure to install the required 

furnace damper may invalidate code agency 

listing and limited warranty on the furnace.

When locating the supply damper(s), carefully check floor joists 

and frame members that could interfere with the installation of the 

damper or flexible duct. Ideally, the damper should be located 

in the bottom of the main duct, forward of center of the home, 

at least three feet from the nearest register. See 

Figure 5

. The 

round supply opening in the slanted side of the damper should 

face the side of the home where the air conditioner is located.
1. Locate the center of the heat duct by cutting a small hole in 

the fiberboard below the duct at the desired location.

2. Cut a hole approximately 3/4” larger than the damper opening 

in the fiberboard.

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.

ELECTRICAL CONNECTIONS

 WARNING:

ELECTRICAL SHOCK, FIRE OR

EXPLOSION HAZARD

Failure to follow safety warnings exactly could 

result in serious injury, death 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 

Figure 10 (page 12)

 and 

Figure 11 (page 13)

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 power wiring 

hole (

Figure 7

). Connect L1 & L2 directly to the contactor.
