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.

condensate Drainage

A 3/4” condensate fitting extends out of the side of the 
unit as shown in 

Figure 4

. 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.
