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
. 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.
