CONDENSATE DRAIN
A 3/4” condensate fi tting extends out of the side
of the unit. The drain trap, shipped in the electrical
compartment, must be installed to prevent water
from collecting inside the unit. Thread the elbow
provided with the unit into the drain connection
until hand tight. Install the trap into the fi tting and
seal the joint. Make sure it is level. Route the
condensate from the trap to a suitable drain. Any
connecting tubing or hose must have the outlet
below the trap level for proper drainage.
WARNING:
Turn off electrical power before servic-
ing controls. Severe electrical shock
may result unless power is turned off.
Unit must be installed in compliance
with the National Electrical Code (NEC)
and local codes.

1. Disconnect all electrical power to the unit
and remove the blower panel.
2. Locate the orange and red wires terminated
to the blower motor. The orange wire controls
cooling operation while the red wire controls
heating operation.
3. Verify the required speed from the airfl ow
data found in fi gure 7. Place appropriate wire
on the appropriate motor speed tap for the
required airfl ow point.
Note: If the same speed is required for both
heating and cooling, remove either the red
or orange wire from the blower motor. Next,
obtain the jumper wire from the homeowners
packet and connect it to the blower relays
at the coils on the blue wire and red wire
side.
