TCO1 Instructions
If the unit is installed in horizontal configuration, the
factory installed limit control TCO1 must be replaced
with the TCO1 for horizontal applications shipped in
the heater compartment.
Replace TCO1 following instructions below.
1. Remove the heat section access panel.
2. Remove TCO1 from shipping location - attached to
the gas manifold vertical leg - as shown below:

3. Replace and discard the existing TCO1 originally
installed at the factory for down flow operation with
the TCO1 from Step 2 for horizontal operation.
4. Reinstall the heat section access panel.

Condensate Drain Configuration
An evaporator condensate drain connection is
provided on each unit. Refer to
for the appropriate drain location.

e:: Use 1-inch PVC pipe to connect to the drain pan
outlet provided in the unit. This is a slip fit joint
(no threads). Do not use PVC glue to connect
condensate drain, thread sealing compound or
Teflon tape may be used.
A condensate trap must be installed at the unit due to
the drain connection being on the “negative pressure”
side of the fan.
A condensate drain line must be connected to the P-
Trap. Pitch the drain lines at least 0.5-inch for every 10
feet of horizontal run to assure proper condensate flow.
Do not allow the horizontal run to sag causing a
possible doubletrap condition which could result in
condensate backup due to “air lock”.
