Installing The Condensate Pipe; Wiring At The Indoor Unit - Trane 23 Series Installer's Manual

Installing the Condensate Pipe

Do not sharply twist or curve the condensate drain pipe. Ensure pipe ends are not submerged in
water. Drain pipe must provide adequate flow and slope downward to the outlet. Failure to do so
may result in leakage and overflow of the drain pan.
1. Connect the drain hose to the outlet pipe of the indoor unit (shown in Fig. A below).
2. Bind the joint with tape (shown in Fig. B below).
3. Wrap the pipe with insulating tape to prevent condensation (shown in Fig. C below).
Note: The drain pipe must be routed lower and sloped downward away from the indoor unit.

Wiring at the Indoor Unit

Disconnect all electrical power and discharge all energy storing devices such as capacitors to
the outdoor unit(s) prior to wiring the indoor unit(s) to avoid risk of death, injury, or damage to
equipment.
1. Open the front panel of the indoor unit, remove the screw on the wiring cover and remove the
cover (shown in Fig. D below).
2. Thread the power connection wire through the cable-cross hole at the back of the indoor unit
and pull it through to the front side (shown in Fig. E below).
