Binding The Pipes And Cables; Hanging The Indoor Unit - Trane 18 Series Installer's Manual

Binding the Pipes and Cables

Note: The refrigeration pipes shall be insulated separately to prevent heat transfer between the
two pipes.
1. At the beginning of the indoor connections, bind the insulated refrigerant pipes, power cable,
and drain hose by evenly wrapping them with an appropriate pipe tape.
2. When the drain hose needs to be separated from the binding towards the discharge point,
separate the power cable and drain hose from this binding.
3. Wrap and secure the drain hose connection at its end.
4. Evenly wrap the separately insulated liquid and gas pipes until they are close to the outdoor
connection.
5. Near the outdoor unit connection, separately wrap these pipes.

Hanging the Indoor Unit

Note: It is recommended the indoor unit be mounted on a non-porous flat surface. Doing so will
reduce unfiltered air from entering the unit as well as reduce sweating behind the unit. Ensure the
insulation sections surrounding the refrigeration and condensate pipes are sealed and without
cracks or openings.
1. Insert the bound pipes and wires into the wall sleeve and pass through to the outside.
2. Hang the indoor unit on the wall-mounting frame.
3. Seal any and all openings and gaps with sealant.
4. Secure the wall pipe bundle with saddles.
5. Ensure the indoor unit is securely and tightly installed to the wall.
6. Do not bend the drain hose excessively to prevent blockage.
