STEP 8: WRAPPING THE CABLES

Before passing the piping, drain pipe, and the signal cable through the wall hole, you must bundle

them together to save space, protect them, and insulate them.

1. Bundle the drain pipe, refrigerant pipes, and signal cable as shown below:

Indoor Unit

Space behind unit

Refrigerant piping

Drain pipe

Signal wire

Insulation tape

NOTE

The drain pipe MUST be at the bottom of the bundle. Putting the drain pipe at the top of the

bundle can cause the drain pan to overﬂow, which can lead to ﬁre or water damage.

NOTE

DO NOT intertwine the signal cable with any of the other wires while bundling these items

together.

NOTE

When wrapping the bundle, keep the ends of the piping unwrapped. You need to access

them to test for leaks at the end of the installation process (refer to Electrical and Gas Leak

Checks section of this manual).

2. Using adhesive vinyl tape, attach the drain pipe to the underside of the refrigerant pipes.

3. Using insulation tape, wrap the signal wire, refrigerant pipes, and drain pipe tightly together.

Double-check that all items are bundled.

STEP 9: MOUNT INDOOR UNIT

If you installed new connective piping to the outdoor unit, do the following:

1. If you have already passed the refrigerant piping through the hole in the wall, proceed to #4.

2. Double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials

from entering the pipes.

3. Slowly pass the wrapped bundle of refrigerant pipes, drain pipe, and signal wire through the hole

in the wall.

STEP 7: PREPARE REFRIGERANT PIPING

1. If pre-existing refrigerant piping is already embedded in the wall, skip to Step 9. Then, begin the

outdoor unit installation. Refer to the Refrigerant Piping Connections section of the outdoor unit's

installation manual for detailed instructions.

2. If there is no pre-existing piping, connect the indoor unit’s refrigerant piping to the connective

piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connections

section of the outdoor unit's installation manual for detailed instructions.
