Step 7: Wrappiping and cables
Before passing the piping, drain hose, and the
signal cable through the wall hole, you must
bundle them together to save space, protect
them, and insulate them.
Bundle the drain hose, refrigerant pipes, and
1.
signal cable as shown below:
Indoor Unit
Signal wire
DRAIN HOSE MUST BE ON BOTTOM
Make sure that the drain hose is at the bottom
of the bundle. Putting the drain hose at the
top of the bundle can cause the drain pan
to overflow, which can lead to fire or water
damage.
DO NOT INTERTWINE SIGNAL CABLE WITH
OTHER WIRES
While bundling these items together, do not
intertwine or cross the signal cable with any
other wiring.
2. Using adhesive vinyl tape, attach the drain
hose to the underside of the refrigerant pipes.
Using insulation tape, wrap the signal wire,
3.
refrigerant pipes, and drain hose tightly
together. Double-check that all items are
bundled.
DO NOT WRAP ENDS OF PIPING
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 Checks
and Leak Checks section of this manual).
