Step 7: Wrappping 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(This may not applicable
for some locations in US).
1.
Bundle the drain hose, refrigerant pipes, and
signal cable as shown below:
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.
