STEP 8 - Continued

STEP 9 - Inside

1. Pack the wall hole with the supplied Neoprene (or Spray

Foam), ﬁlling any space not taken up by the piping & lines, in

order to seal the hole.

2. To protect Quick Connect® connections and reduce

vibration, wrap them with the black sound deadening pads.

Then, install the white pipe insulation over the pads.

3. Now, starting at the outdoor condenser and working

your way up to the wall hole, you will wrap the exposed

line set, cables, and drain hose together tightly using the

supplied Non-adhesive U.V. tape. The drain pipe will need

to be at the bottom of the bundle. Refer to the diagram on

the previous page. DO NOT wrap the end of the drain

hose.

4. To further improve overall appearance and long-term

durability of the line set, it is recommended to install an

optional MRCOOL

LineGuard

(sold separately).
