Step 7: Wrap piping connections

In this step you will insulate the exposed line connections

coming from the indoor air handler with the supplied

sound deadening pads and insulation. Then wrap the line

set from the outdoor unit to the wall hole with the

supplied Non-Adhesive U.V. Tape.

Wrap the connectors at the indoor air handler tightly

with the supplied sound deadening pads.

Now, place the supplied insulation material over the

connectors and exposed refrigrant piping

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 Fig. 6.3 and the image below). DO NOT

wrap the end of the drain hose

Do not complete these steps until all of the refrigerant

piping connections have been checked for leaks.

If you would like the exterior piping on the

side of your home to have a sleeker, more

attractive look and add some extra protection

in the process, you can purchase a MRCOOL

LineGuard® Line Set Cover. This will encase

your refrigerant piping and lines, protecting

them from harsh weather conditions and sun

exposure, which will extend the life of your

system. These covers are available in various

sizes to ﬁt your particular application.

Wrapping the piping

upward will prevent

rain/moisture from

seeping into the

overlaps of the tape
