Refrigerant Piping Connection

IMPORTANT

1. Wrap the connectors at the indoor air handler

tightly with the supplied sound deadening pads.

Refrigerant

piping

Drain hose

Non-Adhesive U.V.

Tape

Fig. 7.2

Wrapping the piping

upward will prevent

rain/moisture from

seeping into the

overlaps of the tape

2. Now, place the supplied insulation material over the

connectors and exposed refrigrant piping

3. Now, starting where the line set is not covered with

the factory plastic (close to the indoor air handler

connection, you will wrap the line set upward to the

wall hole, using the supplied Non-adhesive U.V. tape.

This will cover the insulated line set connections,

cables, and drain hose. The drain pipe will need to be

at the bottom of the bundle (Refer to Fig. 7.2).

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.

Step 6: Wrap Piping Connections

In this step you will wrap and insulate the exposed line

connections coming from the indoor air handler.
