2. Make sure the drain hose and copper tubing are
wrapped with the rubber insulation. Using the tape,
wrap the AC connection wire, copper tubing and drain
hose together.
MOUNTING (INDOOR UNIT)
The Indoor unit must be mounted before connecting the AC connection wire, drain hose and copper tubing. To mount,
follow the procedures below:
1. The tubing can be extended in 4 directions as shown
below. No cutting is necessary for left/rear and
right/rear tubing connections. If using left or right tub-
ing connections, remove the plastic area with a hack-
saw so pipes can go through.
CAUTION:
• Make sure the outdoor unit’s AC cord is not
connected to AC power when performing these procedures.
• Be sure to comply with local codes on running a wire
from the indoor to the outdoor unit.
• DO NOT LET THE AC CONNECTION WIRE
COME IN DIRECT CONTACT WITH THE TUBING
OR HOSE!
3. Shape the tubing so it can easily go through the hole
in the wall. Push the AC connection wire, copper tub-
ing and drain hose through the hole in the wall angling
downward. Situate the indoor unit on the wall bracket
by lifting the indoor unit slightly above the wall bracket
and then down so it is securely locked in place.

CAUTION:
• When using the tube reamer, hold the tube downward and make sure no copper scraps fall into the tubing.
2. Make a flare at the end of the copper tube with a flare
tool.
Make sure the inside surface and edges are smooth
and the sides are uniform length.
1. Cut the copper tube extension to the desired length
with a tube cutter. It is highly recommended that 1 foot
is added to the requested length. After cutting, debur-
ring may be necessary (see below diagram). Perform
this with a tube reamer.
