2. Determine if the hole is to be made at the left or right
hole location.

3. Using drill with hole-cutting attachment or equivalent, cut
a hole 65mm (2.56") in diameter. The hole should be
made at a slight downward slant to the outdoor side.
Measure the thickness from the inside to outside edges
and cut a PVC pipe at a slight angle 1/4" shorter than the
thickness of the wall and insert pipe in wall.

4. For sheetrock, wooden or similar wall, measure down
from the ceiling using a level or tape measure and
attach the wall bracket to the wall using 4 screws. If
you are not able to line up the holes with the beams,
use toggle bolts. Make sure the wall bracket is even
and flush against the wall.

CAUTION

• Before making hole, make sure there are no studs, pipes, electrical wiring or conduit directly behind the area to
be cut.

For Concrete, or similar type wall, make holes into the wall and insert concrete nails instead of screws.

2. Make sure the drain hose and copper tubing are
wrapped with the rubber insulation. Using the tape,
wrap the indoor/outdoor wire, copper tubing and drain
hose together.

MOUNTING THE INDOOR UNIT

The Indoor unit must be mounted before connecting the indoor/outdoor 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 tub­ing connections, remove the plastic area with a hack­saw so pipes can go through.

CAUTION:

• Make sure the Indoor 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 INDOOR/OUTDOOR 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 indoor/outdoor wire, copper tub­ing 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, debur­ring may be necessary (see below diagram). Perform
this with a tube reamer.

PREPARING THE COPPER TUBING (NOT INCLUDED)

A copper tubing extension (not included) may need to be cut. If this is the case, it will also have to be deburred and
flared as shown below:

1. Remove the flare nut stoppers from the inside unit.
Determine the location of the copper tubing and
where the bends will be. Gently bend the copper tub­ing, making sure to use big angles so no crimping will
occur. Try to do this on the first try as repeated bend­ing may break or crimp the tubing.

2. Remove the plastic stoppers from the tubing. Connect
the large and small copper tubing to the respective
extension and rotate the flare nut with your finger until
a smooth match is made. Make sure the copper
extension has foam rubber (insulation) on it.

CONNECTING COPPER TUBES

To connect the copper tubes, follow the procedures below:

NOTE:

When removing the flare nut stopper from the inside unit, confirm “Ping”, sounds because the mixed gas is charged in
the inside unit,

3. Once a smooth match is made, tighten the flare nut
using a wrench. Be very careful not to strip the
threads or flare nut. Repeat this process for the small
and large tubing. When tightening the flare nut, use
another wrench to securely hold the coupler from
twisting and possibly damaging the tubing.

4. Remove the flare nut stoppers from the outdoor unit’s
valves. Connect the larger copper tubing to the larger
valve on the outdoor unit. Connect the smaller copper
tubing to the smaller valve on the outdoor unit.

5. Perform a leak test on all copper tube connections. To
prevent heat loss and damage to walls from conden­sation, the copper tube connections coming from the
wall must be insulated. Do this by wrapping foam rub­ber or equivalent around the connection approximate­ly 8mm thick so no copper tubing is exposed.

NOTES:

• As with all wiring and hookups on this unit, make sure
the AC plug on the indoor unit is unplugged.

• Be very careful not to strip the threads or flare nut.

• When insulating the connections, use foam rubber or
equivalent.

1. Connect the drain hose extension to the drain hose
coming from the indoor unit by loosing the clamp on
the extension using a phillips screwdriver, attaching
the hoses together and then tightening the clamp.

2. Run the drain hose, slanted downward, outside. If the
drain pipe is exposed
indoors, make sure it is thor­oughly insulated so conden­sation does not ruin walls or
furniture or come in contact
with the AC connection or
extension. Also, do not
crease or form a trap in the
tubing.

CONNECTING THE DRAIN HOSE
