1. Hook the indoor unit onto the upper portion of
the installation plate.(Engage the two hooks
of the rear top of the indoor unit with the
upper edge of the installation plate.) Ensure
that the hooks are properly seated on the
installation plate by moving it left and right.
Press the lower left and right sides of the unit
against the installation plate until the hooks
engage into their slots(clicking sound).
Connecting the pipings to the in
door unit and drain hose to drain
pipe
1. Align the center of the pipings and sufficiently
tighten the flare nut by hand.
2. Tighten the flare nut with a wrench.
3. When extending the drain hose at the indoor
unit, install the drain pipe.
Wrap the insulation material
around the connecting portion.
1. Overlap the connection pipe insulation
material and the indoor unit pipe insulation
material. Bind them together with vinyl tape
so that there is no gap.
2. Wrap the area which accommodates the rear
piping housing section with vinyl tape.

The wall you select should be strong and solid
enough to prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a
concrete wall, use anchor bolts.
•Mount the installation plate horizontally by
aligning the centerline using a level.
2. Measure the wall and mark the centerline. It
is also important to use caution concerning
the location of the installation plate-routing
of the wiring to power outlets is through the
walls typically. Drilling the hole through the
wall for piping connections must be done
safely.
■How to fix installation plate
•Drill the piping hole with a ø70mm hole core
drill. Drill the piping hole at either the right or
the left with the hole slightly slanted to the
outdoor side.

•Since the room temperature sensor is in the remote controller, the remote controller box should be installed
in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space
temperature.
Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average
temperature.
Do not install the remote controller where it can be affected by:
- Drafts, or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall behind the remote controller.
- This remote controller is equipped with a seven segment LED. display. For proper display of the remote
controller LED's, the remote controller should be installed properly as shown in Fig.1.
