1. If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
2. Ensure the unit is unobstructed, allow proper
space on all sides according to the arrows
and distance measurements in the figures.
3. Do not place animals and plants in the path
of the warm air.
4. Take the air conditioner weight into account
and select a place where noise and vibration
are minimum.
5.
Select a place so that the warm air and sound
from the air conditioner does not disturb
neighbors.

Seaside Applications and Installation
Installation of Indoor, Outdoor Unit
1.
Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are
produced.
2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result
corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could
cause product malfunction or inefficient performance.
3.
If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind.
1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the outdoor unit on the opposite side of the sea wind direction.
2)
In case, to install the outdoor unit on the seaside, set up a windbreaker/barrier, to lessen the unit's exposure to sea air
3) Select a well-drained place.
• It should be strong enough (like concrete) to obstruct
the wind from the sea.
• The height and width should be more than 150% of
the outdoor unit.
• A minimum of 70cm (27 1/16 inches)
of space between outdoor unit and the windbreak
for easy air flow.
Sea wind Sea wind

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.

Installation of wired Remote Controller
1
Put the installation paper on the place and determine
the position and height of the fixing screws of the wired
remote controller.
• Refer to the printed side of the installation paper.
2
Plug the connecting cable into the indoor unit.
• The product is being shipped with the cable
connected only to the remote controller.
Fix the connecting cable with the cable rack.
3
Remove the installation paper before installing the
remote controller so that it can fit at the right place.
* Do not embed the remote controller into the wall.
(It may cause the breakdown of the
temperature sensor.)
* If you want to install a number of remote
controller at the same place in a vertical line,
install them at regular intervals of 20mm(1/32 inch).
(It may cause the breakdown of the temperature sensor.)
* Do not install the cable with a distance of 50m(164ft) or longer.
(This can cause communication error.)
* When installing the cable, check whether the connector between the remote controller and the
product is installed properly. The connector will not be connected when installed in opposite
sides.
❏ Supply the power after connecting wired remote controller.
When you need to change wired remote controller, switch off the main power and change it.
If the wired remote controller is changed before switching off the main power, the option function
of the indoor unit can't be used. (option function like "slo" fan speed selection)
