Check to ensure that the ceiling slab is strong
-
enough. If not strong enough, the indoor unit may fall
down on you.
Do not install the indoor units, outdoor unit, remote
-
control switch and cable within approximately 3
meters of strong electromagnetic wave radiators such
as medical equipment.
Do not install the indoor units in a machinery shop or
-
kitchen where vapor from oil or mist flows to the
indoor units. The oil will deposit on the heat
exchanger, thereby reducing the indoor unit
performance, and may deform. In the worst case, the
oil damages the plastic parts of the indoor unit.
To avoid any corrosive action to the heat exchangers,
-
do not install the indoor units in an acid or alkaline
environment.
When lifting or moving the indoor unit, use
-
appropriate slings to avoid damage and be careful not
to damage the insulation material on units surface.
Consider the air distribution from the indoor unit to the
space of the room, and select a suitable location so that
uniform air temperature in the room can be obtained.

I
3 Fixing Screws
2. Mounting Bracket onto Wall
When the mounting bracket is directly attached to a
wood wall or a concrete wall, check to ensure that the
wall is strong enough to support a weight of 200kg.
3. Mounting the Unit between Pillars
Screws for wood market with
utilizing the upper hole.
It is not recommended that the mounting bracket be
installed on one pillar.
The location where the indoor unit is to be installed
should be so selected that an unbalanced weight
2~5 mm
distribution is avoided.
Diameter
of 65 mm
The mounting bracket should be installed so that the
(Hole for
piping)
side of drain piping connected is slightly (about 3mm)
lower than the other side, in order to avoid the incorrect
position of the drain discharge. (Drain piping connection
can be performed both right side and left side of the
unit.)
