 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.
Expansion valve kit:
BE SURE to use this kit if the unit is the model to mount the
expansion valve outside unit.
2.1.3. INSTALLATION
1. 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.
2. Mounting the Unit between Pillars
 Do not install the mounting bracket on one pillar.
 The location where the indoor unit is to be installed
should be so selected that an unbalanced weight
distribution is avoided.
 The mounting bracket should be installed so that the
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.)
