INDOOR UNIT INSTALLATION
12.2 INITIAL CHECK
?
N O T E
•
Install the indoor unit with a proper clearance around it for
operation, maintenance working space and safety.
•
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.
•
Avoid obstacles such as electric light, partition which may
hamper the air inlet or the air outlet flow.
•
Check to ensure that the ceiling has a sufficient strength to hang
the indoor unit.
•
Check whether the wall is vertical and flat.

If there is a cornice on the ceiling, measure the dimension from the front
or undersurface.

For the indoor unit with motion sensor, the detecting area for
the motion sensor is shown in the figure below.

•
Do not install the indoor unit in a machinery shop or kitchen
where vapor from oil or its mist flows to the indoor unit. The oil
will deposit on the heat exchanger, thereby reducing the indoor
unit performance and the plastic parts may deform, and in the
worst case, break due to splash oil at operation.
•
Avoid the installation place where the indoor unit may contact
high humidity.
•
The warmed air may stay at the high ceiling space during the
heating operation. Thus, the parallel installing of a circulator is
recommended.
•
The indoor unit can be installed up to 3.5 meters (for 1.5 to 3HP)
and 4.3 meters (for 4 to 6HP) from the floor level.
•
Avoid installing the air conditioning where the direct airflow
blows from the air outlet to the temperature detecting devices
such an alarm device or a control device. It may cause a failure
of an alarm device or a control device.

Multiple Combinations: the twin combination, the triple
combination and the quad combination for simultaneous
operation of indoor units are installed in a same room and
required to operate with equal conditions. In the case of
these combination indoor unit types, if each indoor unit is
partitioned by a wall, furniture or a curtain, etc, it may cause
an operation failure. In addition, in the case of rearranging
furniture or remodelling an interior after the installation, pay
Depth 7m
attention to effects for indoor units combination operation.
•
To avoid any corrosive action to the heat exchangers, do not
install the indoor unit in an acid or alkaline environment.

•
The temperature and humidity inside the ceiling have the
2.7m
potential to exceed 30 ºC/RH (Relative Humidity) 80%.
Thus, apply additional insulation materials to the indoor unit
external surface to avoid dew condensation.
