2. Selecting the installation location
2.1. Indoor unit
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Where it is not exposed to direct sunshine.
• At a distance 1 m or more away from your TV and radio (to prevent picture from
being distorted or noise from being generated).
• In a place as far away as possible from fluorescent and incandescent lights (so
the infrared remote control can operate the air conditioner normally).
• Where the air filter can be removed and replaced easily.
Warning:
Mount the indoor unit into a ceiling strong enough to withstand the weight of
the unit.
The indoor models should be installed the ceiling over than 2.5 m from floor.
Warning:
1. Install the unit in a space ith at least a minimum floor area defined in
the installation manual for the outdoor unit.
• Refer to the installation manual for the outdoor unit.
2. Install the unit only in a well-ventilated space.
3. Selecting an installation site & Accessories
• Select a site with sturdy fixed surface sufficiently durable against the weight of unit.
• Before installing unit, the routing to carry in unit to the installation site should be
determined.
• Select a site where the unit is not affected by entering air.
• Select a site where the flow of supply and return air is not blocked.
• Select a site where refrigerant piping can easily be led to the outside.
• Select a site which allows the supply air to be distributed fully in room.
• Select a site where the fan and drain pump noises will not be a problem.
• Do not install unit at a site with oil splashing or steam in much quantity.
• Do not install unit at a site where combustible gas may generate, flow in,
stagnate or leak.
• Do not install unit at a site where equipment generating high frequency waves (a
high frequency wave welder for example) is provided.
• Do not install unit at a site where fire detector is located at the supply air side. (Fire
detector may operate erroneously due to the heated air supplied during heating
operation.)
• When special chemical product may scatter around such as site chemical plants
and hospitals, full investigation is required before installing unit. (The plastic
components may be damaged depending on the chemical product applied.)
• If the unit is run for long hours when the air above the ceiling is at high
temperature/high humidity (due point above 26 °C), due condensation may
be produced in the indoor unit. When operating the units in this condition, add
insulation material (10-20 mm) to the entire surface of the indoor unit to avoid
due condensation.
3.1. Install the indoor unit on a ceiling strong enough
to sustain its weight
Secure enough access space to allow for the maintenance, inspection, and
replacement of the motor, fan, drain pump, heat exchanger, and electric box in one
of the following ways.
Select an installation site for the indoor unit so that its maintenance access space
will not be obstructed by beams or other objects.
(1) When a space of 300 mm or more is available below the unit between the unit
and the ceiling (Fig. 3-1-1)
• Create access door 1 and 2 (450 x 450 mm each) as shown in Fig. 3-1-2.
(Access door 2 is not required if enough space is available below the unit for a
maintenance worker to work in.)
(2) When a space of less than 300 mm is available below the unit between the unit
and the ceiling (At least 20 mm of space should be left below the unit as shown
in Fig. 3-1-3.)
• Create access door 1 diagonally below the electric box and access door 3
below the unit as shown in Fig. 3-1-4.
or
• Create access door 4 below the electric box and the unit as shown in Fig. 3-1-5.

2.2. Outdoor unit
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where it is not exposed to rain and direct sunshine.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase of operation
sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to fix the unit legs.
• Where it is at least 3 m away from the antenna of TV set or radio. (Otherwise,
images would be disturbed or noise would be generated.)
• Install the unit horizontally.
Caution:
Avoid the following places for installation where air conditioner trouble is
liable to occur.
• Where there is too much machine oil.
• Salty environment as seaside areas.
• Hot-spring areas.
• here sulfide gas exists.
• Other special atmospheric areas.
Warning:
The unit must be securely installed on a structure that can sustain its weight.
If the unit is mounted on an unstable structure, it may fall down causing
injuries.
Warning:
• This unit should be installed in rooms
specified in outdoor unit installation manual. Refer to outdoor unit
installation manual.
• Install the indoor unit at least 2.5 m above floor or ground level. For
appliances not accessible to the general public.
• Refrigerant pipes connection shall be accessible for maintenance purpose.
3.2. Securing installation and service space
• Select the optimum direction of supply airflow according to the configuration of
the room and the installation position.
• As the piping and wiring are connected at the bottom and side surfaces, and the
maintenance is made at the same surfaces, allow a proper space properly. For
the efficient suspension work and safety, provide a space as much as possible.
