3. INSTALLATION WORK
Correct initial installation location is important because it is diffi cult to move unit after it is
installed.
48 type
Installation requirements will be explained with illustrations using the 72 type as
reference.
3.1. Selecting an installation location
Decide the mounting position together with the customer as follows.
Select installation locations that can properly support the weight of the indoor unit.
Install the units securely so that they do not topple or fall.
Do not install the indoor unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts,
causing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam,
such as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit
to leak water.
• Area that generates substances that adversely affect the equipment, such as sulfuric
gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to
corrode, which can cause refrigerant leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fi re.
• Area where animals may urinate on the unit or ammonia may be generated.
Do not use the unit for special purposes, such as storing food, raising animals,
growing plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near a source of heat, steam, or fl ammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, power supply cable, transmission cable, and remote controller
cable at least 40 in (1 m) away from a television or radio receivers. The purpose of this
is to prevent TV reception interference or radio noise. (Even if they are installed more
than 40 in (1 m) apart, you could still receive noise under some signal conditions.)
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Take precautions to prevent the unit from falling.
(1) Install the indoor unit on a place having a suffi cient strength so that it withstands
against the weight of the indoor unit.
(2) The inlet and outlet ports should not be obstructed; the air should be able to blow all
over the room.
(3) Leave the space required to service the air conditioner.
(4) Install the unit where connection to the outdoor unit (or RB unit) is easy.
(5) Install the unit where the connection pipe can be easily installed.

(6) Install the unit where the drain pipe can be easily installed.
(7) Install the unit where noise and vibrations are not amplifi ed.
(8) Take servicing, etc., into consideration and leave the spaces. Also install the unit
where the fi lter can be removed.
(9) Do not install the unit where it will be exposed to direct sunlight.
3.2. Installation dimension

3.2.3. (For maintenance)
(1) Maintenance work of the control box is possible with the Service access of the
measurement shown in the fi gure.
(2) If maintenance work is to be done from the bottom side, the Service access needs to
be larger than the outside dimension of the indoor unit.
(3) If maintenance work is to be done from the top, keep the space of the more than 18 in
(450 mm) between the indoor unit and ceiling.

3.3. Installing the unit
Install the air conditioner in a location which can withstand a load of at least 5 times
the weight of the main unit and which will not amplify sound or vibration. If the
installation location is not strong enough, the indoor unit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk that the unit will come loose.
Please take care.
Carrying in and installation of the unit should be performed by a suffi cient number of
people and with suffi cient equipment that is adequate for the weight of the unit. Per-
forming such work by an insuffi cient number of people or with inadequate equipment
could result in dropping of the unit or personal injury.
Confi rm the directions of the air intake and outlet before installing the unit.
The unit takes in air from the evaporator side, and expels it from the fan side.
