3. INSTALLATION WORK
Please obtain the approval of the customer when selecting the location of installation and
installing the main unit.
3.1. Selecting an installation location
Install the unit in a location that can withstand its weight, and where it will not topple or
fall.
Calculate the proper refrigerant concentration if you will be installing it in an enclosed
location.
Total amount of replenished refrigerant
in refrigerant facility (kg)
Capacity of smallest room where unit
is installed (m³)
If the results of the calculation exceed the concentration limit, increase the room surface
area or install a ventilation duct.
Please install the outdoor unit without slant. (within 3 degrees)
Install this unit in a location with good ventilation.
If the unit must be installed in an area within easy reach of the general public, install as
necessary a protective fence or the like to prevent their access.
Install the unit in an area that would not inconvenience your neighbors, as they could be
affected by the airfl ow coming out from the outlet, noise, or vibration.
If it must be installed in proximity to your neighbors, be sure to obtain their approval.
If the unit is installed in a cold region that is affected by snow accumulation, snow fall, or
freezing, take appropriate measures to protect it from those elements.
To ensure a stable operation, install inlet and outlet ducts.
Install the unit in an area that would not cause problems even if the drain water is
discharged from the unit. Otherwise, provide drainage that would not affect people or
objects.
Install the unit in an area that has no heat sources, vapors, or the risk of the leakage of
fl ammable gas in the vicinity.
Install the unit in an area that is away from the exhaust or vent ports that discharge
vapor, soot, dust, or debris.
Install the indoor unit, outdoor unit, power supply cable, transmission cable and remote
control cable at least 1 meter away from a television or radio.
The purpose of this is to prevent TV reception interference or radio noise. (Even if they
are installed more than 1 meter apart, you could still receive noise under some signal
conditions.)
Keep the length of the piping of the indoor and outdoor units within the allowable range.
For maintenance purposes, do not bury the piping.

3.2. Drain processing
Perform drain work in accordance with this Manual, and ensure that the drain water is
properly drained. If the drain work is not carried out correctly, water may drip down from
the unit, wetting the furniture.
When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe
and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may
freeze in extremely cold weather.
• As the drain water fl ows out of the outdoor unit during heating operation, install the
drain pipe and connect it to a commercial 16 mm hose.
• When installing the drain pipe, plug all the holes other than the drain pipe mounting
hole in the bottom of the outdoor unit with putty so there is no water leakage.

3.3. Installation dimensions
Provide suffi cient installation space, such as transportation route, maintenance space,
ventilation space, refrigerant piping space, and passageways.
Pay attention to the specifi cations of the installation space as shown in the fi gure. If
the unit is not installed according to specifi cations, it may cause short circuit or poor
performance. The unit may be prone to lapse into non-operation due to high pressure
protection.
When there is a wall in front of the unit, provide a space of 500 mm or more as mainte-
nance space.
When there is a wall at the right side of the unit, provide a space of 25 mm or more as
maintenance space.
An outdoor temperature of 35°C (DB) in air-conditioned operation is assumed for the
installation space in this item. If the outdoor temperature exceeds 35°C (DB) and the
outdoor unit is operating at a load exceeding its rated ability, provide a larger inlet
space.
If you are installing more outdoor units than indicated here, please ensure suffi cient
space or consult your distributing agent as it may affect the performance due to short
circuit and other problems.
Consider the transportation route, installation space, maintenance space, and access,
and install the unit in a location with suffi cient space for the refrigerant piping.
Observe the installation space specifi cations
that are shown in the fi gures.
Keep the same space at rear air intake.
Provide the same space for the air intake at the
rear of the outdoor unit.
If the installation is not performed according to
the specifi cations, it could cause a short circuit
and result in a lack of operating performance.
As a result, the outdoor unit might easily be
stopped by high-pressure protection.
Installation methods not shown in the following examples are not recommended. Perfor-
mance may drop signifi cantly.
