Preparing the installation site
5.2.1
Installation site requirements of the
outdoor unit
INFORMATION
Also read the following requirements:
▪ General installation site requirements. See the
"General safety precautions" chapter.
▪ Service space requirements. See the "Technical data"
chapter.
▪ Refrigerant
piping
requirements
(length,
height
difference). See further in this "Preparation" chapter.
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit's weight and
vibration.
▪ Make sure the unit is level.
▪ Select a place where rain can be avoided as much as possible.
▪ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
▪ Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location is
selected according the applicable legislation.
▪ During installation, avoid the possibility that anybody can climb on
the unit or place objects on the unit.
▪ All piping lengths and distances have been taken into
consideration (see
"5.3.3 About the piping length" on page 13
).
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where there is a risk of fire due to the leakage of
flammable gases (example: thinner or gasoline), carbon fibre,
ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
NOTICE
This is a class A product. In a domestic environment this
product may cause radio interference in which case the
user may be required to take adequate measures.
CAUTION
Appliance NOT accessible to the general public, install it in
a secured area, protected from easy access.
This unit is suitable for installation in a commercial and
light industrial environment.
▪ When installing, take strong winds, typhoons or earthquakes into
account, improper installation may result in the unit turning over.
▪ Be sure that the air inlet and outlet of the unit is not positioned
towards the main wind direction. Frontal wind will disturb the
operation of the unit. If necessary, use a screen to block the wind.
▪ Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in
the construction.
▪ In heavy snowfall areas, select an installation site where snow will
not affect the operation of the unit.
Seaside installation.
Make sure the outdoor unit is NOT directly
exposed to sea winds. This is to prevent corrosion caused by high
levels of salt in the air, which might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example:
Behind the building.

If the outdoor unit is exposed to direct sea winds, install a
windbreaker.
▪ Height of windbreaker≥1.5×height of outdoor unit
▪ Mind the service space requirements when installing the
windbreaker.

NOTICE
The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.
It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc.
