▪
Make sure the installation site withstands the weight and vibration of the unit.
▪
Make sure the area is well ventilated. Do NOT block any ventilation openings.
▪
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.
▪
Be sure that the air inlet 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.
▪
Choose a location where the operation noise or the hot/cold air discharged from
the unit will not disturb anyone and the location is selected according the
applicable legislation.
▪
Heat exchanger fins are sharp and injury is possible. Choose an installation
location where there is no risk for injury (especially in areas where children play).
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.
▪
Sound sensitive areas (e.g. near a bedroom), so that the operation noise will
cause no trouble.
Note:
If the sound is measured under actual installation conditions, the
measured value might be higher than the sound pressure level mentioned in
Sound spectrum in the data book due to environmental noise and sound
reflections.
INFORMATION
The sound pressure level is less than 70 dBA.
It is NOT recommended to install the unit in the following places because it may
shorten the life of the unit:
▪
Where the voltage fluctuates a lot
▪
In vehicles or vessels
▪
Where acidic or alkaline vapour is present
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.
