17.1 Preparing the installation site
17.1.1 Installation site requirements of the outdoor unit
▪ Provide sufficient space around the unit for servicing and air circulation.
▪ 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.
▪ 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.
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.
