4 About the units and options
Select an installation site where the following conditions are fulfilled
and that meets your customer approval.
▪ The space around the unit is adequate for maintenance and
servicing. The space around the unit allows sufficient air
circulation and air distribution. See space required for installation.

If the switch box (c) is facing the wall, leave a service
distance of at least 600 mm and provide at least 1500 mm
space from air inlet (b) and air outlet (a) for air circulation.

▪ Make sure the area is well ventilated. Do NOT block any
ventilation openings.
▪ Make sure the installation site withstands the weight and vibration
of the unit.
▪ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings.
▪ 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.
▪ Drainage. Make sure condensation water can be evacuated
properly.
▪ In places with weak reception, keep distances of 3 m or more to
avoid electromagnetic disturbance of other equipment and use
conduit tubes for power and transmission lines.
▪ Fluorescent lights. When installing a wireless remote control
(user interface) in a room with fluorescent lights, mind the
following to avoid interference:
▪ Install the wireless remote control (user interface) as close as
possible to the indoor unit.
▪ Install the indoor unit as far as possible from the fluorescent
lights.
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit MUST be covered.
Do not install or operate the unit in rooms mentioned below.
▪ Places with mineral oil, or filled with oil vapour or spray, like in
kitchens (plastic parts may deteriorate).
▪ Where corrosive gas like sulphurous gas exists. Copper tubing
and brazed spots may corrode.
▪ Where the air contains high levels of salt, such as that near the
coast and where voltage fluctuates a lot (e.g. in factories). Also in
vehicles or vessels.
▪ 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.
▪ The unit can NOT be installed in a bathroom.
