6.1 Preparing the installation site
Choose an installation location with sufficient space to transport the unit in and
out of the site.
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.
CAUTION
▪
Check if the installation location can support the unit's weight. Poor installation is
hazardous. It can also cause vibrations or unusual operating noise.
▪
Provide sufficient service space.
▪
Do NOT install the unit so that it is in contact with a ceiling or a wall, as this may
cause vibrations.
▪ 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.
▪ Provide sufficient space around the unit for servicing and air circulation.
▪ Avoid areas where flammable gas or product might leak.
▪ Install units, power cables and communication wiring at least 3 m away from
televisions or radios to prevent interference. Depending on the radio waves, a
distance of 3 m may not be sufficient.
NOTICE
Do NOT place objects below the indoor and/or outdoor unit that may get wet.
Otherwise condensation on the unit or refrigerant pipes, air filter dirt or drain
blockage may cause dripping, and objects under the unit may get dirty or damaged.
