Unit Installation; Initial Check - Hitachi RCI-1.0FSN3E series Installations- Und Betriebshandbuch

3 Units installation
C A U T I O N :
• Do not install the indoor units in a flammable environment to avoid
a fire or an explosion.
• Check to ensure that the ceiling slab is strong enough. If not
strong enough, the indoor unit may fall down on you.
• Do not install the indoor units, outdoor unit, remote control switch
and cable within approximately 3 meters of strong electromag-
netic wave radiators such as medical equipment.
• Do not install the indoor units in a machinery shop or kitchen where
vapor from oil or mist flows to the indoor units. The oil will deposit
on the heat exchanger, thereby reducing the indoor unit performance,
and may deform. In the worst case, the oil damages the plastic parts
of the indoor unit.
