2.1 Safety summary
D A N G E R
• Install the outdoor unit with sufficient clearance around it for operation and maintenance as shown in the next
pages.
• Install the outdoor unit where good ventilation is available.
• Do not install the outdoor unit where exists a high level of oil mist, salty air or sulphurous atmosphere.
• Install the outdoor unit as far as practical (being at least 3 meters) from electromagnetic wave radiator, such
as medical equipment.
• Keep clearance between units of more than 50 mm, and avoid obstacles that could hamper air intake, when
installing more than one unit together.
• Install the outdoor unit in the shade or not exposed to direct sunshine or direct radiation from high temperature
heat source.
• Do not install the outdoor unit in a place where a seasonal wind directly blows into the outdoor fan.
• For cleaning, use non-inflammable and nontoxic cleaning liquid. Use of inflammable agent may cause
explosion or fire.
• Work with sufficient ventilation, for working in an enclosed space could cause oxygen deficiency. Toxic gas
may be produced when cleaning agent is heated to high temperature by, e.g., being exposed to fire.
• Cleaning liquid shall be collected after cleaning.
• Pay attention not to clamp cables when attaching the service cover to avoid electric shock or fire.
C A U T I O N
• Check the foundation to be flat, leveled and strongly enough.
• Install the unit in a restricted area not accessible by the general public.
• Aluminium fins have very sharp edges. Pay attention to the fins in order to avoid injury.
• 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
from strong electromagnetic wave radiators, such as medical equipment.
• Do not install the indoor units in a machinery shop or kitchen, where vapour 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.
• To avoid any corrosive action to the heat exchangers, do not install the indoor units in an acid or alkaline
environment.
• When lifting or moving the indoor unit, use appropriate slings to avoid damage and be careful not to damage
the insulation material on units surface.
• This appliance must be used only by adult and capable people, having received the technical information or
instructions to handle properly and safely this appliance.
• Turn OFF all power switches before maintenance is performed.
• Do not start the cleaning procedures before 5 minutes of the stop of the unit.
D A N G E R
• Avoid obstacles which may hamper the air intake or the air discharge flow.
• Children must be supervised to ensure that they do not play with the electrical appliances.
• Before obtaining access to terminals, all supply circuits bust be disconnected.
