outdoor units. The handling or adjustment of these devices may
result in serious accident.

radiation from electromagnetic waves, such as medical equip-
ment.

•
work must be carried out by qualified service personnel with

N O T E
•
The air in the room should be renewed and the room ventilated
every 3 or 4 hours.
•
The system fitter and specialist shall provide anti-leak safety in
accordance with local regulations.
It is assumed that the air conditioning system will be installed
and maintained by responsible personnel trained for the
purpose. If this is not the case, the customer should include all
the safety, caution and operating signs in the native language of
the personnel responsible.
Do not install the unit in the following places, as this may lead to
a fire, deformities, rusting or faults:
•
Places where oil is present (including oil for machinery).
•
Places with a high concentration of sulphurous gas, such as
spas.
•
Places where flammable gases may be generated or
circulate.
•
Places with a saline, acidic or alkaline atmosphere.
Do not install the unit in places where silicon gas is present. Any
silicon gas deposited on the surface of the heat exchanger will
repel water. As a result, the condensate water will splash out
of the collection tray and into the electrical box. Water leaks or
electrical faults may eventually be caused.
Do not install the unit in a place where the current of expelled
air directly affects animals or plants as they could be adversely
affected.
