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.
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.
