For safety, before any cleaning, disconnect power supply using the controller.
It is forbidden to open the service door (risk of electrical discharge and being
trapped in fans).
Service and maintenance should be done only by introduced and qualified
workers.
Do not use water or steam for cleaning the internal parts and components of
the air curtain.
Air curtains don't need any kind of maintenance except from the cleaning of the casing and the inlet grille.
It is recommended to weekly clean the inlet grille. It's important to make sure that the air curtain is OFF,
otherwise the dust mixed with a wet cloth would create a kind of paste that will damage the fan rotor when it
sucks the air.
Annual cleaning of the discharge area (outlet).
The casing of the air curtain should be cleaned with a wet cloth and non-aggressive detergent. Do not use
caustic soap or acids.
The inlet grille prevents the settling of dust and strange objects in the internal elements. It is recommended to
check periodically that the inlet grille is free of any object that could interfere the air entrance (plastic bags,
papers, etc.).
In case of a micro drilled inlet grille (it has filter functions to prevent the entrance of dust to the internal
elements) use a vacuum cleaner with a soft brush in order to avoid any damages in the micro drilled grille.
We recommend cleaning the grille every week (depending on the amount of the incoming air dust).
In models with micro drilled grille is recommended to clean the inside of the unit with a vacuum at least once
every two years (*), best before the winter season, with qualified staff.
(*) These periods are indicative, depending on the ambient conditions of every installation.
In places with a high number of particles in suspension is desirable to increase the frequency of the internal
cleaning (including the city centers, near construction sites, etc.).
