OPERATION AND MAINTENANCE
The engine and fan of the ACR air curtains are maintenance-free devices but regular check-ups are advised, especially motor and
bearing (fan’s rotor should rotate freely, free from any axial and radial throws/run-outs and undesired knocks/rattles.
The heat exchanger requires systematical cleaning of all dirts /impurities off. Before the start of the heating period, the heat exchanger
is advised to be cleaned with compressed air directed to the air outlets; there is no need for dismantling of the device.
Pay special attention when cleaning the exchanger’s fin due to high possibility of damaging them. If the fin is bent use a special tool. If
the device has not been used for a longer period of time, unplug it before the next use.
The heat exchanger is not equipped with any fire protection device. The heat exchanger may be damaged if the room temperature
goes below 0°C; anti-freeze liquid must be added to the water circulation/system. Anti-freeze liquid must be appropriate for the
material the exchanger is made of (copper) as well as other elements of the hydraulic system/circulation. The liquid must be diluted
with water accordingly to the manufacturer’s recommendation.
NOTICE !
• Any and all repair and maintenance works must be conducted with the power off and the heat
input disconnected.
