OPERATION AND MAINTENANCE
The engine and fan used in the
ACR Pro
air curtains are maintenance-free devices but regular check-ups are advised, especially mo-
tor 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 systematic cleaning 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 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 anti-freeze protection device. The heat exchanger may be damaged if the room
temperature goes below 0°C.
If the device is to operate in a room where the 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 hy-
draulic system/circulation. The liquid must be diluted with water accordingly to the manufacturer’s recommendation.
NOTICE !

input disconnected.
• Only suitably qualified staff well acquainted with the safety regulations concerning handling
with an electrical device must be employed when the device is being installed, started and op

therefore on both nozzles the shut-off valves should be installed. The order of connecting inlet/outlet pipes does not affect the operation
of the exchanger.
