OPERATION AND MAINTENANCE

The engine and fan used in the GUARD PRO air curtains are maintenance-free devices but regular check-ups are advised,
especially motor and bearing (the 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 dirt/impurities. 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 the 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, 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 hydraulic system/circulation. The liquid must be diluted with water
accordingly to the manufacturer's recommendation.

Any repair and maintenance work must be conducted with the power off and the heat input disconnected.
