2. PURPOSE OF THE DEVICE
The air curtain is intended to be used in regions with a moderate and cold climate, in spaces where temperature ranges from -10 to
+40°C, in conditions free from external factors such as pollens and hydrometeor (horizontal precipitation).
In winter, air curtains protect against heat loss in rooms by directing an airstream across the entrance way and preventing cold air
from entering the heated space.. In summer, the curtains may be used as cooling devices preventing the entry of hot air and
pollutants from outside.
The ACR air curtains are designed to protect against heat losses in buildings of medium and high capacity and with a required
mounting height is of 4 m such as:
• supermarkets, large retail space,
• car showrooms and service stations,
• sports and show halls,
• exhibition surfaces

ACR air curtains Operation and Maintenance Documentation
ACR 1000-1500-2000 E Air curtains with electric heater
• Lack of voltage on surface of electric coil
• Signicantly lower coil temperature in comparison to old type of electric heaters (e.g. heat-
ing wires, spirals)
• Large heat exchange surface (surface of contact of the heat exchanger with heated air)
• Fully automatic heat control depending on air ow
• Complete elimination of the risk of system overheating due to self regulating heating mod-
ules (heat capacity automatically reduces when air ow goes down)
• Low energy consumption
ACR E series (with electric heater) are based on a new type of PTC electric coils J It is a modern and safe solution, additional advan-
tages of PTC heaters

5. INSTALLATION
When deciding on the air curtain position you should take into account such factors as:
• Ease of access for servicing,
• Access to water and electricity supplies
It is recommended to install the air curtain in position above the entrance opening, on the wall or under the ceiling, on support pins
or horizontal mounting brackets. It is also possible to mount it vertically to a wall or other structure using vertical mounting brackets.
It’s important to make sure that the unit is properly levelled. In case of positioning in a di󰀨erent way than horizontal or vertical, during
installation, damage to the fan may occur and in consequence malfunction of the unit.
Inlets and outlets cannot be blocked by any objects. When installing the curtains, keep in mind that you will have free access to the
control panel. With larger door openings, it is possible to mount more curtains of the same type, one by one, to create an
uninterrupted air ow. The curtain is permanently mounted in either a horizontal or vertical position (on the left/right side of the
entrance).
Curtain connection should be done in a serviceable manner, manual shut-o󰀨 valves should be installed on both nozzles to enable
disconnection. In case of a solenoid valve (option - automatics), it must be connected at the water outlet of the device, otherwise it
may be damaged. When tightening the pipeline to the exchanger, the heater connection must be protected against torque (which
may cause leakage in the exchanger).
Horizontal installation under the ceiling using mounting pins
Installation under the ceiling is done by using 4 M8 pins. In order to hang the device on the pins, drill holes Ø 8-9mm in the EPP
housing directly in front of the existing holes in the steel inlet grille. The exact location is indicated by special tags on the EPP
housing. The pins should be screwed into the nippers at a depth of 10-14mm.

Wall installation by means of a horizontal brackets
The curtain can be mounted to the wall in a horizontal position using 2 mounting
brackets to the horizontal system. In the brackets there are Ø9mm holes for M8
screws. In the EPP housing, drill holes Ø 12-13mm in front of existing holes in the
steel intake grille. The exact location is indicated by the special tags on the EPP
housing and the gure below. Then insert the spacer sleeves into the holes and x
the brackets. Screw the remaining screws into the nuts under the steel intake grille
so that both grips are in one plane. Locknuts under the handles are used to secure
the screws from unscrewing.

It is also possible to install the unit vertically with the engine downwards and upwards. Two vertical mounts are used for this purpose. In
the brackets there are Ø9mm holes for M8 screws. In the EPP housing, drill holes Ø 12-13mm in front of existing holes in the steel in-
take grille. The exact location is indicated by special tags on the EPP housing and the gure below. Then insert the spacer sleeves into
the holes and x the brackets. Screw the remaining screws into the nuts under the steel intake grille so that both grips are in one plane.
Locknuts under the handles are used to secure the screws from unscrewing.

ACR air curtains Operation and Maintenance Documentation
It is important to note that the minimum distance between the unit and the oor for installation with engine at the bottom is not less than
100mm. This allows access to the electrical terminal strip and to the water exchanger vent.
The connection of the heating medium to the heat curtain, using G 1/2” threaded connections, should be made on the basis of a design
by an authorized designer. If the air curtain is connected to a district heating network without a mixing unit, a water lter is required.
In case of horizontal and vertical mounting with nozzles at the top, the exchanger is vented through the nozzles. If the device is mount-
ed vertically with nozzles at the bottom, to vent the exchanger, use a vent which is located on the exchanger collector on the engine
side.

10. 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 systematic cleaning of all dirts /impurities o󰀨. 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 n due to high possibility of damaging them. If the n 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 re 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.
