Assembly and operating instructions
Safety
• For all installations of electrically heated products
should a residual current circuit breaker 300 mA for
re protection be used.
• Keep the areas around the air intake and exhaust gril-
les free from possible obstructions!
• CAUTION! During operation the surfaces of the unit
can be hot!
• e unit must not be fully or partially covered with
clothing, or similar materials, as overheating can result
in a re risk! (E)
• e appliance can be used by children, aged from 8
years and above, and by persons (children included)
with reduced physical, sensory, or mental capabilities,

Application area
e AC22 air curtain unit is supplied without heating,
with electrical heating or hot water heating.
e AC22 is a compact air curtain, suitable for most small
entrances up to 2.2 metres in height. e air curtain has
an integrated control system and can be remotely control-
led.
Protection class for units with electrical heating: IP20.
Protection class for units without heating and units with
water heating: IP21.
Operation
Air is drawn in at the top of the unit and blown out
downwards so that it shields the door opening and mi-
nimizes heat loss. To achieve the optimum curtain eect
the unit must extend the full width of the door opening.
e grille for directing exhaust air is adjustable and is
normally angled outwards to achieve the best protection
against incoming cold air.
e eciency of the air curtain depends on the air tem-
perature, pressure dierences across the doorway and any
wind pressure.
NOTE! Negative pressure in the building considerably
reduces the eciency of the air curtain. e ventilation
should therefore be balanced.
Mounting
e air curtain unit is installed horizontally with the
supply air grille facing downwards as close to the door
as possible. Minimum distance from outlet to oor for
electrically heated units is 1800 mm. For other minimum
distances, see g. 4.
Mounting with wall brackets (g. 6)
1. Mount the brackets on the wall, see g.6A and
dimension drawing g.1. If the wall is uneven
the brackets must be compensated for this.
2. Hook on the unit at the lower edge of the brackets.
(Fig.6B-C)
3. Bend the top of the console over the unit
and slide the units screws along the rail into
the slots on the consoles, (Fig.6D). When the
bracket is bent once, it must be replaced if bent
back more than 45 °.
4. Lock the nuts against the brackets. (Fig.6E)
