AC22
Assembly and operating instructions
Safety
• For all installations of electrically heated products
should a residual current circuit breaker 300 mA for
fire protection be used.
• Keep the areas around the air intake and exhaust gril-
les free from possible obstructions!
• CAUTION! The unit may have hot surfaces during
operation and when cooling down!
• The unit must not be fully or partially covered with
clothing, or similar materials, as overheating can result
in a fire risk! (E)
• The appliance can be used by children, aged from 8
years and above, and by persons (children included)
with reduced physical, sensory, or mental capabilities,
or lack of experience and knowledge, if they have been
given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards
involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be made
by children without supervision.
Children, of less than 3 years of age, should be kept
away unless continuously supervised.
Children, aged from 3 years and less than 8 years, shall
only switch on/off the appliance, provided that it has
been placed or installed in its intended normal opera-
ting position and they have been giving supervision or
instruction concerning use of the appliance in a safe
way and understand the hazards involved. Children,
aged from 3 years and less than 8 years, shall not plug

General instructions

Read these instructions carefully before installation and

The product may only be used as set out in the assembly
and operating instructions. The guarantee is only valid
if the product is used in the manner intended and in ac-
cordance with the instructions.

Application area

The AC22 air curtain unit is supplied without heating,
with electrical heating or hot water heating.
The AC22 is a compact air curtain, suitable for most small
entrances up to 2.2 metres in height. The 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 effect
the unit must extend the full width of the door opening.
The grille for directing exhaust air is adjustable and is
normally angled outwards to achieve the best protection
against incoming cold air.
The efficiency of the air curtain depends on the air tem-
perature, pressure differences across the doorway and any
wind pressure.
NOTE! Negative pressure in the building considerably reduces
the efficiency of the air curtain. The ventilation should therefore
be balanced.
Mounting
The 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 floor for
electrically heated units is 1800 mm. For other minimum
distances, see fig. 4.
Mounting with wall brackets (fig. 6)
1. Mount the brackets on the wall, see fig.6A and
dimension drawing fig.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)
