General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
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
accordance with the instructions.
Application area
The ACCS air curtain is supplied with
electrical heating or hot water heating and is
intended to be mounted above or next to the
entrances and smaller doors up to 3 metres
in height.
Protection class: IP20.
Operation
Air is drawn in at the top/rear of the unit
and blown out downwards/outwards so that
it shields the door opening and minimizes
heat loss. To achieve the optimum air curtain
effect the unit must extend the full height/
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 temperature, 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
When mounting ACCS in stainless steel,
the protective plastic shall remain on the
product. Be careful to not damage the
surfaces.
Vertical mounting
The air curtain is mounted vertically as close
as possible to the door. For the best effect air
curtains should be placed on both sides of the
opening.
The air curtain is installed on adjustable
feet which makes it possible to compensate
for any surface undulations. The feet
Electrical installation
The installation, which should be preceded
by an omnipolar switch with a contact
separation of at least 3 mm, should only
be wired by a competent electrician and in
accordance with the latest edition of IEE
wiring regulations. The control system is pre-
installed in the air curtain with an integrated
control card.
SIRe is supplied pre-programmed with quick-
fit connections.
Modular cables are connected to the control
board. See manual for SIRe.
Unit with water heating
The electrical connection may be done from
above or below when mounted vertically, and
from left or right when mounted horizontally,
according to ordering key. Control (230V~)
should be connected to a terminal block.
Unit with electrical heating
The electrical connection may be done from
above or below when mounted vertically, and
from left or right when mounted horizontally,
according to ordering key. Control (230V~)
are attached to the floor with fasteners
appropriate to the surface and covered by a
frame.
The air curtain must always be secured at
the top.
Ensure that the front panel/service hatch is
accessible and can be fully opened.
See Fig.1, 2, 5, 6.
Horizontal mounting
The air curtain is installed horizontally with
the supply air grille facing downwards as
close to the door as possible.
The air curtain may be mounted on the wall
with brackets (accessory). The air curtain
can also be mounted hanging from the
ceiling.
Minimum distance from outlet to floor
for electrically heated units is 1800 mm.
Ensure that the front panel/service hatch is
accessible and can be fully opened.
