General Instructions
Read these instructions carefully prior to
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 should the product be used
in the manner intended and in accordance with
the instructions.
Application
Scand is a vertical air curtain specially designed
for revolving doors, with a curved design that
integrates neatly with the door. The air curtain
is available with electrical heating and with
water heating.
Protection class: IP20.
Operation
Air is drawn in at the side of the unit and blown
out against the entrance, so that it shields the
door opening and minimizes heat loss.
The grille for directing exhaust air is
adjustable and is normally angled towards the
revolving door 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
The air curtain is vertically mounted to the
left of the door seen from inside. Air curtains
for installation to the right can be specially
ordered. The unit has a curved design which
makes it an integrated part of the door.
Standard length is 2200 mm. Lengths up to
3 m can be ordered according to the product
key (extension without fans). Extension hoods,
for heights up to 4 m , are available as an
accessory.
The air curtain is installed on adjustable feet
which makes it possible to compensate for
any surface undulations. The feet are attached
to the floor with fasteners appropriate to the
surface and covered by a frame. Fasteners are
not included.
The air curtain must always be secured at the
top. The M8 press nut on the top of the unit is
used for this, see figure.
The product must be mounted in such a way
to allow future service and maintenance.
When mounting a product in stainless steel,
the protective plastic shall remain on the
product. The plastic is removed only when
mounting and installation are completed. Be
careful to not damage the surfaces.
Electrical installation
The installation, which should be preceded by
an isolator 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 air curtain has an integrated PC board
which is connected to the selected external
control system FC. FC must be ordered
separately. FC is supplied pre-programmed.
Communication- and sensor cables are
connected to the PC board.
Should more than one air curtain be
controlled by a single FC, an additional
communication cable FCBC per unit will be
required. See manual for FC.
Control is supplied by 230V~ to the PC board.
The PC board is placed in the top of the unit
and is accessed via cable glands on the top
or bottom of the unit. Pierce the gland with a
screwdriver before entering the cable. Cables to
the PC board should be routed through the unit
when the connection is made from the bottom.
Bundle the cables inside the unit to prevent
that they will be drawn into the fans or get in
contact with the heating elements.
For units with electrical heating, the power
supply for heating (400V3~) is connected to
the terminal block. The electrical connection
may be done from above or below, according
to ordering key. Connections made from
below the unit must be prepared in the floor
according to the drawing.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In the
distribution board, it is to be indicated that ”the
air curtains can be supplied from more than
one connection”.
