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 area

Select14 Series Air Curtain is developed to fit all
entrances. Recommended installation height up
to 14 ft. The air curtain is available without heat,
with electrical heating and with water heating.
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/rear of the unit and
blown downwards/outwards shielding the door
opening and minimizing 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 the outlet air is adjustable
and is normally angled outwards to achieve the
best protection against incoming air.
The efficiency of the air curtain depends on the
air temperature, the pressure differencial across
the doorway and any wind load.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.
Mounting
The air curtain range can be adapted for vertical
or horizontal installation. The units can also be
installed by recessing into suspended ceilings.
Horizontal 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 70.9 in. For
other minimum distances, see fig. 3.
For the protection of wider openings, several
units can be mounted next to each other using a
joining kit (fig. 9).
A design kit for a neat installation that conceals
cables, pipes and mountings is available for
both wall and ceiling installations, se accessories
pages.
