Installation and operating instructions
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
PAEC4000 is developed to fit all entrances.
Recommended installation height up to
4 meters/13.1 feet. 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.
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
1800 mm/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.
Mounting with wall brackets
1.
Remove the plastic covers on the wall brackets.
(Fig. 6A)
2.
Mount the brackets on the wall according to
measures in fig. 6B.
3. Fasten the hammer head screws on the unit in
the holes M8. (Fig. 5 and 6C)
4. Lock the nuts so that the hammer head screws
are at 20 mm/0.79 in height. Note the direction
of the screw heads. (Fig. 6C)
5.
Slide the unit on the consoles. (Fig. 6D)
6.
Lock the nuts against the bracket and put the
plastic covers on again. (Fig. 6E)
Horizontal mounting on the ceiling
Threaded rods, wire suspension kits and ceiling
brackets for ceiling mounting are available
as accessories, see fig. 7 and 8 and separate
manuals.
Horizontal recessed mounting in false ceilings
Outlet extension used for recessed installation
is available as an accessory, see fig. 10 and
separate manual.
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.
