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.
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.
