Assembly and operating instructions
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 PA2500C air curtain unit is supplied
without heating, with electrical heating or
hot water heating. PA2500C is intended for
installation heights up to 2.5 metres. The air
curtain has an integrated control system and
can be remotely controlled. 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 of the unit and
blown out downwards so that it shields the
door opening and minimizes heat loss. To
achieve the optimum curtain effect the
unit must extend the full 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
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. For other minimum
distances, see fig. 4.
Mounting with wall brackets (fig. 6)
1. Mount the brackets on the wall, see fig.6A
and dimension drawing fig.1. If the wall is
uneven the brackets must be compensated
for this.
2. Hook on the unit at the lower edge of the
brackets. (Fig.6B-C)
3. Bend the top of the console over the the
unit and slide the units screws along the
rail into the slots on the consoles. (Fig.6D)
When the bracket is bent once, it must be
replaced if bent back more than 45 °.
4. Lock the nuts against the brackets. (Fig.6E)
Horizontal mounting on the ceiling
Threaded rods, hanging brackets and ceiling
mounting brackets for ceiling mounting are
available as accessories, see accessories pages
and separate manuals.
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.
Unit without heating
Connected via the built-in control board with
1,5 m cord and plug.
Unit with water heating
Connected via the built-in control board with
1,5 m cord and plug.
Unit with electrical heating
The electrical connection is made on the
top of the unit. See Fig.2. The 3 kW unit is
connected via the integrated control card
using a 1,5 m cable and plug. Other units are
intended for permanent installation. Control
(230V~) and power supply for heat (400V3~)
should be connected to a terminal block in
the terminal box. 2-metre and longer units
require dual power supplies.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In
