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
Mounting
The air curtain range can be adapted for
vertical or horizontal installation. The units
can also be installed recessed 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 PA34WB (fig. 6)
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 och 8 and
separate manuals.
Horizontal recessed mounting in false ceilings
Outlet extension used for recessed installation
is available as accessory, see fig. 10 and
separate manual.
PAEC5000-NA is developed to fit all
entrances. Recommended installation height
up to 5meters/16.4 feet.
The air curtain is available without heat and
with water heating.
Protection class: IP21.
Operation
Air is drawn in at the top/rear of the unit
and blown out downwards/outwards so that
it shields the door opening and minimizes
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 exhaust 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, 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.

Adjustment of the air curtain and air flow
The direction and speed of the air flow should
be adjusted considering the load on the
opening. Pressure forces affect the air stream
and make it bend inwards into the premises
(when the premises are heated and the
outdoor air is cold).
The air stream should therefore be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle that is needed.
Electrical installation
The installation, which should be preceded
by an omnipolar switch with a contact
separation of at least 3 mm/0.12 in, 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 with an integrated
control card, (see fig. 2).
SIRe is supplied pre-programmed with
quick-fit connections.
Modular cables are connected to the control
board. See manual for SIRe.
Unit without heating or with water heating
Connected via the built-in SIRe control board.
See wiring diagrams.
Vertical mounting PA4JK
Units from 1.5 metres/4.9 feet and longer may
be used vertically. For vertical mounting, all
units must be supplemented with a vertical
kit containing everything needed for a
practical installation of floor standing units.
The unit can be reversed and placed on
either side of the door. Connections and PC
Board SIRe are positioned near floor level
when the air curtain is placed to the left of
the door and at the top when it is placed to
the right (seen from the inside).
The accompanying floor edging is attached
to the floor with fasteners appropriate to the
surface.
Two units can be mounted directly on top of
each other, the floor edging is then used as a
joining bracket.
The air curtain must be secured to wall or
ceiling.
A design kit which gives a neater installtion
that conceals cables and pipes is available as
accessory, se accessories pages.
See fig. 11 and separate manual.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium fins and is suitable for connection
to a closed water heating system. Steel
connection pipe. The heating coil must not be
connected to a mains pressure water system
or an open water system.
Note that the unit shall be preceded by a
regulating valve, see Frico valve kit.
The water coil is connected on top of the
unit (horizontal mounting) or on the reverse
(vertical mounting) via connections DN20
(3/4’’), external thread. Flexible hoses are
available as an accessory, see accessories
pages.
The connections to the heating coil must
be equipped with shut off valves (included
in Frico valve kits) to allow problem free
removal.
A vent valve should be connected at a high
point in the pipe system. Air valves are not
included.
For vertical installation and bottom water
connection it is not possible to bleed the coil
in the unit. Ensure that the water coil is filled
with water and that no air remains, prior to
commissioning. See fig. 4.
Our recommended solution is to use a
T-connection and shut off valves. Small air
bubbles may remain, but will disappear with
normal operation. NOTE: Care must be taken
when connecting the pipes. Use a wrench or
similar to hold the air curtain connections to
prevent straining of the pipes and subsequent
water leakage during connection to water
supply pipe-work.

Basic setting fan speed
The fan speed when the door is open is set
using the control. Note that the air flow
direction and fan speed may need fine
adjustment depending on the loading of the
door.
Filter (W)
The water coil is protected against dirt and
blockage by an air filter which covers the
coil face. In environments where the filter
needs cleaning often, it is advisable to use an
external intake filter (see accessories pages),
which provides an easier maintenance, since
the unit does not need to be opened.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1.Disconnect the power supply.
2.Loosen the screws and raise the front panel.
The front is blocked in open position with
the front hatch hook, see fig 1A or removed
completely, see fig. 1B. The service hatch is
removed by loosening the screws.
3.After service, repairs and maintenance fasten
the service hatch and the front. When the
front has been removed it it important to be
sure it is firmly seated in the front locks again,
see fig. 1B.
Maintenance
Unit with water heating:
The appliance filter should be cleaned
regularly to ensure the air curtain effect and
the heat emission from the device. How often
depends on local circumstances. A clogged
filter is not a risk, but the appliance function
can fail.
1.Disconnect the power.
2.Loosen the screws and raise the front panel.
The front is blocked in open position with the
front hatch hook, see fig 1A.
3.Remove the filter and vacuum clean or wash
it. If the filter is clogged or damaged, it may
need to be changed.
Overheating
The air curtain unit with electric heater is
equipped with an overheat protector. If it is
deployed due to overheating, reset as follows:
1.Disconnect the electricity with the fully
isolated switch.
2.Allow the electrical coil to cool.
3.Determine the cause of overheating and
rectify the fault.
4.Connect the air curtain again.
All motors are equipped with an integral
thermal safety cut-out. This will operate,
stopping the air curtain should the motor
temperature rise too high. The cut-out
will automatically reset when the motor
temperature has returned to within the
motor’s operating limits.
Temperature control
Temperature control of SIRe maintains the
exhaust temperature. If the temperature
should exceed the preset value anyway
the overheating alarm goes off. For more
information see the manual for SIRe.
All units:
Since fan motors and other components are
maintenance free, no maintenance other than
cleaning is necessary. The level of cleaning
can vary depending on local conditions.
Undertake cleaning at least twice a year. Inlet
and exhaust grilles, impeller and elements
can be vacuum cleaned or wiped using a
damp cloth. Use a brush when vacuuming
to prevent damaging sensitive parts. Avoid
the use of strong alkaline or acidic cleaning
agents.
