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 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 with an integrated control card.
PLS is supplied pre-programmed with quick-
fit connections.
Modular cables are connected to the control
board. See manual for PLS.
Unit without heating or with water heating
Connected via the built-in control board PLS
with 1,5 m cord and plug.
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
PL2500 is intended for installation heights
up to 2.5 metres. 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 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.
Assembly and operating instructions

GB
Unit with electrical heating
The electrical installation is made on the
top of the unit, fig.2. Control supply (230V~)
and power supply for heating (400V3~) are
connected to terminal block in the internal
connection boxes. 2-metre 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
the distribution board it is to be indicated that
”the air curtains can be supplied from more
than one connection”.
See wiring diagrams.
Start-up (E)
When the unit is used for the first time or
after a long period of disuse, smoke or odour
may result from dust or dirt that has collected
on the element. This is completely normal
and disappears after a short time.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium louvres and is suitable for
connection to a closed water heating system.
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 valve kits.
The water coil is connected on the upper
side of the unit with ø15 mm smooth copper
pipe with a suitable coupling or soldering.
The connections to the heating coil must be
equipped with shut off valves (not included)
to allow problem free removal. Water coil is
equipped with a drain valve.
A vent valve should be connected at a high
point in the pipe system. Air valves are not
included.
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.
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.
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 internal air filter which covers
the coil face.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following
1. Disconnect the power supply.
2. The front hatch is removed by removing
the screws on the top of the unit and then
detach the bent edge at the bottom. (Fig.3)
3. After the service, repair and maintenance
reattach the front hatch. Place the hatch at
the lower edge with the bent edge and fasten
on top with screws.

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 supply.
2. The front hatch is removed by removing
the screws on the top of the unit and then
detach the bent edge at the bottom. (Fig.3)
3. Remove the filter and vacuum clean or
wash it. If the filter is clogged or damaged, it
may need to be changed.
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.
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. Determine the cause of overheating and
rectify the fault.
3. Remove the front hatch.
4. Press the red button located inside the
air curtain unit, at the inner gable of the
connection box.
5. Reattach the front hatch and connect the
unit 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 PLS maintains the
exhaust temperature to approx. +40 °C. If the
temperature should exceed anyway there is
an overheating alarm. For more information
see the manual for SIRe.
Replacing motor or impeller
1. Remove gable end.
2. Remove the screw between motor and fan.
3. Disconnect the cables to the motor.
4. Remove the screws securing the motor and
lift it out together with the impeller.
5. Install the new motor and/or the new
impeller as above in reverse order.
Replacing the electrical coil (E)
1. Mark and disconnect the cables to the
electric coil.
2. Remove the mounting screws securing the
electric coil in the unit and lift the electric
coil out.
3. Replace faulty electrical coil.
4. Install the new electric coil in reverse
order to the above.
Replacing the water coil (W)
1. Shut off the water supply to the unit.
2. Disconnect the connections to the water
coil.
3. Remove the mounting screws securing the
coil in the unit and lift the coil out.
4. Install the new coil in reverse order to the
above.
Draining the water coil (W)
The drain valves is on the underside of the
coil on the connector side. It can be accessed
via the front hatch.

Trouble shooting
If the fans are not working or do not blow properly,
check the following:
• That the intake grille/filter is not dirty.
• Functions and settings of the control
system PLS, see manual for PLS.
If there is no heat, check the following:
• Functions and settings of the control
system PLS, see manual for PLS.
For units with electrical heating, check also the fol-
lowing:
• Power supply to electric heater coil; check
fuses and circuit-breaker (if any).
• That the overheat protection for the motors
has not been deployed.
For units with water coil, check also the following:
• That the water coil is air free.
• That there is enough water flow.
• That incoming water is heated enough.
If the fault cannot be rectified, please contact
a qualified service technician.
Residual current circuit breaker (E)
When the installation is protected by means
of a residual current circuit breaker, which
trips when the appliance is connected,
this may be due to moisture in the heating
element. When an appliance containing a
heater element has not been used for a long
period or stored in a damp environment,
moisture can enter the element.
This should not be seen as a fault, but is
simply rectified by connecting the appliance
to the mains supply via a socket without a
safety cut-out, so that the moisture can be
eliminated from the element. The drying
time can vary from a few hours to a few days.
As a preventive measure, the unit should
occasionally be run for a short time when it is
not being used for extended periods of time.
Safety
• For all installations of electrically heated
products should a residual current circuit
breaker 300 mA for fire protection be used.
• Keep the areas around the air intake
and exhaust grilles free from possible
obstructions!
• During operation the surfaces of the unit
can be hot!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result in a
fire risk! (E)
• This appliance can be used by children
aged from 8 years and above and persons
with reduced physical, sensory or
mental capabilities or lack of experience
and knowledge if they have been given
supervision or instruction concerning
use of the appliance in a safe way and
understand the hazards involved. Children
shall not play with the appliance. Cleaning
and user maintenance shall not be made
by children without supervision.
