General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The guarantee is only valid if the units
are used in the manner intended by the
manufacturer and in accordance with the
Frico mounting and operating instructions.
Application area
The RAR3500 air curtain unit is supplied
without heat, with electrical heating or hot
water coil and is intended for installation
above entrances and smaller doors up to 3.5
metres in height.
RAR3500 is recessed in false ceilings above
entrances.
Protection class: IP20
Operation
Air is drawn in from underneath and blown
out downwards towards the entrance so that
it shields the door opening and minimises
heat loss. To get the best 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 air speed is adjusted to the desired
airflow.
The efficiency of the air curtain(s) 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!
Installation
The air curtain unit is installed horizontally
with the supply air grille facing downwards as
close to the door as possible, concealed in the
false ceiling. The only visible part of the unit
is the underside that is level with the ceiling.
For the protection of wider doorways,
several units can be mounted next to each
other.
Ensure that the service hatch is accessible
and can be fully opened.
1.The mounting brackets are fixed to the unit
during transport. Slacken these off, turn
them around and screw into place on the
unit according to figure 1.
2.Hang up on threaded bars (M8) according to
figure 2a (not included).
3.Adjust the height using the lower nut so
that the frame is on the level of the ceiling.
Lock using the upper nut.
Mounting on threaded bars inside unit.
1.The mounting brackets are fixed to the
unit during transport. Loosen them and
screw them into place inside the unit in the
intended holes.
2.Hang up on threaded bars (M8) according
to figure 2b (not included). Note that
the brackets are at different heights and
threaded rods shall be of different lengths.
3.Adjust the height using the lower nut so
that the frame is on the level of the ceiling.
Lock using the upper nut.
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
aircurtain with an integrated control board,
(see fig 5).
PLS is supplied pre-programmed with quick-
release connections.
Modular cables are connected to the control
board, by opening the service hatch, as shown
in fig. 3 and 5. See manual for PLS.
1.The service hatch is opened by loosening
the snap fixings located on the down side
(turn 90°). See fig. 3.
2.RAR3500A: The unit is fitted with cable and
plug.
RAR3500W: The unit is fitted with cable
and plug.
Assembly and operating instructions

RAR3500
14
GB
RAR3500E: The unit is supplied through
cable glands on the side of the unit. For
units with electrical heating, power and
control should be supplied separately.
Control (230V~) and power supply for heat
(400V3~) should be connected to a terminal
block in the terminal box. 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”.
3. Close the service hatch and make sure that
the snap fixings lock properly.
See wiring diagrams.

Start-up
Note! When using for the first time or when
starting up after a long period of disuse, a
small amount of smoke and a slight odour
may occur temporarily, which is completely
normal.
Connecting the water coil (RAR3500W)
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. 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.
To access the connections (DN20, 3/4”,
inside thread) the service hatch and intake
grille must be opened. The water coil is
connected inside the unit through holes which
are made (during installation) on the upper
side or through the side of the unit, possible
places are marked with punch marks.
The connections to the heating coil must be
equipped with shut off valves to allow problem
free removal.
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 speed control. Note that the air flow
direction and speed may need fine adjustment
depending on the loading of the door.

with the hole diameter of the intake grille,
protects against dirt and blockage and makes
a separate filter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1.Disconnect the power supply.
2.The service hatch is opened by loosening
the snap fixings located on the down side
(turn 90°). See fig. 3.
3. After service, repairs and maintenance
close the service hatch and make sure that
the snap fixings lock properly.
Maintenance
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.Allow the electrical coil to cool.
3.Determine the cause of overheating and
rectify the fault.
Reset is performed as follows:
1.Locate the red button inside the air curtain
unit. It is visible and accessible by opening
of the service hatch and inlet grille. The
button is on the left side seen from inside
the room looking out. On the 2 metre
variant, two red buttons are installed in the
middle of the unit.
2.Press the red button until a click is heard.
3.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 at +40 °C. If the
temperature should exceed anyway there is
an over heating alarm. For more information
see the manual for SIRe.
Fan replacement
1.Determine which of the fans is not
functioning.
2.Disconnect the cables to the relevant fan.
3.Remove the screws securing the fan and lift
the fan out.
4.Install the new fan as above in reverse
order.
Replacing the electric heater/coil
(RAR3500E)
1.Mark and disconnect the cables to the
electric heater/coil.
2.Remove the mounting screws securing the
electric heater/coil in the unit and lift the
electric heater/coil out.
3.Install the new electric heater/coil in
reverse order to the above.
Replacing the water coil (RAR3500W)
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 (RAR3500W)
The drain valve is on the underside of the coil
on the connector side. It can be accessed via
the service hatch.
Trouble shooting
If the fans are not working or do not blow
properly, check the following:
•. Operating power supply to the unit;
check fuses, circuit-breaker, time switch/
thermostat (if any) that starts and stops the
unit.
•. That the air flow selector is correctly set.
•. That the position limit switch is working.
•. That the overheat protection for the motors
has not been deployed.
•. That the intake grille is not dirty.
If there is no heat, check the following:
•. That the heat demand exists; check
thermostat settings and actual temperature.
For units with electrical heating, check the
following:
•. 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 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
(applies to units with electric heater)
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! (RAR3500E)
• 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.
