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 RDS air curtain is supplied with electrical
heating or hot water heating.
RDS is intended for revolving doors.
The air curtain is installed above the
door and the exhaust duct is adapted to the
diameter of the door, which gives a neat and
discrete solution.
Protection class: IP20
Function
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 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 is installed, on steel plates
(100 x 200) that distribute the weight, on the
roof of the revolving door.
The unit could alternatively be mounted on
beams.
• Make sure that the air curtain ts on top of
the revolving door.
• The distance between the roof of the
revolving door and the inside ceiling must
not be less than 800 mm, for installation and
service to be possible.
• Ensure that the ceiling of the revolving door
can carry the weight of the air curtain and
duct. The estimated weight of the installation
is stated in the Technical specifications. If the
revolving door roof cannot take the weight,
RDS can be carried on a beam construction.
Beam mountings included.
• For installation with beams see fig. 2.
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.
SIRe is supplied pre-programmed with quickt connections. Modular cables are connected
to the control board.
See manual for SIRe.
Unit with water heating
Connected via the built-in control board with
2 m cord and plug.
Unit with electrical heating
The electrical connection is made on the side
of the unit.
Control (230V~) and power supply for heat
(400V3~) should be connected to a terminal
block. See g 1.
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.
1. Service hatch is opened by removing the
screws on the top side of the unit.
2. The unit is connected via the cable gland on
the right side of the unit (seen from inside).
See wiring diagrams.

GB
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. 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 the side
of the unit via DN25 (1’’), internal thread
connections.
Flexible hoses are available as an accessory,
see accessories pages.
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.
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
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 distance between the fins in combination
with the hole diameter of the intake grille
prevents the coil from clogging. This normally
makes a separate lter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance rst
carry out the following:
1. Disconnect the power supply.
2. Service hatch is opened by removing the
screws on the top or bottom side of the
unit.
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
lter is not a risk, but the appliance function
can fail. Vacuum the intake grille regularly
from outside when dust is visible, for example
as a part of the cleaning routine.
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. The
overheat protection is reset by turning
off the switch and the unit cools. 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 there is an overheating alarm.
For more information see the manual for
SIRe.

Fan replacement
Fans are replaced through the bottom service
hatch. Alternatively the screws of the bottom
service hatch are slackened and the fans are
replaced through the top service hatch.
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 electrical coil (E)
The coil must be replaced through the top
service hatch.

Replacing the water coil (W)
The coil must be replaced through the top
service hatch.
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.

For units with electrical heating, check also 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 also the following:
• That the water coil is air free.
• That there is enough water ow.
• 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.
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 service hatch.
Trouble shooting

check the following:
• That the intake grille/lter is not dirty.
• Functions and settings of the SIRe control
system , see manual for SIRe.
If there is no heat, check the following:
• Functions and settings of the SIRe control
system, see manual for SIRe.
