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
RDS is intended for revolving doors. The air
curtain is available with electrical heating and
with water heating.
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.
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 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 horizontally on the
roof of the revolving door on steel plates (100
x 200 mm) that distribute the weight.
The unit could alternatively be mounted on
beams.
• Make sure that the air curtain fits 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 total weight of the installation
is stated in the Technical specifications. If
the roof of the revolving door cannot take
the weight, RDS can be mounted on a beam
construction. Mounting brackets for beam
included.
• Mounting with beam, 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 quick-fit
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 Fig.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. The service hatch is opened by unscrewing
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.

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 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 accessories, 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 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 coil plates in
combination with the hole diameter of
the intake grille protects against dirt and
blockage. This normally makes a separate
filter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
3. Disconnect the power supply.
4. Service hatch is opened by unscrewing 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
filter 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. If it is
deployed due to overheating, reset as follows:
5. Disconnect the electricity with the fully
isolated switch.
6. Allow the electrical coil to cool.
7. Determine the cause of overheating and
rectify the fault.
8. 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 anyway the overheating alarm
goes off. For more information see the manual
for SIRe.

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 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.
For units with electrical heating, also 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, also 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 (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 main 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!
• The unit may have hot surfaces during
operation and when cooling down!
• The unit must not be fully or partially
covered with clothing, or similar
materials, as overheating can result in a
fire risk! (E)
• Lifting equipment must be used to lift the
unit.
• 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
