For your safety, every fan is factory-tested before leaving production.

DUKA S8
The S8 is a multi-function fan that can be installed in bathrooms, living areas (with eight ventilation solutions) or used as an energy-saving heat mover. With the unique function selector, it is simple to change the function. Lift the round front cover and select the function.

Bathroom extractor fan (with eight selectable functions)
S8 has eight selectable functions for ventilation tasks in all residential properties with natural ventilation. It is designed and approved for use in the home's wet rooms (IP44).
Mounted on exterior wall or ceiling (separate and well-insulated duct Ø80 – 125 mm).

Heat transfer – save energy
S8 has a built-in electronic thermostat that controls the fan to move excess heat from, for example, a living room with a wood-burning stove to an adjoining room.

Don't forget the air supply
To achieve good and optimal ventilation in the room, you must also ensure:
– Air supply to the wet room, e.g. via a gap under the door, or another vent/grille.
- Fresh air enters the room, for example via telescopic vents.

Dimensions

Technical data

Installation

NOTE: The fan is intended for fixed installation and must be connected by an authorised electrician.

Preparations

Ensure that the pipework is insulated. If it is not insulated with at least 50 mm of insulation, the following may occur:
condensation that can drip down into the extractor fan and cause a short circuit.

Placement of ventilator

The fan must be installed in accordance with the applicable regulations for electrical installations in wet rooms. Find out more at SIK.dk
and the QuickGuide.

Preparing fan

The motor unit has a bayonet fitting, which makes it easy to set up and clean.
1. Grasp the front and turn anti-clockwise. Lift the motor unit off the wall bracket.
2. The cover of the wall frame is held in place by 3 screws (PH1). Loosen the screws and remove the cover.
3. If the cable is to be routed through the top of the front panel, a hole must be made in the front panel for the cable. Here, a thinner section has been cut out of the cover so that
is cut off. Use the square piece in the cardboard template to mark out the cutout for the best result.

Assembly of the wall frame

1. Mark the holes using the supplied template.
Drill holes and insert wall plugs into the holes
3. Screw the wall frame firmly to the surface (PH2 x3). Ensure the ”UP” marking points upwards for wall mounting.

Electrical connection

Please note! Must be connected by a qualified installer. For all electrical work on the fan, the power supply must be disconnected.
The fan is designed for 230 V AC, 50 Hz. Double insulated, must not be connected to earth.
1. Run the cable to the XP1 junction box
– The fan can also be connected to 12V via the XP2 connector. Do not connect power to both.

Seals

To prevent water from entering the engine, the partition frame has several integrated seals (seal with silicone, for example, if necessary):
1. On the reverse side, seal against the substrate.
2. At the cable entry point.
3. At the screw bushings (3 in total). Note: Any gap between the bushing and the ventilation pipe must be sealed.

Fit cover and front

1. Screw the lid on
2. Fit the front and turn clockwise until the front is locked in the bayonet fitting.
3. Switch on the power

Switch

The fan is delivered switched off with the switch so that ”OFF” is visible. The fan is activated by sliding the switch so that ”ON” can be seen.

According to the EN 60335-1 standard, the fan must be capable of
disconnected from the mains electricity supply. This is fulfilled by the built-in
switch (2-pole, 3 mm contact gap).

Functions and features

DUKA S8 has 8 functions which are created from the 4 available built-in sensors. Not all sensors are active at all times. See which functions are available
activated in every function in the next section. Functions 1-4 include background ventilation and are the recommended functions for a bathroom.

The built-in sensors are:

– Humidity sensor that sends a signal to the device when there is a major change in relative humidity.

– Temperature sensor that sends a signal to the device when the room temperature reaches 28°C, and turns off again when the room reaches 24°C.

– Motion sensor that sends a signal when there is movement in front of the device.

– A light sensor that sends a signal to the device when there is a sudden change in the light levels in the room.

The functions are selected using the position button located on the inside of the front panel.
Remove the front as indicated in the drawing and turn the position knob using the dedicated tool supplied with the unit.

Job descriptions

Features with background ventilation

Function 1: Low-level basic ventilation with motion and humidity control

The fan operates at a basic ventilation rate of 20 m³/h.
If the motion or light sensor is triggered, the fan switches to
60 m³/h with a delay of 30 seconds.
When there is no longer a signal from the motion or light sensor, the following will occur:
The fan will continue to run at a rate of 60 m³/h for 15 minutes.
If the humidity sensor is triggered, the fan switches to 90 m³/h. If the humidity falls
If the humidity rises again, switch the fan back to basic ventilation at 20 m³/h
unless there is still a signal from one of the other sensors. In that
In this case, the sensors will take over and the fan will run at 60 m³/h
with a 15-minute cool-down.

Function 2: Background ventilation with motion and humidity control

The fan operates at a basic ventilation rate of 40 m³/h.
If the motion or light sensor is triggered, the fan switches to
60 m³/h with a delay of 30 seconds.
When there is no longer a signal from the motion or light sensor, the following will occur:
The fan will continue to run at a rate of 60 m³/h for 15 minutes.
If the humidity sensor is triggered, the fan switches to 90 m³/h. If the humidity falls
the humidity has changed the fan back to baseline ventilation 40 m3/h
unless there is still a signal from one of the other sensors. In that
In this case, the sensors will take over and the fan will run at 60 m³/h
with a 15-minute cool-down.

Function 3: Basic ventilation with humidity control

The fan operates at a basic ventilation rate of 40 m³/h.
If the humidity sensor is triggered, the fan switches to 115 m³/h. If the humidity falls
Once the humidity has returned to normal, switch the fan back to basic ventilation 40
m³/h. Signals from other sensors are ignored.

Function 4: High basic ventilation with humidity control

The fan operates at a basic ventilation rate of 60 m³/h.
If the humidity sensor is triggered, the fan switches to 115 m³/h. If the humidity falls
Once the humidity has returned to normal, switch the fan back to basic ventilation 40
m³/h. Signals from other sensors are ignored.

Functions with standby

Function 5: Standby mode with motion and humidity control

The fan remains stationary in standby mode until it receives a signal from a sensor.
If the motion or light sensor is triggered, the fan switches to
60 m³/h with a delay of 30 seconds.
When there is no longer a signal from the motion or light sensor, the following will occur:
The fan will continue to run at a rate of 60 m³/h for 15 minutes.
If the humidity sensor is triggered, the fan switches to 90 m³/h. If the humidity falls
The humidity switches the fan off in standby mode unless there is still
is a signal from one of the other sensors. In that case, those sensors
switch on and the fan will run at 60 m³/h for 15 minutes
chase.

Function 6: Standby mode with motion and humidity control + ventilation for 30 minutes every 12 hours

The fan remains stationary in standby mode until it receives a signal from a sensor.
If the fan has not received a signal for 24 hours, the fan will run
at a rate of 20 m³/h for 30 minutes every 12 hours until it receives a signal from a sensor.
If the fan receives a signal from one of the sensors, it will run as
Function 5.

Function 7: The fan remains stationary in standby mode until it receives a signal from a sensor.

If the temperature sensor is activated, the fan switches to 90 m³/h, and
stops again when it no longer receives a signal from the sensor.
The temperature sensor starts when the temperature reaches 28°C and stops
Yes, at 24°C.

Function 8: Standby mode with humidity control

The fan remains stationary in standby mode until it receives a signal from a sensor.
If the humidity sensor is triggered, the fan switches to 115 m³/h. If the humidity falls
the humidity has switched the fan back to standby mode.

Maintenance

The fan must be maintained at least once every 6 months.

• Remove the front panel and wipe the fan parts with a dry cloth and/or a soft brush.

• Reinstall the front panel on the cooker hood.
