SILENT Axial Extractor Fans

The SILENT extractor fan ranges are manufactured to the high standards of production

and quality as laid down by the international Quality Standard ISO 9001. All components

have been checked and every one of the final products will have been individually

tested at the end of the manufacturing process.

On receipt of the product we recommend that you to check the following:

1- That it is the correct size.

2- That it is the correct model.

3- That the details on the rating label are those you require: voltage, frequency...

Installation

The installation must be carried out in accordance with the electrical standards in force

in your country.

This fan is IP45 rated and it is suitable for application in zones 1 and 2 with RCD

protection.

IMPORTANT: Before installing and wiring the unit, ensure that the main supply

is disconnected.

Fig. 1 / 1b:

1: Protection grille

2: Connection terminals

3: Outlet with backdraught shutter

4: Cable entry

5: Screwdriver to adjust Timer and Hygrostat (not supply with S and P models)

6: Pullcord (P models)

The SILENT is suitable for wall or ceiling mounting and can either discharge directly to

the outside or via an individual ducting system (see Fig. 2).

The unit should be mounted on the wall or ceiling using the 4 rawl plugs and screws

provided.

Make a hole in the wall or ceiling of diameter:

SILENT-100: 105 mm

SILENT-125: 125 mm

SILENT-150: 160 mm

If the unit is to be installed with individual ducting, use a standard duct of diameter:

SILENT-100: 100 mm

SILENT-125: 125 mm

SILENT-150: 150 or 160 mm

Ensure that there are no obstructions to the airflow and that the impeller turns freely.

Fix the extractor to the wall in such a way that it is not distorted in order to avoid noise

generation or problems with the rotation of the impeller. Make sure that the backdraught

shutter opens freely and has not being damaged in transit. Introduce the mains cable

through the cable entry (4) and fix it to the wall.

Connect the electrical wiring as set out below and then mount the protection grille (1).

Electrical connection

The SILENT is an extractor designed for a single phase supply, with voltage and

frequency as indicated on the rating plate of the unit. The units are manufactured with

double electrical insulation (Class II) and therefore they do not need an earth

connection.

The electrical installation must include a double pole switch with a contact clearance of

at least 3 mm.

The electrical cable must enter the SILENT through the cable entry (4).

The SILENT must be connected to the electrical supply in accordance with local wiring

regulations.

Once the cable has been introduced proceed using the electrical wiring diagram

applicable to the selected model.

SILENT S

For these models use the following diagrams:

Fig.3: Switching the extractor through the light switch.

Fig.4: To switch the fan through an independent switch.

SILENT T

This model is provided with an adjustable over-run timer. The timer allows the fan to

continue to operate for the selected period after the switch has been turned off (fig.6).

Fig.5 shows how to connect the fan with timer utilising the same switch as for the

lighting circuit.

To set the timer, turn the potentiometer on the printed circuit board as (fig. 7).

- To reduce the "run on" time, turn anticlockwise (min. 1 minute)

- To increase the "run on" time, turn clockwise (max: 30 minutes).

SILENT-100 IT (this version is only available as SILENT-100)

This model is provided with an adjustable over-run timer. The timer allows the fan to

continue to operate for the selected period after the switch has been turned off (fig.6).

ATTENTION: The product also includes an over-run timer facility that

starts the fan after the first 50 seconds of non-operation. After these first 50

seconds the fan operates automatically.

SILENT HT

IMPORTANT:

Do not remove the tape covering the humidity sensor located on the reserve

of the grille.

Models provided with an electronic humidistat which can be adjusted from 60% to 90 %

RH (relative humidity) and with a timer, adjustable between 2 and 20 minutes.

Operation

Case 1: Automatic operation (fig.9)

In automatic operation, the humidistat causes the extractor to operate automatically

when the humidity level in the room is higher than the set level. The extractor will stop

automatically when the humidity drops below the selected level and after the selected

period set on the timer.

Case 2: Automatic operation as in case 1 with the facility to override the humidistat by

means of the light switch (fig.8), when the humidity level in the room is lower than the

selected level. In this case, the extractor continues to operate for the selected period

set on the timer after the switch light has been switched off.

ATTENTION: When the humidity rate is above the selected value, the

automatic option takes precedence over the manual and the unit cannot then

be switched off using a switch.

The desired humidity level is selected by means of a potentiometer “% Hr”positioned on

the printed circuit board (fig.10) and accessible once the grille (1) has been removed.

- To increase the humidity setting turn anticlockwise (min.60 %)

- To reduce the humidity setting turn clockwise (max. 90 %)

To set the timer, turn the potentiometer “t min.”on the printed circuit board (fig.10):

- To reduce the "run on" time, turn anticlockwise (min. 2 minutes)

- To increase the "run on" time, turn clockwise (max: 20 minutes).

SILENT-100 PIR (this version is only available as SILENT-100)

Models provided with a PIR (passive infra-red) detector. The unit starts automatically

when a movement is detected with a maximum distance of 4 metres (fig.9).

They are also fitted with an adjustable "run on" timer (1 to 30 minutes), and the unit will

continue to operate for the set period after initiation by the movement detector.

To set the temporisation, turn the potentiometer on the printed board (fig.7):

- To reduce the "run on" time, turn anticlockwise (min. 1 minute)

- To increase the "run on" time, turn clockwise (max: 30 minutes).

SILENT-150 P and HTP (these versions are only available as

SILENT-150)

Models provided with on/off pullcord switch use the following wiring diagram:

Fig.11 –SILENT operated only with the pullcord

Maintenance

The extractor fan only requires periodical cleaning using a cloth lightly impregnated with

a soft detergent.
