WARNING!
The unexpected rotating impeller can crush fingers�
Before cleaning, isolate the fan from the mains power supply and protect against being switching on again!
– Clean casing and impeller with a damp cloth
– The motor must not come into contact with water!
– Do not use aggressive cleaning agents that could damage the paintwork!
– High pressure cleaners or water jets are not permitted!
All of the following information and instructions are intended solely for
authorised electricians!
6�1

Scope of delivery/Design

The SlimVent SV.. EC.. consist of a casing, an impeller and an EC motor mounted to the casing. There is a terminal box
on the outside for the connection of power and control lines. The scope of delivery includes an internal potentiometer in
the terminal box with which any fan speed between min. and max. speed can be set. With regard to types without an
external release or with an activated external release and a connected internal potentiometer (delivery 100%), the motor
will start automatically when the mains voltage is applied. For speed control, the internal potentiometer can be set to the
desired speed setpoint. For an external speed setting with a 0-10 V control signal, the internal potentiometer must be
removed. The fans are delivered as fully assembled units. Remove the unit from the box just before installation to prevent
any damage and contamination during transportation and on site.
m CAUTION
You can cut or scrape yourself due to sharp edges� Wear protective gloves when unpacking!

Installation preparation

m CAUTION
You can cut or scrape yourself due to sharp edges�
Wear protective gloves when checking unhindered running of impeller!
The fan is delivered as a complete unit as standard, i.e. ready for connection. It can be installed in any position. The
installation and commissioning of the fan should take place after the completion of all other works and after the final
cleaning, in order to prevent damage and contamination of the ventilation unit.
After the removal of packaging and the start of installation, the following points must be checked:
– is there any transport damage,
– broken or bent parts
– free movement of the impeller
When the impeller is turned by hand, there will be slight resistance due to the permanent magnets� This is for
technical reasons and it is not a malfunction�
6�3 Installation
The prevention of structure-borne sound transmission must be ensured during installation. In this respect, e.g. use pipe
clamp connectors BM.. in pipes or flexible mounting clamps FM.. (see section 3.3).
Mount unit to the wall or ceiling with the mounting device on the rear side. An elastic underlayer should be also
placed between the wall and unit to prevent structure-borne sound transmission. With regard to pipe ins-
tallation, it must be ensured that there is a sufficiently long straight pipe section (2.5 x D) before and
after the fan, as otherwise significantly reduced performance and noise level increases can be expected.
The terminal box must be mounted to the fan casing!

Electrical connection / Commissioning

m
DANGER!
Touching live parts will lead to electric shock�
Isolate the unit from the mains power supply before connection!
m
DANGER!
Waiting period of at least 5 minutes!
When using capacitors, there is a danger to life after deactivation due to the direct touching of live parts� Ter-
minal compartment access is only permitted after the power supply is disconnected and a 5 minute waiting
period�
6�4 Installation example: Suspended ceiling
When installing directly in pipeline, e.g. in suspended ceilings (see
Fig. 4), the units with small installation depths fit everywhere. Instal-
lation is possible in any position – horizontal, vertical and diagonal.
The hinged motor impeller unit (see Fig. 2/Fig. 3) allows simple
inspection and cleaning without removing components for both
series. The swing-out area must be taken into account for the unit
planning!
