Flat Centrifugal Fan Boxes – SlimVent SV..
All of the following information and instructions are intended solely for
authorised electricians!
6.0

Scope of delivery/Design

The SlimVent SV.. fans consist of a housing, an impeller and an electric motor attached to the housing. There is a
terminal box on the outside for the connection of power and control lines. The fans are delivered as fully assembled
units. Remove the SV unit from the box just before installation to prevent any damage and contamination during trans-
portation 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
6.2 Installation
The prevention of structure-borne sound transmission must be ensured during installation. In this respect, e.g. use pipe
clamp connectors BM.. or Flexible sleeves FM.. (see accessories section 3.1) between the ducting. 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 installation, 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 ter-
minal box must be mounted to the fan casing.
NOTE!
Full fan performance can only be achieved with free inflow and outflow.
Sufficient motor cooling must be ensured, so that there is a minimum air flow area of 20 % for the fan cross-section.
6.3

Installation example: Suspended ceiling

When installing directly in pipeline, e.g. in suspended ceilings (see Fig.4), the units with small installation depths fit ever-
ywhere. The unit must be installed with the inspection opening facing downwards or to the side. Installation with the
inspection opening facing upwards is not permitted and IP protection will expire in this case.
The hinged motor impeller unit (see Fig. 2/3) allows simple inspection and cleaning without removing components. The
swingout area must be taken into account for the unit planning.

Electrical connection / Commissioning

m
WARNING!
Touching live parts will lead to electric shock.
Isolate the unit from the mains power supply before connection!
m
DANGER!
The rotating impeller can crush fingers.
Ensure protection against contact before commissioning!
