MOUNTING
The fan is designed for wall (with the motors on ball and slide bearings) or ceiling (with the motors on ball bearings only, L
option) mounting and can be used for direct outdoor air exhaust through a round duct or a duct system.
In case of installation through a duct system, select the duct cross section in accordance with the fan size (Fig. 1).
1. When installing the fan with direct air discharge outside through the wall, be sure to install a ventilation grille with louvre
shutters or a ventilation hood on the outside to prevent rainfall, snow, leaves, branches, etc. from entering the duct.
To reduce the risk of condensate forming in the duct, the space between the hole in the wall and the duct must be insulated.
Install the air duct with the minimum slope of 1...2° downwards to the outer wall side for condensate removal (Fig 2).
2. The duct system should not exceed 5 meters and have more than two bends.
3. During ceiling installation, vertical air discharge upwards is not allowed even if there is a protective outer hood on the roof.
For ceiling mounting and air discharge to the roof, the duct system must include a condensate drain (Fig. 3).
A condensate drain is not included in the delivery set of the fan and can be ordered separately.
Check the fan for any visible damages of the impeller, the casing and the grille before starting installation. The casing internals
must be free of any foreign objects which can damage the impeller blades.
While mounting the unit, avoid compression of the casing!
Deformation of the casing may result in the motor jam and excessive noise.
Mount the fan on the wall or ceiling using four dowels with screws (included in the delivery set).
Dowels and screws are designed for concrete and brick walls.
If the walls are made of the other material (drywall, wood,etc.), use the fasteners appropriate for these materials to fasten the
fan (not supplied with the fan and must be purchased separately).
WARNING! When the fan is equipped with a non-return valve, operation of the fan without this valve is prohibited.

The fan mounting sequence is shown in Fig. 4-11.
The fan wiring diagrams are shown in Fig. 12-14.

L: line S: external switch
N: neutral QF: double pole circuit breaker
LT: timer control line
WARNING! The power cable may only be laid through the hole in the casing provided by the manufacturer.
Laying the power cable through a manually drilled hole will not be the liability of the manufacturer and will void
the warranty. The wires must be stripped of insulation by a maximum of 8 mm.
After installation, pass this User’s manual to the end user for reading.
