Power mains parameters are stated on the unit packaging and/or the label on the unit casing.
Ingress protection rating against access to hazardous parts and water ingress is IP44.
The fan is rated for indoor operation at ambient temperatures ranging from +1 °C to +40 °C.
The unit is rated as the Class II (120 V, 60 Hz).
Power mains parameters are stated on the unit packaging and/or the label on the unit casing.

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.
Mark and drill the fan mounting holes, attach the insulation gasket, and install the fan.
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 the valve is prohibited.

11
The fan mounting sequence is shown in Fig. 4-12.
The fan wiring diagrams are shown in Fig. 13.
Terminal designations on wiring diagrams:
L— line S1 — external switch
N— neutral QF — automatic switch
S— timer control line
WARNING! The power cable may only be laid through the hole in the casing provided by the manufacturer
(Fig. 13). Laying the power cable through a manually drilled hole will not be the liability of the manufacturer
and will void the warranty. The wire must be stripped of insulation by a maximum of 8 mm (Fig. 13).
After installation, pass this user’s manual to the end user for reading.
The installation of the product is possible in the zones according
to the table below, provided that the installation and connection
are performed in accordance with the requirements of IEC
60364-7-701 (in the current version), as well as in accordance
with the requirements of the national standards of the country
of its installation.
Solid One/Wave One/Flip One/100 Solid Glass models may be
installed in Zone 1 of bathrooms where the product cannot be
exposed to water jets other than shower spray.
