The unit is an extract fan (VV models) and a supply and extract fan (VVR models) and is designed for wall or window mounting.
The fans of the VVR series are equipped with a reversible motor for the possibility of combining air supply and air extraction.
The fan is rated for continuous operation.
The fan has automatically opening shutters driven by a motor-reducer.
The fan design is constantly being improved, thus some models may be slightly different from those described in this
manual.

DESIGNATION KEY

MOUNTING AND SET-UP
Prepare a hole D1 in the wall or glass:
• for VV, VVR 180 fans – D1=192–194 mm,
• for VV, VVR 230 fans – D1=250–254 mm.
Insert the fan into the hole and fix it using the clamping plates or screws that fix the fan casing to the wall through the
dowels (Fig. 3). Install the outer fan panel.
CONNECTION TO POWER MAINS
The fan is rated for connection to single-phase AC 220-240 V/50 (60) Hz power mains.
Terminal designations on the wiring diagrams:
L– line L1 – terminal for air supply S– external switch
N– neutral L2 – terminal for air extraction QF – automatic circuit breaker
When using a reversible VVR fan, the air flow direction is reversed.
To connect a fan with a reverse direction, you can use the external switch S shown in Fig. 4, or perform internal wire switching:
- when a phase is applied to terminal L2, the fan operates in the air extraction mode
- when a phase is applied to terminal L1, the fan operates in the air supply mode
The wiring diagram of the VVR fan is shown in Fig. 4.
