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
N
– neutral
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.
L1
– terminal for air supply
L2
– terminal for air extraction
10
S
– external switch
QF
– automatic circuit breaker
