Electrical Wiring
• Electrical installation must be carried out by an
authorised electrician.
• The fan is double insulated and should not be grounded.
• The fan is fitted with a multi-pole switch and does not
require a pre-wired external switch.
Installation Options
The fan can be connected in three different ways depending on the desired function.
The fan is connected with constant voltage supply 100 -240 VAC 50/60 Hz, phase (L) and Zero (N), see wiring diagram
• Time control with light switch, see wiring diagram 2. The fan is connected with constant voltage supply 100 -240 VAC
50/60 Hz, phase (L) and Zero (N). The control phase (SL) is connected to activate the fan’s time control, i.e. when the
bathroom light comes on, there is power to the igniter wire. This option provides a delayed start of 2 minutes. The fan
will run as long as the light is lit. When the light goes out, the fan will run for another 15/30 minutes.
• Time control with spring-loaded switch, see wiring diagram 3. The fan is connected with constant voltage supply
100 -240 VAC 50/60 Hz, phase (L) and Zero (N). The control phase (SL) is connected to activate the fan’s time control
with spring-loaded switch. The fan runs for 15/30 minutes after the spring-loaded switch has been activated.
