2. Installation

2.1 Fitting the controller

The control panel must be fitted onto a level surface with a minimum distance of 100 mm to any
corner.
The front cover is removed from the frame by twisting a screwdriver in the two holes on the sides
of the cover. The front cover can then be tipped carefully and the frame can be fitted onto the wall.
Fig. 3
NB:
The front cover is fitted with connection cable on the right side which limits how much this side
can be opened.
The controller covers a standard dry lining box (80 x 80 mm).
When fitting an external IR receiver avoid bending the black part of the cable
(EFC25 accessory)(Fig. 4).

2.2 Electrical wiring

!
• All installations must be carried out by competent personnel in accordance with
national legislation and regulations.
• An isolation switch must be installed between the controller and the chimney fan.
• Refer to the chimney fan instruction when installing the isolation switch.
• The isolation switch must be ordered separately as it is not part of the
standard exodraft delivery.
• Do not connect SMG terminals 6 and 7 to any valve other than an SMG valve supplied
by exodraft.
