Deciding the wiring route
• You have a choice of whether to feed the electric cable
through the side or through the back of the unit.
• If it going through the side of the unit, cut out the
plastic lug to expose the grommet (diagram 2).
• If is going through the back of the unit, cut through the
grommet on the backplate with a sharp knife (Take Care!).
Make sure you do not remove the grommet from the backplate (diagram 3).
Feed the cable through the grommet before you fix the unit to the wall.
Fixing to the wall
• Undo the retaining nuts and take the front cover
off the unit. Hold the backplate in position against
the wall whilst you mark the four fixing holes.
• Drill the holes and fix the unit to the wall using the
four No.8 x 38mm wood screws supplied.
