Installation
 Make a  185 mm hole in the wall.
 Push the telescopic wall pipe into the
hole so that it is sitting flush.
The telescopic wall pipe will make it
easier to feed the control cable and
the flexible ducting through later on.
 Position the motor unit bracket on the
outside wall. The control cable
connection must be at the bottom.
 Mark the position of the 3 holes to be
drilled.
 Drill three 8 mm  holes and insert

the telescopic wall pipe into the
house.
 If equipotential bonding is required,

provided in the motor unit bracket.
Equipotential bonding is required if
the control cable is to be extended
