Miele DA239-3 installation instructions Inserting the non-returnflap, Installation

Installation

^Drill the 4 marked holes for the upper and lower retaining plates using a 1/8" (3 mm) diameter bit.

^Screw the upper and lower retaining plates securely to the wall.

^Screw the 2 motor assembly support screws into the marked locations.

Allow the screw heads to protrude about 1/4" (5 mm) so the motor can hang on them.

Inserting the non-return flap

^Place the non-return flap into the exhaust connection at the top of the motor assembly so that the flaps open in the "up" direction.

^Turn the non-return flap slightly to lock it in place.

^The hood is designed for use with 6" (150 mm) ductwork.

If 5" (125 mm) ductwork is to be used a reducing collar must be installed. (see "Air extraction").
