3. Hold the back can in place in the ceiling, while tightening the
mounting clamp screws clockwise (Fig. 18). Do this systematically
until all eight clamps are in position and holding the back can
securely to the ceiling drywall.
Painting
1. A paint mask is supplied to protect the back can from paint, dust,
and debris. It allows you to paint and fi nish the ceiling after the
installation of the back can.
2. Press the paint mask into the front of the back can, where it will be
kept in place by magnets. This mask is left in place while the ceiling
and frame surround is painted (Fig.19).
3. It is strongly recommended that the metal perforated grille is sprayed
separately, as this will avoid clogging of the holes. If painting with a
brush is the only option, then several thin coats of paint will provide a
superior fi nish to that achieved by one applied too thickly.
Installing the Loudspeaker
1. Remove the paint mask from the back can.
2. Note that loudspeaker assembly will only fi t into the back can in one
way: the connector on the rear of the loudspeaker assembly must
align with the matching connector on the back can.
3. Install the loudspeaker into the back can and secure it in place with
the screws (Fig.20).

Grille Installation
1. The grille should be carefully fi tted by lining up the edges of the grille carefully
with the baffl e and frame inside edges (Fig. 21). To avoid indentation damage, do
not press the centre of the grille; apply even pressure to each corner as it is pressed
fi rmly into position.
2. To remove the grille, loop an opened paper clip or similar length of firm wire,
through two holes near a corner and pull gently. The grille is intended to be
a tight fit, so insert the wire at each corner in turn, pulling carefully to avoid
distortion of the mesh.
System Testing
1. Switch on the amplifi er with the volume control at its lowest setting. Select a
suitable signal source and slowly turn up the volume to a low level. Check that the
loudspeaker is working correctly and is in phase - if not, switch off the amplifi er
and recheck the connections.
2. Carefully check the area surrounding the installation and listen carefully to ensure
that there are no buzzes or rattles that could potentially impair enjoyment of the
system. If there are, then locate and silence the causes using cable ties or suitable
packing material.
