1. Decide how the system controller will be mounted: in the normal manner or flush with the
wall.
a) To mount the system controller in the normal manner, remove the mounting plate.
Then reattach the 4 screws to the electrical component box.
b) To mount the system controller flush with the wall, make an opening in the wall meas-
uring 128 mm x 128 mm. The opening must be at least 85 mm deep as measured
from the outside surface of the wall.
2. Remove the rear plate and connect the electrical wiring.
1) Remove the 4 screws located on both sides of the rear plate.
2) Either the hole in the top of the electrical component box or the hole in the rear plate
may be used to feed the electrical wiring.
3) If the hole on top is used, the rear plate should be turned upside down.
3. Secure the system controller in place.
a) If the system controller is being mounted in the normal manner, first attach the rear
plate to the wall using the screws and Rawl plugs provided. Next, place the body of
the system controller over the rear plate and secure it in place using four screws.
b) If the system controller is being mounted flush with the wall, fit it through the mount-
ing plate on the wall and secure it in place using the screws and Rawl plugs provided.
NOTE To mount the system controller on a wall made of cinder block, brick, con-
crete, or a similar material, drill 4.8 mm diameter holes in the wall and insert
Rawl plugs to anchor the mounting screws.
