CENTURION SYSTEMS SDO4 SMART Installation Manual page 29

SECTION 6
The two towing arms must
be joined in such a way
that they are just short of
parallel to the garage door
and the ceiling.
Angle 'Z' should be ±80°
when the garage door
is in the closed position,
as shown in Figure 41.
This will put less strain
on the motor on start-up
and, furthermore, aid in
preventing the garage door
from being forced open by
hand.
Once aligned, secure the towing
arms into position using the two
supplied hexagonal head flange
nuts and bolts: one set through the
bottom hole of the straight towing
arm, and the other through the top
hole of the bent towing arm.
Please do not forget to affix
the safety sticker and tag.
The SDO4 SMART is now
installed and ready for
programming.
