6.2.1.2. Mounting the SDO4 to
the header bracket
If you are on your own,
use a ladder to support
the control unit end of
the SDO4 while you are
positioning it for the next
step (Figure 19).
It is important at this point
of the installation to ensure
that the batteries are
connected before continuing
with the installation.
If after securing the header
bracket, it is slightly out
(not level), use a hammer
to knock the tabs gently up
or down with a small spirit
level placed on top of them.
This will ensure a perfectly
level installation (Figure 18).
