. Mark the position of the bracket mounting holes
onto the wall. Remove the brackets and using a pre-
set depth drill, pre-drill holes to accept a wall anchor
(by others).
Failure to use a pre-set depth drill could result in serious
injury or death.
Note: It is preferred that the brackets are screwed
directly into a stud where available. However,
drywall anchors can be utilized when studs are
absent at bracket locations. It is the responsibility of
the installing contractor to provide the appropriate
fasteners and anchors to ensure that the unit is
secured properly.
