UNIT OUTLINE

CUT MOUNTING SURFACE ALONG
THE INSIDE OF THIS LINE

Be very careful when cutting this hole,
there is only a small amount of clearance
between the unit and the Mounting Hole.

Drill four 3mm (1/8") mounting holes at the indicated locations.
Install the four Mounting Studs into unit by screwing the shorter section
in to the back of the unit.
Use a .050" Allen Wrench to tighten the Mounting Studs until the
stop contacts the case. Be careful not to overtighten as this may damage the
Mounting Stud! The studs have a reusable thread-locking patch pre-applied
from the factory.
Place the unit in position in the cut out in the mounting surface.
Place washers over the Mounting Studs, then thread on one Hex Nut per
Mounting Stud.
Tighten all four until the unit is snug against the mounting surface.
Install and tighten the second Hex Nut on all four Mounting Studs to lock
the first one in place.

DRILL A 3/8" HOLE.
