INSIDE OF THIS LINE
UNIT OUTLINE
Be very careful when cutting this hole,
there is only a small amount of clearance
between the unit and the Mounting Holes.
Drill four 3mm (1/8") mounting holes at the indicated locations.
Install the four Mounting Studs into the unit by screwing the shorter section 
into the back of the unit.
Use a 1/16” (2mm) Allen Wrench to tighten the Mounting Studs until the 
stops contact 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 cutout in the mounting surface.
Place washers over the Mounting Studs, then thread on one Hex Nut per
Mounting Stud.
Tighten all four Hex Nuts 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 Hex Nut in place.
