ALONG INSIDE OF THIS LINE

UNIT OUTLINE

DRILL A 3/8" HOLE.   

BEGIN CUTTING HERE.

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 unit by screwing the shorter section in to 

the back of the unit. 

Use a 1/16” (2mm) 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.
