DEHUMIDIFIER INSTALLATION
Step 11.
Insert the dehumidifier into the center of the opening,
allowing for a minimum of 1/8
"
clearance from framing on both
sides. Additional insulation or sound dampening material (not
provided) may be required if the dehumidifier cabinet contacts
the studs, especially in applications involving metal studs.
Fasten the unit to the framing by inserting four of the #10
(wood) or #8 (sheet metal) screws into the slotted holes.
Top and bottom blocking is not necessary for securing the
dehumidifier. Any existing blocking, headers or framing
should not intrude into the rough opening and be a minimum
of 1/2
"
away from the cabinet.
The cabinet is designed to create 1/2
"
clearance to the back
wall when installed inside a standard 2x6 stud space with
1/2
"
minimum drywall sheathing.
For alternate installations, maintain 1/2
"
clearance to back
of wall of dehumidifier cabinet.

Before securing the unit into place, make sure it is level. Level
or slightly forward is acceptable, but never backwards.
