CAUTION: Be sure that incoming power is turned off.
1. Position the Wall Canopy on it’s back and remove the filters.
2. Remove the Powered Liner (C2000) assembly from the canopy
shell by unscrewing the Four (4) mounting nuts with washers lo-
cated at each corner of the insert.
3. Install canopy shell to the wall by securing it to a minimum of two
(2) structural wall studs. Caution; Pre-Punched installation key
holes in the rear of the canopy to be used only if they line up with
the exiting wall studs. If needed, drill additional mounting holes
and secure to existing wall studs or remove the dry wall and install
proper backing to match pre-punched mounting holes.
Note: In the case of the “Rear Vented” series use the two vertical
support pieces on the back side to temporarily attach the canopy to
the wall. Locate the wall studs and using the four small (4) metal
mounting brackets secure the canopy to the wall.
