Installation
Back Box Installation:
1. Determine if the unit is to be surface or flush mounted. If flush mounted, the front edge of the Back Box
should be flush with the wall’s finish surface.
2. The Back Box must be securely attached to the wall.
3. Connect the mains wiring to the Back Box with Hot, Neutral, and Ground following local electrical codes. If
the conduit does not provide the safety ground, a mains ground wire must be attached to the ground stud
located close to the terminal block with the lock washer and nut provided.
Note: For side mounting into studs, use a quantity of 8- #10 or equivalent fasteners, 4 on each side. For rear mounting, use a
quantity of 4- 1/4” or equivalent fasteners. The fasteners must be of an appropriate type for the material the unit will be attached
to. Installation shall be conducted by a skilled person or professional.
