Specialty Concepts SC3/20 - Manual (Page 6)

INSTALLATION INSTRUCTIONS:
1. MOUNTING CONSIDERATIONS: - The SC3/20 is designed to be mounted flush against a
wall. It can be mounted onto a wall by adding the optional knockout box (4x7 BOX). Flush
mounting or wall mounting require different installation and mounting considerations.
FLUSH MOUNT: The flush mounted unit requires a rectangular cut-out in the mounting
surface with sufficient space (2-3 inches) immediately behind to accommodate the
controller. Electrical connection is made to the back of the controller via wires.
WALL MOUNT: The wall mounted unit (SC3/20 with the 4x7 BOX) is installed onto a wall
surface via four mounting screws. Electrical connections are made through knockouts
in the box to the wires on the back of the controller.
