Dimensions - Standard Models • Ensure mounting can support 6.5 lbs (2.95 kg) plus any additional, foreseeable load. • Ensure that none of the electrical connection circuits are live. Mounting Without Optional Mounting Plate • Use the appropriate template to locate and drill holes for mounting screws. See: Figure 2 - Overall Use #10 or M5 screws to secure the unit to the wall. Use anchors in plaster Dimensions - Standard or cement to provide a firm grip for the mounting screws. Use sturdy hollow- Models wall fasteners to mount the set to drywall. • Loosen the five captive screws in the faceplate and swing the faceplate to the left.
