Mounting
Instructions for Wood
Walls
To wall mount the unit on a wood wall, follow these instructions:
1 Make two holes 150 mm (5.9 in.) apart.
2 Fix two suitable screws directly into the wall, leaving their heads 3 mm
(0.12 in.) clear of the wall surface. The screws should be at least 20 mm
(0.75 in.) long.
3 Remove any connections from the Switch and locate it over the screw
heads. When in line, gently push the Switch on to the wall and move
downwards to secure.
CAUTION: When making connections, be careful not to push the Switch
up and off the wall.
CAUTION: Only wall mount single units, do not wall mount stacked
units.
