Dimmer Switch
INSTALLATION
This WF500D dimmer switch may be used in new installations or replace an existing
wall switch.
MULTIGANG INSTALLATION
When installing more than one control in the same wall box, it may be necessary
to remove the side tabs before installing (see below). Using pliers, bend each tab
back and forth until they break off. Repeat for each tab to be removed. Removal
of tabs WILL REDUCE MAXIMUM LOAD CAPACITY.

 OPERATIONS
Air Gap Switch
Dimmer Switch Paddle
During normal operation, there is a small amount of power passing through the
switch to the load even when the dimmer switch is turned off. The WF500D has an
air gap switch on the lower right side to completely disconnect power to the load.
Slide the air gap switch to left to disconnect the power while replacing light bulbs
and slide it to right for normal operation. The air gap switch must be all the way in
for the dimmer to function and control the lighting.
