  Important Notes Please read before installing.
1. CAUTION: Use only with permanently-installed 120 V~ 
incandescent or halogen xtures. To avoid overheating and 
possible damage to other equipment, do not use to control 
receptacles, uorescent lighting xtures, motor-driven appliances, 
or transformer-supplied appliances.
2.  Install in accordance with all national and local electrical codes.
3.  Only one dimmer can be used in a 3-way circuit.
4.  When no “grounding means” exist within the wallbox then 
NEC
® 2008, Article 404.9 allows a dimmer without a grounding 
connection to be installed as a replacement, as long as a plastic, 
noncombustible wallplate is used. For this type of installation, 
cap or remove the green ground wire on the dimmer and use an 
appropriate wallplate such as Lutron's Claro
® or Fassada® series 
wallplates.
5.  For new installations, install a test switch before installing the 
dimmer.
6.  Protect dimmer from dust and dirt when painting or spackling.
7.  Recommended minimum load is 40 W.
8.  It is normal for the dimmer to feel warm to the touch during 
operation.
9.  Clean dimmer with a soft damp cloth only. Do not use any 
chemical cleaners.

Multigang Installations
When installing more than one control in the same wallbox, 
it may be necessary to remove all inner side sections prior 
to wiring (see diagram). If pre-installed, remove the Lutron 
wallplate and wallplate adapter from dimmer. Using pliers, 
bend side section up and down until they break off. Repeat 
for each side section to be removed. Removal of dimmer 
side sections reduces maximum load capacity. Refer to chart 
below for maximum dimmer capacity.
