IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Install in accordance with the manufacturer’s in-

SAFETY SYMBOLS
Labeling on products and the Installation Instructions &
User Manual may use safety related graphical symbols
as shown below to note safety requirements.
Lightning Bolt: The lightning flash with
arrowhead symbol, within an equilateral triangle,
WARNING symbol, is intended to alert the user to
the presence of un-insulated dangerous voltage
within the product’s enclosure that may be
sufficient in magnitude to constitute a risk of
electric shock to persons or domestic animals.
Exclamation Point: The exclamation point
within an equilateral triangle, CAUTION symbol,
is in-tended to alert the user to the presence of
important operating and maintenance (servicing)
instructions, or a hazard that can damage equip-
ment.
Do not proceed beyond a WARNING or CAUTION notice
until you have understood the hazardous condition and
have taken appropriate steps.
