1 Important Safety Instructions
As a professional installer, you have an obligation to know
the product better than the customer. This includes all safety
precautions and related items. Prior to actual installation,
thoroughly familiarize yourself with this Instruction Manual.
Pay special attention to all safety warnings. Remember, it is
your responsibility to install the product safely and to know it
well enough to be able to instruct a customer in its safe use.
Safety is a matter of common sense...a matter of thinking before
acting. Most dealers have a list of specific, good safety
practices...follow them.
The precautions listed in this Installation Manual are in- tended
as supplemental to existing practices. However, if there is a
direct conflict between existing practices and the content
of this manual, the precautions listed here take precedence.
