ATTENTION INSTALLING PERSONNEL
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. Often during
installation or repair it is possible to place yourself
in a position which is more hazardous than when
the unit is in operation.
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 intended 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.
RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.
