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.
