RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.
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 should
not supersede existing practices but should be
considered as supplemental information.
