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.
