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.

Description
