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.
This manual must be left with the owner of the equipment.
