INSTRUCTIONS
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.
