s a professional installer you have an obligation to know
A
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.
RECOGNIZE THIS SYMBOL
AS A SAFETY PRECAUTION.
