INSTALLATION INSTRUCTIONS
ATTENTION INSTALLING PERSONNEL
As a professional installer, you have an obligation to know the
product better than the customer. This includes all safety pre-
cautions 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 be-
fore 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.
