s 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.

RECOGNIZE THIS SYMBOL

AS A SAFETY PRECAUTION.
