Installer:
Ax all manuals
adjacent to the unit.
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
