Attention Installing Personnel

As a professional installer, you have an obligation to know the prod-

uct 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.

SAFETY CONSIDERATIONS

The following symbols and labels are used throughout this manual 

to indicate immediate or potential safety hazards. It is the owner’s 

and installer’s responsibility to read and comply with all safety 

information and instructions accompanying these symbols. Failure 

to heed safety information increases the risk of personal injury, 

property damage, and/or product damage.
