RECOGNIZE

THIS SYMBOL

ATTENTION

AS A SAFETY

PRECAUTION.

INSTALLING PERSONNEL

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 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.

FACTOR

to international

The carton

Carbon monoxide producing devices (such as an automobile, space
heater, gas water beater, etc.} should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions.
If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
