IMPORTANT FACTS

To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
S Your air conditioning system should never be operated without a
clean air filter properly installed. Plan to inspect the filter
periodically. A clogged air filter will increase operating costs and
shorten the life of the unit.
S Supply- -air and return- -air registers should not be blocked.
Drapes, furniture, and toys are some of the items commonly
found obstructing grilles. Restricted airflow lessens the unit's
efficiency and life span.
S Outdoor units must have unrestricted airflow. Do not cover the
unit, lean anything against it, or stand upon it. Do not allow
grass clippings, leaves, or other debris to accumulate around or
on top of the unit. Maintain a 12- -in. (30 cm) minimum
clearance between the outdoor unit and tall grass, vines, shrubs,
et cetera.
S Your multipurpose indoor thermostat is the control center for
your air conditioning system. You should familiarize yourself
with its proper operation. Attempting to control the system by
other means — for instance, switching the electrical supply
power ON and OFF — may cause damage to the unit.
