IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
• 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.
• 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.
• The outdoor unit 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
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

the unit. Maintain a 12-in. minimum clearance between the
outdoor unit and tall grass, vines, shrubs, etc.
• 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.
• Thermostat "jiggling" causes rapid-cycling, which is potentially
damaging to the compressor. Do not move the temperature selector
on the thermostat for any reason for at least 5 minutes after the
compressor has shut off.
• You may find that you can maintain greater personal comfort by
running the fan continuously. "Air pockets" can form due to the
structure of the house, placement of registers, etc. These air
pockets may be too cool or warm for you liking. Continuous fan
operation minimizes any temperature differences. Also, systems
equipped with electronic air cleaners and/or humidifiers offer the
added benefits of having the air continuously cleaned year-round,
and humidified during the winter season.
• Your air conditioner will remove humidity from your home
during the cooling season. After a few minutes of operation, you
should be able to see water trickle from the condensate drain of the
cooling coil. Check this occasionally to be sure the drain system is
not clogged. Of course, don't expect to see much drainage if you
live in a very dry environment.
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your
home comfort system should be inspected regularly by a properly
trained service technician. The inspection (preferably each year,
but at least every other year) should include the following:
• Routine inspection of air filter(s). Replacement or cleaning as
required.
• Inspection and cleaning of the blower wheel, housing, and motor.
• Inspection and, if required, cleaning of indoor and outdoor coils.
• Inspection of the indoor coil drain pan, plus the primary and
secondary drain lines. If supplied, the auxiliary drain pan and line
should be inspected at this time. Service should include cleaning if
required.
• A check of all electrical wiring and connections.
• A check for secure physical connections of individual compo-
nents within units.
• Operational check of the air conditioning system to determine
actual working condition. Necessary repair and/or adjustment
should be performed at this time.
Your servicing dealer may offer an economical service contract
that covers seasonal inspections. Ask for further details.
