SAFETY CONSIDERATION

Recognize safety information. This is the safety-alert symbol
When you see this symbol on the unit or in instructions and man-
uals, be alert to the potential for personal injury.
Understand the signal word DANGER, WARNING, or CAU-
TION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result
in severe personal injury or death. WARNING signifies haz-
ards that could result in personal injury or death. CAUTION
is used to identify unsafe practices which would result in minor
personal injury or product and property damage.
WARNING
!
Improper installation, adjustment, alteration, ser-
vice, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause personal injury or property damage.
Consult a qualified installer, service agency, or
your distributor or branch for information or as-
sistance. The qualified installer or agency must
use factory-authorized kits or accessories when
modifying this product.

To prevent personal injury, death, or property
damage, read and follow all instructions and warn-
ings, including labels shipped with or attached to
the unit before operating your new air conditioner.
YOUR COMFORT SYSTEM
Identifying Your System
Take the time to familiarize yourself with the type of system you
have. This knowledge will be useful in understanding the basic
operation of your new air conditioner.
The split-system type has an indoor and an outdoor unit, each of
which contains a coil. These units are interconnected by refrig-
erant tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to it. A rating plate
. provides necessary information for specific identifica-
!
tion of a unit. You should familiarize yourself with the
product, model, and serial numbers listed on each rating plate.

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 properly installed clean air filter. Plan to inspect the filter peri-
odically. 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 effi-
ciency and shortens its life span.
• The outdoor unit must have unrestricted airflow. Do not cover
the unit, lean anything against it, or stand on it. Do not allow grass
clippings, leaves, or other debris to accumulate around or on top
of 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.
• 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 pock-
ets may be too cool or warm for your liking. Continuous fan oper-
ation 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 sys-
tem is not clogged. Do not expect to see much drainage if you live
in a very dry environment.
• Do not operate your unit when outdoor temperature is below
55°F.
