YOUR COMFORT
SYSTEM
Identifying Your System
Take time to get to know the type of
system you have. This will be helpful 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
refrigerant tubes. (See Fig. 1.)
Each unit has a rating plate affixed to it
which provides necessary information
for specific identification of a unit. You
should familiarize yourself with the
product, model, and serial numbers listed
on each rating plate. Record them for
future reference on last page of this
booklet.
IMPORTANT FACTS
To better protect your investment and to
eliminate unnecessary service calls,
familiarize yourself with the following
facts:
Keep Filter Clean
•
Y our air conditioning system should nev er
be operated without a properly installed,
clean air filter . Plan to inspect the fi lter
periodically . A clogged air filter will
increase operating costs and shorten the
life of the unit.
Do Not Block Registers
•
Supply-air and return-air registers should
not be blocked. Drapes, furniture, and
toys are some of the items commonly
found obstructing registers. Restricted
airflow lessens the unit’s efficiency and
life span.
Do Not Cover or Block
•
Outdoor Unit
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, leav es, 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.
Get To Know Your
•
Thermostat
Your multipurpose indoor thermostat is
the control center for your air conditioning system. Y ou should f amiliarize
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 rapidcycling, which is potentially damaging
to the compressor . Do not mo v e the
temperature selector on the thermostat for
any reason for at least 5 minutes after the
compressor has shut off.
Continuous Fan
•
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 your
liking. Continuous fan operation
minimizes temperature differences.

Humidifiers
Systems equipped with electronic or
mechanical air cleaners and/or humidifiers offer the added benefits of ha ving the
air continuously cleaned year-round, and
humidified during the winter season.
Ventilation
•
A system equipped with a heat or
energy recovery v entilator offers the
advantage of exhausting stale air from the
home and allowing fresh air in from the
outdoors while minimizing heat loss.

Y our system may also be equipped with a
zoning system which allows indi vidual
control over the temperatures of separate
areas of your home.
Check Condensate Drain
•
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,

the level you select. Most thermostats
have three controls: a temperature control
selector, a FAN control, and a SYSTEM
or MODE control.
The temperature control selector can be a
dial, lever, or set of buttons that allows
you to establish the degree of temperature
you wish to maintain for your personal
comfort. Some thermostats possess
two temperature control selectors: one for
setting the temperature desired during the
cooling cycle, and one to set the heating
operation temperature.
The FAN control offers two options for
controlling the indoor blower: AUT O and
ON. When set to A UT O, the blo wer runs
only while the thermostat operates the
cooling or heating section. When set to
ON, the blower runs continuously—
regardless of whether the cooling or
heating section is operating.
Typically, the SYSTEM or MODE control on your thermostat offers the following selections: COOL, OFF, and
HEA T. Your thermostat may also ha ve a
fourth selection, AUTO. Neither the
cooling or heating section will operate
when the SYSTEM or MODE control is
set to OFF. With the SYSTEM or
MODE control set to COOL, the cooling section of your comfort system will
operate when the indoor temperature
rises above the level that you wish to
maintain. W ith the SYSTEM or MODE
control set to HEAT , the heating section
will operate automatically when the
indoor temperature falls below the le vel
that you have selected.
The A UT O selection found on some thermostats provides for automatic
changeover between cooling and heating
cycles. With the SYSTEM or MODE
control set to A UT O, the cooling section
will operate when the indoor temperature
rises above the thermostat cooling temperature setting, and the heating section
will operate when the indoor temperature
drops below the thermostat setting for the
heating cycle.
Your thermostat may be PROGRAMMABLE or NON-PROGRAMMABLE.
A NON-PROGRAMMABLE thermostat does not allow the temperature settings to be varied throughout the day or
week without physically changing the
settings. A PR OGRAMMABLE thermostat allows various daily temperature
changes to be preset. During the winter ,
for example, you may wish to set back
the temperature of your home at night,
then have the temperature return to
normal prior to waking up. The home’s
temperature can then be lowered again
during the day when no one is at home,
but again be at peak comfort level when
your family returns home. During the
summer, the opposite changes might be
programmed. When properly used, the
programming can result in energy savings on your home’ s heating and cooling.
COOLING CYCLE
When operating in the cooling cycle,
your air conditioner runs until the indoor
temperature is lowered to the level you
have selected. On extremely hot days,
your conditioner will run for
longer periods at a time and have
shorter off periods than on moderate
days.
The following are typical conditions
that add extra heat and/or humidity to
your home and force your cooling unit
to work longer to keep your home
comfortable:
• Entrance doors are frequently opened
and closed
• Laundry appliances are being operated
• A shower is running
• More than the usual number of people
are present in the home
• More than the normal number of electric lights are in use
• Drapes are open on the sunny side of
the home

from Fan Coil Unit
HEATING CYCLE
With the SYSTEM or MODE control of
your indoor thermostat set to HEAT, the
heating section of your home comfort
system will operate until room temperature is raised to the level you have
selected. Of course, the heating unit will
have to operate for longer periods to maintain a comfortable environment on cooler
days and nights than on moderate ones.
Refer to your furnace User’s Manual
for specific information on heating
operation.
PERFORMING ROUTINE
MAINTENANCE
With the proper maintenance and care,
your air conditioning unit will operate
economically and dependably. Maintenance can be accomplished easily by
referring to the following directions.
Howev e r, before performing maintenance, consider these important safety
precautions:
!
WARNING
To prevent personal injury, or
death, disconnect all electrical
power to the air conditioner before removing access panels or
performing any maintenance.
Disconnect power to both the
indoor and outdoor units. Note:
There may be more than 1 electrical disconnect switch.
CAUTION
!
Although special care has been
taken to minimize sharp edges
in the construction of your unit,
be extremely careful when handling parts or reaching into the
unit.
CHECK THE AIR FIL TER
A dirty air filter will cause excessi ve
strain on the compressor and blower
motor. This can cause the components to
overheat and automatically shut do wn. In
the extreme, the components will fail and
need to be replaced. To avoid inefficient
or failed operation of your unit, CHECK
THE FILTER(S) EVERY 3 TO 4
WEEKS. Replace filter(s) when necessary , or clean the filter(s) if you have the
reusable type.
Disposable filters should be replaced
by similar, new filters of the same
dimensions.
Page 5
5
Reusable, permanent filters should be
washed in a solution of cold water
and mild detergent, then rinsed and
thoroughly dried. THE FILTER MUST
BE COMPLETELY DRY BEFORE
BEING REINSTALLED. To avoid
prolonged shutdown of your unit while a
filter is drying, you should have an e xtra
filter on hand. This would allow you to
rotate between the two with minimal
downtime for your comfort system. Extra
filters may be purchased from your
dealer.
There are no filters in the outdoor unit
of a split-system. If your indoor unit is a
gas or oil furnace, refer to your furnace
User’s Manual for fi lter location and
procedures for replacement or cleaning.
If your system includes an indoor fan coil
unit, the filter may be located in the unit
where it connects with the return-air duct
or plenum. (See Fig. 5.) Remove the filter
cover plate by sliding latches toward
center of plate. Lift filter to clear lower
flange. Filter is spring-loaded and will
pop out. Reinstall filter, being certain to
secure filter behind lower flange. When
reinstalling cover plate, secure plate
behind upper flange then slide tabs
outward.
The indoor fan coil unit may be located
in the attic. In this instance the filter could
be located behind the return air grille.
Access the filter by removing two scre ws
from return air grille.
INDOOR COIL
If the split-system coil has only been
operated with a clean filter in place, it
should require minimal cleaning.
If coil cleaning is required, call your
dealer for service. It may be necessary to
clean the coil with a detergent solution
and rinse it with water . This could require
the removal of the coil. You should not
attempt this yourself.
OUTDOOR COIL
If grass clippings, leaves, shrubbery , and
debris are kept away from the outdoor
unit, minimal care should be sufficient
to keep the system functioning properly .
For proper drainage, debris must be
removed periodically from the base pan.
However, if the outdoor coil becomes
dirty, use a vacuum cleaner with soft
brush attachment to clean the exterior
surface. V acuum coil surface using an up
and down motion. Be careful not to bend
or damage coil fins.
If dirt is deep in the coil, contact your
dealer for service. The outdoor fan
motor may have to be disconnected and
the top panel removed to gain access to
the coil for thorough cleaning. Do not
attempt this yourself.
OUTDOOR COIL—
SEA COAST
If your unit is located near the ocean, special maintenance is required. Ocean mist/
breeze carries salt, which is corrosiv e to
most metals. Although your new unit is
made out of galvanized metal and is
protected by top-grade paint, you should
take the precaution of additional maintenance which consists of periodically
washing the unit. By washing all exposed
surfaces and coil approximately every
3 months, you will be adding additional
life to your unit. Consult your installing
contractor for proper intervals and/or
procedures for your geographic area or
service contact.
UNIT SUPPORT
Y our split-system outdoor unit should be
maintained at a level position. If its
support should shift or settle so that the
unit is no longer level, you should correct
the condition. Relevel it promptly to
assure that water drains out of the unit. If
you notice that water or ice collects
beneath the unit, arrange for it to be
drained away from the unit.
BEFORE YOU REQUEST
A SER VICE CALL
BEFORE Y OU CALL FOR
SER VICE, CHECK FOR
THESE EASILY SOL VED
PROBLEMS:
• Check the indoor and outdoor disconnect switches. Verify that circuit break ers
are ON or that fuses have not blown.
• Check for sufficient airflo w. Check
the air filter(s) for any accumulations of
dirt. Check for blocked return-air or supply-air registers. Be sure registers are
open and unobstructed.
• Check the settings on your indoor thermostat. If you desire cooling, see that the
temperature control selector is set below
room temperature and the SYSTEM or
MODE control is set to COOL or
AUTO. If you require warmth, be sure
the temperature control selector is set
above room temperature and the SYSTEM or MODE control is set to HEA T or
AUT O. The F AN control should be set to
ON for continuous blower operation or
AUTO if you wish blower to function
only while the unit is operating.
If your comfort system still fails to
operate, contact your servicing dealer
for troubleshooting and repairs. Specify
your apparent problem, and state the
model and serial numbers of your equipment. (Y ou should have them recorded on
the last page of this booklet.) With this
information, your dealer may be able to
offer helpful suggestions ov er the phone
or save v aluable time through knowledgeable preparation for the service call.
REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance that
you perform, your home comfort system
should be inspected regularly by a trained
service technician. The inspection (prefer ably each year, b ut 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 components 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.
