YOUR COMFORT
SYSTEM
Identifying Your System
Take the 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.
IMPORTANT FA CTS
T o better protect your in vestment and to
eliminate unnecessary service calls,
familiarize yourself with the following
facts:
Listen To Your Unit
•
Your air conditioner has a scroll
compressor. Get to know the characteristic start-up and operational sounds.
Keep Filter Clean
•
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.
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, 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.
Get To Know Your
•
Thermostat
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 rapidcycling, 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.
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 pock ets
may be too cool or warm for your
Improper installation, adjustment, alteration, service, 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 assistance. The
qualified installer or agency
must use factory-authorized
kits or accessories when modifying this product.

OPERA TING Y OUR
AIR CONDITIONER
The operation of your air conditioning
system is controlled by the indoor
thermostat. Y ou simply adjust the
thermostat and it maintains the indoor
temperature at the level you select. Most
thermostats have three controls; a temperature control selector, a FAN control,
and a SYSTEM or MODE control.
Thermostats may vary from those sho wn
in Fig. 2 and 3.
The temperature control selector can
be a button, lev er , or set of buttons that
allows you to establish the degree of
temperature that 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 for setting the heating
operation temperature.
The F AN control offers two options for
controlling the blower; AUTO and ON.
When set to AUTO, the blower will run
only while the thermostat operates the
cooling or heating section. When the F AN
control is set to ON, the blower will run
continuously—regardless of whether the
cooling or heating section is operating.
T ypically, the SYSTEM or MODE control
on your thermostat offers the follo wing
selections; COOL, OFF , and HEAT. Your
thermostat may also have 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. With the SYSTEM or MODE control set to HEAT , the
heating section will operate automatically
when the indoor temperature falls below
the level that you ha v e selected.
The AUTO 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, or 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.
NOTE: For 2-speed air conditioners, this
special feature is built in to protect the unit.
• 1-MINUTE TIME DELAY – When
changing speeds from low to high, or
high to low, there is a 1-minute time
delay . During the speed change delay, the
outdoor fan will continue to run.
If you wish to program your accessory
electronic indoor thermostat, refer to
thermostat Installation Instructions.
COOLING CYCLE
When operating in the cooling cycle,
your air conditioner will run until the
indoor temperature is lowered to the le vel
you have selected. On e xtremely hot
days, your air 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.
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 ha ve 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.
NOTES: a) Two-speed air conditioners
operate for long periods of time on low
speed. This operation improv es system
efficiency and your comfort through closer control of temperature and humidity.
Expect longer operating cycles.
b) W ith tw o-speed air conditioners, low
and high indoor airflow settings are critical
for maintaining system comfort and efficiency. Consult your installer for airflow
setting adjustments.
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 case, 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.
Fig. 5—Removing Filter
from Fan Coil Unit
Disposable filters should be replaced by
similar, ne w filters of the same dimensions.
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. T o a v oid prolonged shutdown of your unit while a filter
is drying, you should have an e xtra filter
on hand. This would allo w you to switch
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 returnair duct or plenum. (See Fig. 5.)
Remove the filter cov er plate by sliding
latches toward center of plate. Lift filter
to clear lower flange. Filter is springloaded 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 application, the filter could
be located behind the return air grille.
Access the filter by removing 2 scre ws
from return air grille.
ELECTRONIC AIR CLEANER
If your system contains an Electronic Air
Cleaner consult the User’ s Manual for
specific care of that product.
INDOOR COIL
If the indoor 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. Howe ve r ,
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 thor ough 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 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/procedures for your
geographic area or service contract.
UNIT SUPPORT
Your split-system outdoor unit should be
maintained in 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
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor disconnect switches. Verify that circuit breakers are on or that fuses have not blo wn.
• 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 AUT O.
If you require warmth, be sure the temperature control selector is set above
room temperature and the SYSTEM or
MODE control is set to HEAT or A UT O.
The F AN should be set to ON for continuous blower operation or AUTO if you
wish blower to function only while the
unit is operating.
• Check note concerning special features
and time delays in “Operating Y our Air
Conditioner” section.
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 ha ve 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 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,
5
plus the primary and secondary drain lines.
