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.

Your thermostat may be PROGRAM-
MABLE or NON-PROGRAMMABLE.
A NON-PROGRAMMABLE thermo-
stat does not allow the temperature set-
tings to be varied throughout the day or
week without physically changing the
settings.A PROGRAMMABLE thermo-
stat 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 sav-
ings on your home’s heating and cooling.
than 55°F without modification. If oper-
ation below this temperature is required,
consult your installer.
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 improves system
efficiency and your comfort through clos-
er control of temperature and humidity.
Expect longer operating cycles.
OPERATING YOUR
AIR CONDITIONER
The operation of your air conditioning
system is controlled by the indoor
thermostat. You simply adjust the
thermostat and it maintains the indoor
temperature at the level you select. Most
thermostats have three controls; a tem-
perature control selector, a FAN control,
and a SYSTEM or MODE control.
Thermostats may vary from those shown
in Fig. 2 and 3.
b) With two-speed air conditioners, low
andhighindoorairflowsettingsarecritical
for maintaining system comfort and effi-
ciency. Consult your installer for airflow
setting adjustments.
PERFORMING ROUTINE
MAINTENANCE
The temperature control selector can
be a button, lever, 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.
With the proper maintenance and care,
your air conditioning unit will operate
economically and dependably. Mainte-
nance can be accomplished easily by
referring to the following directions.
However, before performing mainte-
nance, consider these important safety
precautions:
NOTE: For 2-speed air conditioners, this
specialfeatureisbuiltintoprotecttheunit.
• 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.
The FAN 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 FAN
control is set to ON, the blower will run
continuously—regardless of whether the
cooling or heating section is operating.
!
WARNING
To prevent personal injury or
death disconnect all electrical
power to the air conditioner be-
fore removing access panels or
performing any maintenance.
Disconnect power to both the
indoor and outdoor units. Note:
There may be more than 1 elec-
trical disconnect switch.
COOLING CYCLE
When operating in the cooling cycle,
your air conditioner will run until the
indoor temperature is lowered to the level
you have selected. On extremely hot
days, your air conditioner will run for
longer periods at a time and have shorter
off periods than on moderate days.
Typically,theSYSTEMorMODEcontrol
on your thermostat offers the following
selections; COOL, OFF, and HEAT.Your
thermostat may also have a fourth selec-
tion, AUTO. Neither the cooling or heat-
ing 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 SYS-
TEM or MODE control set to HEAT, the
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:

CAUTION
Although special care has
been taken to minimize sharp
edges in the construction of
your unit, be extremely careful
when handling parts or reach-
ing into the unit.
• Entrance doors are frequently opened
and closed.
• Laundry appliances are being operated.
• A shower is running.

you notice that water or ice collects
beneath the unit, arrange for it to be
drained away from the unit.
CHECK THE AIR FILTER
A dirty air filter will cause excessive
strain on the compressor and blower
motor. This can cause the components to
overheat and automatically shut down. 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.
ELECTRONIC AIR CLEANER
BEFORE YOU REQUEST
A SERVICE CALL
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor dis-
connect switches. Verify that circuit break-
ers are on or that fuses have not blown.
If your system contains an ElectronicAir
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.
• Check for sufficient airflow. 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.
Ifcoilcleaningisrequired, callyourdealer
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.
• Check the settings on your indoor ther-
mostat. 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 orAUTO.
If you require warmth, be sure the tem-
perature control selector is set above
room temperature and the SYSTEM or
MODE control is set to HEAT orAUTO.
The FAN should be set to ON for contin-
uous blower operation or AUTO if you
wish blower to function only while the
unit is operating.
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 attach-
menttocleantheexteriorsurface.Vacuum
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 deal-
er 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

from Fan Coil Unit
Disposable filters should be replaced by
similar, new filters of the same dimensions.
• Check note concerning special features
and time delays in “OperatingYour Air
Conditioner” section.
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 pro-
longedshutdownofyourunitwhileafilter
is drying, you should have an extra filter
on hand. This would allow you to switch
between the two with minimal downtime
for your comfort system. Extra filters may
be purchased from your dealer.
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 equip-
ment. (You should have them recorded on
the last page of this booklet.) With this
information, your dealer may be able to

yourself.
OUTDOOR COIL—
SEA COAST
If your unit is located near the ocean, spe-
cial maintenance is required. Ocean mist/
breeze carries salt, which is corrosive 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
whichconsistsofperiodicallywashingthe
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.
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 filter location and
procedures for replacement or cleaning.
REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance
that you perform, your home comfort
system should be inspected regularly by
aproperlytrainedservicetechnician.The
inspection (preferably each year, but at
least every other year) should include the
following:
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.
• Routine inspection of air filter(s).
Replacement or cleaning as required.
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
