NOTE TO INSTALLER: This manual should be left with the
equipment owner.
Do not store or use gasoline or other flammable vapors and liquids
in the vicinity of this or any other appliance.
Failure to follow this warning could result in personal
injury, death or property damage.
Do not use this unit if any part has been under water.
Immediately call a qualified service technician to inspect
the unit and to replace any part of the control system
which has been under water.
A. Identifying Your System
Take the time to familiarize yourself with your packaged air
conditioning system. This knowledge will be of use in understanding the basic operation of your new air conditioner. The 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 in the space provided at the
end of this booklet.
To better protect your investment and to eliminate unnecessary
calls, familiarize yourself with the following facts:
1. 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.
Failure to follow this warning could result in personal
injury, death.
Before performing recommended maintenance, be sure
the main power switch to unit is turned off.
2. 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.
3. 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 on top of the unit. Maintain a 30-in.
minimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
4. Your multipurpose indoor thermostat is the control center
for your heat pump 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
(See Fig. 3).
5. 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. air pockets may be too cool or warm for your
liking. Continuous fan operation minimizes any temperature differences. Also, systems equipped with electronic or
mechanical air cleaners and/or humidifiers offer the added
benefits of having the air continuously cleaned year-round
and humidified during the winter season.
6. 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. 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.
The following are typical conditions that add extra heat and/or
humidity to your home. Your air conditioner will work longer to
keep your home comfortable under these conditions:
1. Entrance doors are frequently opened and closed
2. Laundry appliances are being operated
3. A shower is running
4. More than the usual number of people are present in the
5. More than the normal number of electric lights are in use
6. Drapes are open on the sunny side of the home

B. Heating Cycle
If you own a packaged air conditioner that includes electric heat as
an accessory, you need to set your thermostat for heating when it
is desired.
With the SYSTEM switch of your indoor thermostat set to the
HEAT position, 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 colder days and
nights than on moderate ones.
Failure to follow this warning could result in personal
injury, death and/or property damage.
To prevent serious injury, death, or property damage,
read and follow all instructions and warnings, including
labels shipped with or attached to unit before operating
your new heat pump.
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 for air conditioning systems have 3 controls: a
temperature control selector, a FAN control, and a SYSTEM or
MODE control.
A. Cooling Mode
When operating in cooling mode, your air conditioner will run in
cooling mode 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.

With the proper maintenance and care, your air conditioner will
operate economically and dependably. Maintenance can be accomplished easily by referring to the following directions. However,
before performing maintenance, consider these important safety
Your packaged air conditioning 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 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.
Failure to follow this warning could result in personal
injury and/or death.
Disconnect all electrical power to the indoor air handler
or furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and
outdoor units. Note: There may be more than 1 electrical
disconnect switch.
1. Check the indoor and outdoor disconnect switches. Verify
that circuit breakers are ON or that fuses have not blown.
Failure to follow this caution may result in personal
Although special care has been taken to minimize sharp
edges in the construction of your unit, to avoid injury be
extremely careful when handling parts or reaching into
the unit.
2. 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.
3. Check the settings on your indoor thermostat. If you desire
cooling, make sure 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,
make sure that the temperature control selector is set above
room temperature and the SYSTEM or MODE control is set
to HEAT or AUTO. The FAN control should be set to ON
for continuous blower operation or AUTO if you wish
blower to function only while your air conditioner is
operating. If your comfort system still fails to operate, turn
your system off and contact your servicing dealer for
troubleshooting and repairs. Specify your apparent problem, and state the model and serial number of your
equipment. (You should have them recorded on the last
page of this booklet.) With this information, your dealer
may be able to offer helpful suggestions over the phone or
save valuable time through knowledgeable preparation for
the service call.
A. 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 worst 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
MONTHS. 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.
Reusable, permanent filters should be washed in a solution of cold
water and mild detergent, then rinsed and thoroughly dried. THE
REINSTALLED. To avoid prolonged shutdown of your unit while
a filter is drying, you should have an extra filter on hand. This
allows you to rotate between the two with minimal downtime for
your comfort system. Extra filters may be purchased from your
The filters(s) and filter rack for a packaged system are supplied
and installed by the contractor or dealer. Typically, the filter(s) and
rack are located in the return-air duct at the outdoor unit or behind
the return-air grille(s). Have your dealer show you the location of
your filter(s) and the procedures for removal and replacement.
If your system includes a high efficiency or electronic air cleaner,
refer to air cleaner User’s Manual for proper filter cleaning or
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 twice each
year, but at least once every year) should include the following:
1. Routine inspection of air filter(s). Replacement or cleaning
as required.
2. Inspection and cleaning of the blower wheel, housing, and
motor as required.
3. Inspection and, if required, cleaning of coils.
4. A check of all electrical wiring and connections.
B. Outdoor Coil
If grass clippings, leaves, shrubbery, and debris are kept away
from the unit, minimal care should be sufficient to keep the system
functioning properly. However, if the outdoor coil becomes dirty,
use a vacuum cleaner or shop vac with soft brush attachment to
clean the exterior surface. Vacuum coil surface using an up and
down motion. Be careful not to bend or damage fins.
5. A check for secure physical connections of individual
components within unit.
6. Operational check of the air conditioning system to determine actual working condition. Necessary repair and/or
adjustment should be performed at this time.
7. Your servicing dealer may offer an economical service
contract that covers seasonal inspections. Ask for further
If dirt is deep in the coil, contact your dealer for service. Do not
attempt this yourself.
C. Outdoor Coil—Sea Coast
If your unit is located near the ocean, special maintenance is
required. Ocean mist/breeze carries salt, which is corrosive 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, you will be
adding additional life to your unit. Please consult your installing
contractor for proper intervals/procedures for your geographic area
or service contact.
You have purchased a 564B series unit. Be sure to read the
warranty at the back of this booklet carefully to determine the
coverage for your unit.
Record the model, product, and serial numbers of your new
equipment in the spaces provided. This information, along with the
other ready-reference facts requested will be necessary should you
ever require information or service.
