On your purchase of one of the most versatile comfort conditioning systems available in the industry today. This high efficiency system has been precision designed, manufactured of high quality materials and has passed many vigorous inspections
and tests to ensure years of satisfactory service.
This booklet is meant to increase your understanding of your system, tell you how to operate it efficiently and how to obtain
the greatest measure of comfort at the lowest operating expense. Please read this booklet thoroughly.
We appreciate your interest in our product and your decision to purchase our system. Enjoy your comfort.
This high efficiency air conditioning
system has been precision engineered, manufactured of high quality
materials, and has been passed many
rigorous tests and inspections to
ensure years of satisfactory service.
That's why you can rely on efficient,
trouble-free operation.
Your system is fully automatic. Set the
thermostat and forget it. And it's automatically protected from damage by
voltage fluctuations or excessive heating or cooling demands.
Your split system air conditioner consists of two units - one installed outdoors and one installed indoors. The
indoor unit may be installed in a basement, attic, or crawl space.
HOW YOUR AIR
CONDITIONER WORKS
If your hand is wet and you blow on it,
it feels cool because some of the moisture is evaporating and becoming a
vapor. This process requires heat. The
heat is being taken from your hand, so
your hand feels cool.
That's what happens with an air conditioner. During the cooling cycle, your
system will remove heat and humidity
from your home and will transfer this
heat to the outdoor air.
SYSTEM OPERATION
Your thermostat puts full control of the
comfort level in your home at your fingertips.
DO NOT switch your thermostat rapidly “On" and “Off" or between “Heat"
to “Cool" This could damage your
equipment. Always allow at least 5
minutes between changes.

SETTING THE THERMOSTAT
System Off - On stand by: No heating,
cooling, or blower air. Set system
switch to “Off" and fan switch to “Auto".
Fan Only - On moderate days, usually
during spring and fall, when neither
heating nor cooling is required, you
may want to run only the fan to ventilate, circulate and filter the air in your
home or building. Set the system
switch to “OFF” and the fan switch to
“ON”. Be sure to return the switches to
their original positions for normal operation.
Cooling - To operate the air conditioner, set system switch to “Cool", fan
switch to “Auto", and the temperature
selector lever to the desired temperature. For a cooler temperature, set
lever to lower number. For less cooling, set lever to higher number.
Heating - To operate the furnace for
heat, set system switch to “Heat", fan
switch to “Auto", and the temperature
selector lever to the desired temperature. For a higher temperature, set
lever to higher number. For a lower
temperature, set the lever to a lower
number.
Continuous Air Circulation - Regardless of whether heating or cooling the
home: Set fan switch to “On", system
switch to either “Heat" or “Cool" and
the temperature selector lever to the
desired temperature. This provides
continuous air filtering and more even
temperature distribution to all conditioned spaces. The sound level within
the home/building will also remain relatively constant.
To operate a Programmable/Electronic
thermostat: Refer to its User's Manual.
Set your thermostat for heating or for
cooling. Then set it for the desired temperature. Find the temperature that is
most comfortable for you, and then
leave your thermostat alone. Manually moving the thermostat up or
down to extreme settings will not
speedup
temperature
changes.
Avoid moving the thermostat up during heating - particularly where a
demand type electric meter is installed
and electric furnace is installed for
heating. This will increase your operating cost substantially.
The main power to the system must be kept “ON" at all
times to prevent damage to
the outdoor unit compressor.
If necessary, the thermostat
control switch should be used
to turn the system “OFF".
Should the main power be
disconnected or interrupted
for 8 hours or longer, DO
NOT attempt to start the system for 8 hours after the
power has been restored to
the outdoor unit. If heat is
needed during this 8 hour
period, use emergency heat.

COOLING CYCLE
Switch your thermostat to cool. Select
a comfortable thermostat temperature
setting, typically between 75 and 80°.
Comfort sensations vary with individuals. The lower the indoor temperature
desired, the greater will be the number
of hours your unit must operate.
Set your thermostat 2 or 3°F below
normal several hours before entertaining large groups during hot weather.
People give off considerable heat and
moisture.
On an extremely hot day, the indoor
temperature may rise 3 to 6°F above
the thermostat setting. Properly
selected equipment does not have the
capacity to maintain a constant indoor
temperature during the peak load.
Over-sizing your system to handle this
peak load isn't practical because the
oversized system would operate much
less efficiently at all other conditions.

EFFICIENCY
HEATING CONSERVATION
For the most efficient operation, keep
storm windows and doors closed all
year long. They not only help insulate
against heat and cold, but they also
keep out dirt, pollen and noise.
Closing drapes at night, keeping fireplace dampers closed when not in use,
and running exhaust fans only when
necessary will help you to retain the air
you have already paid to heat.
Unitary Products Group
Keep lamps, televisions, or other heat
producing sources away from the thermostat. The thermostat will sense this
extra heat and will not be able to maintain the inside temperature to the
desired comfort level.
COOLING CONSERVATION
To comfortably cool your home, your
air conditioner must remove both heat
and humidity. Don't turn your system
off even though you will be away all
day. On a hot day, your system may
have to operate between 8 to 12 hours
to reduce the temperature in your
home to a normal comfort level.
Keep windows closed after sundown.
While the outdoor temperature at night
may be lower than indoors, the air is
generally loaded with moisture which is
soaked up by furniture, carpets, and
fabrics. This moisture must be
removed when you restart your system.
The hotter the outside temperature, the
greater the load on your system.
Therefore do not be alarmed when
your system continues to run after the
sun has set on a hot day. Heat is
stored in your outside walls during the
day and will continue to flow into your
home for several hours after sunset.
Use your kitchen exhaust fan when
cooking. One surface burner on
"HIGH" requires one ton of cooling.
Turn on your bathroom exhaust fan
while showering to remove humidity.
However, exhaust fans should not be
run excessively. It would decrease efficiency by removing conditioned air.
You can also help your system in the
summer by closing drapes or blinds
and by lowering awnings on windows
that get direct sunlight.
CARE OF SYSTEM
IMPORTANT: The Owner/user
should not attempt to disassemble
the equipment nor perform the
periodic maintenance unless he or
she is experienced and qualified to
Turn off the electrical power
at the main disconnect for
both the indoor heating unit
and the outdoor unit before
attempting any maintenance
operations.
A periodic inspection, cleaning, lubrication and adjustment of your air conditioning system is available from your
dealer. Be sure to ask him about this
service.
For those who prefer to do-it-yourself,
follow the instructions below to care for
your system.
Document and retain in your records,
the following information:

_______________________________
This information will be useful if the
unit requires service from a qualified
technician.
COIL CARE
Keep the outdoor unit free of loose
snow, foliage, grass clippings, leaves,
paper, and any other material which
could restrict the proper air flow in and
out of the unit. The coil may be vacuumed to remove any debris from
between the fins. However, don't knock
ice off the outdoor unit's coil surface
following an ice or severe snowstorm.
The blows could mash the coil fins
shut (blocking air passage), or break
the refrigerant tubing allowing the
refrigerant to escape.
If the coil becomes excessively dirty,
turn the main disconnect switch to
"OFF" and wash the coil with your garden hose. Avoid getting water into the
fan motor and control box. Flush dirt
from base pan after cleaning the coil.

CARE OF FAN MOTORS
Table 1: Schedule For Re-lubrication
Some fan motors are provided with
lubrication ports. Inspect your indoor
and outdoor units to determine
whether or not lubrication ports are
provided.
The fan motor is shipped with an oil
supply which will last for several years
under normal operating conditions.
After this time, each motor bearing
should be oiled with 10-15 drops
(approximately 1/4 teaspoon) of SAE
20 non-detergent electric motor oil or
automobile oil. DO NOT use definite
purpose oils such as sewing machine,
cleaning, rust preventative, cutting,
household, etc.

FILTER CARE
Inspect the air filter(s) at least once a
month. If they are dirty, wash reusable
filters with a mild detergent per manufacturer's recommendations. Replace
disposable filters with new filters.
Install the clean filters with air flow"
arrow in the same direction as the air
flow in your duct. Filters should be
clean to assure maximum efficiency
and adequate air circulation. Drapes,
furniture or other obstructions blocking
your supply and return air grilles will
also decrease efficiency.
OUTDOOR UNIT FINISH
If you wish to maintain the finish of the
outdoor unit, it can be polished with car
wax. It is recommended the unit be
cleaned with soap and water prior to
waxing.
