Keep lamps, televisions, or other heat  
producing sources away from the ther-  
mostat. The thermostat will sense this  
extra heat and will not be able to main-  
tain the inside temperature to the  
desired comfort level.  
COOLING CYCLE  
Switch your thermostat to cool. Select  
a comfortable thermostat temperature  
setting, typically between 75 and 80°.  
Comfort sensations vary with individu-  
als. The lower the indoor temperature  
desired, the greater will be the number  
of hours your unit must operate.  
Turn off the electrical power  
at the main disconnect for  
both the indoor heating unit  
and the outdoor unit before  
attempting any maintenance  
operations.  
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.  
Set your thermostat 2 or 3°F below  
normal several hours before entertain-  
ing large groups during hot weather.  
People give off considerable heat and  
moisture.  
A periodic inspection, cleaning, lubrica-  
tion and adjustment of your air condi-  
tioning system is available from your  
dealer. Be sure to ask him about this  
service.  
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.  
For those who prefer to do-it-yourself,  
follow the instructions below to care for  
your system.  
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 sys-  
tem.  
Document and retain in your records,  
the following information:

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.

COIL CARE  
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 effi-  
ciency by removing conditioned air.  
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 vacu-  
umed 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.

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.  
You can also help your system in the  
summer by closing drapes or blinds  
and by lowering awnings on windows  
that get direct sunlight.  
Closing drapes at night, keeping fire-  
place 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.  
CARE OF SYSTEM  
If the coil becomes excessively dirty,  
turn the main disconnect switch to  
"OFF" and wash the coil with your gar-  
den hose. Avoid getting water into the  
fan motor and control box. Flush dirt  
from base pan after cleaning the coil.  
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

Table 1: Schedule For Re-lubrication  
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.  
CARE OF FAN MOTORS  
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.

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.  
NOTE: DO NOT OVER OIL  
FILTER CARE  
Inspect the air filter(s) at least once a  
month. If they are dirty, wash reusable  
filters with a mild detergent per manu-  
facturer's recommendations. Replace  
disposable filters with new filters.

PARTS INFORMATION  
The minimum clearances shown below  
must be maintained should any patio  
or yard improvements be done around  
the outdoor unit.  
There are a few instances where you  
can avoid unnecessary service calls.  
(See Troubleshooting Guide above).  
Some models provide fault codes. The  
flashing light on the system thermostat  
is capable of providing you with time  
and money saving information. The  
fault code numbers listed can be han-
