Fan Operation
Selection
A multi-position
fan switch allows you to choose the type of fan opera-
tion of the indoor fan.
AUTO - With the thermostat fan switch set to "AUTO", the fan will run
intermittently
as required for either heating or cooling. This position will
provide the lowest operating cost.
ON - If the fan switch is set to "ON", the indoor fan will not shut off. How-
ever, the system will still operate as required by room temperatures.
This provides continuous air filtering and more even temperature
distri-
bution throughout
the house, which is especially useful in houses with
basements.
Usually during
spring and fall, when neither
heating
nor cooling
is
required, you may want to run only the fan to ventilate, circulate, and fil-
ter the air in your home or building. Set the comfort control switch to
"OFF" and the fan switch to "ON". Be sure to return the switches to their
original positions for normal operation.

COOLING
YOUR
HOME:
With
the comfort
control
switch
in the
"COOL" position, the system will operate as follows: When the indoor
temperature
rises above the level indicated by the temperature
adjust-
ment setting, the system will start. The outdoor unit will operate and the
indoor fan will circulate cool, filtered air. When the room temperature
is
lowered to the setting selected, the system will shut off.
HEATING YOUR HOME: If your system includes a heating unit and the
comfort control switch is in the "HEAT" position, the system will operate
as follows:
When the indoor temperature
drops below the level indi-
cated by the temperature
adjustment
setting, the system will start. The
heating system will operate and the indoor fan will circulate warm, fil-
tered air. When the room temperature rises to the setting selected, the
system will shut off.
Whether
heating or cooling, the fan will continue to operate if the fan
switch was set in the "ON or Intelligent" position. The "AUTO" setting on
the fan switch will allow the fan to shut off when your system does.
ELECTRONIC
THERMOSTAT
The computerized
electronic thermostat,
when programmed,
will func-
tion automatically
to operate the system as follows: When the indoor
temperature
rises above the higher (COOL) setting, the outdoor unit will
operate and the indoor fan will circulate cool, filtered air. When the room
temperature
is lowered to the selected level, the system will shut off.
When the indoor temperature drops below the lower (HEAT) setting, the
heating system will operate, and the indoor fan will circulate the warm,
filtered air. When the indoor temperature
rises to the selected setting,
the system will shut off. The indoor fan will either shut off or run continu-
ously, depending upon your choice of fan switch setting.
TO MAXIMIZE
OPERATING
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.
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 mois-
ture 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 sys-
tem. 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 wails
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
condi-
tioned 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 periodic maintenance
unless they are experi-
enced and qualified to do so.
A periodic inspection,
cleaning, lubrication, and adjustment of your out-
door unit 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.
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 refrig-
erant 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
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
114 teaspoon)
of SAE 20 non-detergent
electric motor oil or automobile
oil. DO NOT
use definite purpose oils such as sewing machine, cleaning, rust pre-
ventative, cutting, household, etc.
