Any residential heating system is the reverse of
a cooling system. Family living habits that help
the heating system hurt the cooling system.
The heat pump, furnace, or boilerdelivers heat
into the rooms and the heat that is created
within the house from electric lights, cooking,
the TV set, etc. helps to heat the rooms -
therefore, that much less heat is required from
the b_lsr, furnace, or heat pump.
Cooling is just the reverse. The cooling equip-
ment removes heat and humidity. Any extra
heat released into the rooms from these same
sources will make the room air warmer and
place an extra burden upon the equipment.
Let's take the heat caused by cooking. For
example, four top burners of a gas range can
produce more heat than a three horsepower air
conditioner can remove. It is much more prac-
tical and economical to ventilate this concen-
trate heat and moisture load than it is to dispose
of it through your air conditioner. Here is a
general rule.
THERMOSTAT SETTING
For cooling, a temperature of 75 to 78 degrees
is preferred by most people. You may select
lower temperature setting if you wish and you
will probably have that temperature a good
portion of the time. But do not be disappointed
and condemn the equipment if the temperature
gets a few degrees war_e_during hot weather.
Set the thermostat at the temperature agree-
able to the family and leave it there.
Do not be concerned if, in the evening, when the
outside temperature drops below the inside
temperature, your air conditioning system is still
running. The entire structure of your house has
been soaking up heat from the sun all day long.
After the sun has set there is still a tremendous
amount of heat in the walls, ceiling, roof, fur-
nishings, etc., that must be disposed of before
the air conditioner stops running. Outdoor
temperatures can drop rapidly after sundown,
while the house and its furnishings continue to
give off heat for several hours.
Whenever you plan to have your oven or
range top burners on for more than a few
minutes during hot weather, close off the
kitchen from the rest of the house, open
a window or outside door, and turn on
your kitchen ventilator.
You can also effectively reduce the load on your
cooling system by keeping window shades,
blinds, or drapes closed or by installing awnings
or canopies.
There are days when the temperature is rela-
tively high, yet it is comfortable because the air
is dry. This is because the relative humidity is
low. There are other days when the tempera-
ture is about the same but there is discomfort.
This is because the humidity is high.
Indoors, the air should be both cool and rela-
tively dry for comfort. Therefore," the cooling
unit has been designed to remove both heat
and moisture.
Indoor Blower and Outdoor Fan Operation:
To improve the efficiency of the unit, the blower
is operated on a time delay. Depending on the
outside ambient, the blower could delay starting
up for 5 to 15 seconds even though the
thermostat calls for cooling or heating and when
the thermostat is satisfied, the blower could.
keep on running for 1/2 to I 1/2 minutes longer.
Do not be alarmed if you do not hear the blower
running immediately after the unit switches on.
When you unit is being automatically defrosted,
the outdoor fan will stop while the unit is still
running. Do not be concerned, this is a normal
operation. The fan will automatically restart
after the unit has completed its defrost cycle.
After a defrost cycle, you may find condensate
dripping from the unit on to the pad or roof. This
is normal.
Your unitis a Heat Pump. It is producing heated"
air on the heating cycle and cooled air on the
cooling cycle. The cooling or heating is
accomplished by means of remote controls, is
completelyautomatic, and requires noattention
after setting to the comfort level you desire.
