Never permit an automatic clothes drier to discharge its heat and moisture
inside an air conditioned house. It will place a load upon the cooling unit that
may cause discomfort for hours. Many complaints of unsatisfactory cooling
have been traced to this one cause. Driers must be vented to the outdoors.
When venting to the outdoors, never vent close to the outdoor portion of the
Heat Pump as you will quickly fill its coils with lint.
A hand iron or a mangle releases heat into the air, the difference between the
two, only being the amount of heat released. Ironing should be done on a
cool day or late in the evening when the cooling system has reserve capacity
and can remove this extra heat without noticeable difficulty.
Tub and shower baths release heat and moisture (steam) into the air. The
shower bath releases more than the tub bath, and of course, the longer the
shower the more released heat and moisture. A bathroom ventilating fan in
operation while the baths are being taken, will remove the heat and moisture.
Do not use a shower curtain that absorbs water – use one of plastic materials
or other non-absorbent materials.
Your Heat Pump will remove odors from the house that are dust-borne
because the dust will be eliminated by the filters and the wet surfaces of the
cooling coil. Incidentally, the water that drips off the cooling coil is not
equivalent to distilled water, since it is filled with dust, germs and dust-borne
odors.
Your Heat Pump was sized and designed to keep you and your family
comfortable. Unless you Dealer was told to provide cooling for an additional
15 or 20 people, your system will probably not keep this many people
comfortable on a hot day. Lowering the thermostat setting will not help.
Filters should be cleaned periodically. Dirty ones affect the operation of the
equipment by reducing the amount of air that can be moved through it.
Mold or mildew should not appear on clothing or household furnishing in air
conditioned houses. If it does appear, the indoor relative humidity is probably
too high and should be investigated. Most conditions of this kind can be
traced back to an undiscovered source of moisture within the house and to
where more moisture is entering the room air than the air conditioner can
remove. This source must be located and promptly eliminated. There are
many possible sources. The most common is moisture coming from the
following:
1. Through a concrete floor that is improperly protected from soil moisture.
2. Through the floor over a crawl space which does not have a moisture
barrier over the ground.
3. Through the floor over a damp basement.
It is recommended that the blower for air circulation be run continuously
during the operation. During mild weather when the unit does not operate for
long periods, this circulation in the air conditioned area will eliminate any
"muggy" feeling.
Windows on the east, south and west sides of the house that are not
protected from the sun on the outside, should be protected on the inside with
Venetian blinds or heavy draperies. Keep them closed or drawn when the
sun is on their side of the house. Inside protection against sun will not be as
effective as outside protection but it will help tremendously.
Windows should remain closed throughout the cooling season. To open
them lets in warm air and often highly humid air, particularly at night. Do not
open the doors more often than necessary and then for as short a period as
possible. It usually costs more to cool a house with children that are running
in and out at frequent intervals because each time the door is opened warm
air come in.
Your unit is thermostatically controlled and should be allowed to operate as
required throughout the cooling season. The thermostat will operate the unit
only as necessary to keep you comfortable and requires no help. There are
technical reasons why uninterrupted operation is the most satisfactory.
The physical thermal shock to the body of a person going out of or into an air
conditioned space, so often associated with cooling during hot weather, has
been no major problem with residential air conditioning. There appears to be
no dangerous physical shock to a normally healthy person entering or leaving
an air conditioned apace, although the change may be temporarily
unpleasant. This however, may not be the case with persons in ill health.
With such persons the greater the difference in temperature between the air
conditioned space and the outdoors, the greater the reaction or discomfort
will be. Mothers with small children who go in and out of doors frequently
have avoided the possibility of this by maintaining a slightly higher
temperature indoors.
You will learn that there are many more things that you Heat Pump will do for
you which we have not mentioned. Many of these you will recognize when
they present themselves. If you will remember to minimize the release of
heat and moisture indoors, especially on hot "muggy" days, you will realize
maximum comfort for your air conditioning system.
Folks who live in air conditioned homes generally eat better, stay at home
more, and are more amiable, along with countless other blessings that only
domestic air conditioning can bring.
THE HEAT PUMP HEATING CYCLE
There are certain preparations that must be made for the heating season.
The same as for the cooling season.
For instance, close the attic ventilators to keep out cold winds. Be sure that
storm windows indoors are in position to eliminate any drafts that might
occur.
All the family living habits that were curtailed during the cooling season, do
not have to be watched so closely in the heating season. On the contrary,
any activity that will give off heat or moisture will be beneficial as long as it
has no direct bearing on the thermostat.
To obtain the Heating Cycle, move the System Switch from "Cool" to "Heat".
Here again, the most desirable comfort seeing at the thermostat that is
satisfactory to you should be maintained throughout the heating season.
Turning the thermostat up and down at frequent intervals will give you
unsatisfactory operation, poor comfort conditions as well as unbalanced
conditions.
The operation of this portion of the thermostat is also automatic in that when
the temperature increase is desired, the Heat Pump will turn on
automatically. Here again, it is our recommendation that the fan switch be
allowed to operate in the ON position rather than cycle with heating
requirements. This will eliminate stratification of air; it will maintain a better
temperature gradient between floor and ceilings, and generally will make the
thermostat much more sensitive.
There are a number of points in the operation of the Heat Pump which do
differ considerably from other heating systems. While these points are not
necessarily bad, it is useful to understand how the system should operate for
your own peace of mind.
AIR DELIVERY . . . The air-volume requirement of a Heat Pump is
considerably more than that of a gas or oil fire heating system. The greater
air-volume is needed for maximum efficiency of operation. The fact that so
much air-volume is required leads to several important considerations. The
temperature of the air delivered is lower than with other systems. At some
time, the Heat Pump will be delivering air at a temperature just over 80
degrees. Even though this temperature is warm enough to heat your house,
it may feel cool to the touch. It is very important that the system be allowed
to move the full air-volume for which it is designed. This means that registers
should never be blocked with furniture or pictures. It means that the filters
must be kept clean so as not to restrict air delivery. It also means that you
should resist the impulse to close off registers, even in occupied rooms.
