Please take a few minutes to read ourinstructions before you installand use your air conditioner. This
will help you obtain the full value from your air conditioner. It will also help you avoid any needless
service costs that result from causes we cannot control and cannot cover in our guarantee.
RULES
FOR INSTALLATION
1. Readthese rules andthe instructionscarefully. Failure to follow the rules and the
instructions could cause a malfunction of
the air conditioning unit resulting in injury,
4. Refer to Section VIII for maintenance procedures.
5. Do notoperate this unitat outdoortemperatures below 60°F on cooling.
6. The components of an air conditioner may
death and/or property damage.
2. Check your local codes and utility standards. The installation must comply with
their rules.
o
AND SAFE OPERATION
have sharp edges or protrusions which can
cut you. The tubing and compressor contain high pressure refrigerant. They must
not be exposed to high temperature or be
punctured. When installing or servicingthe
air conditioner, be extremely careful to
avoid injury.
Shut off the electric power before making
connections on the unit or removing panels
for servicing. (There may be morethan one
disconnect).
The importance of proper installationcannot be overemphasized. The best designed unitwill appear
to operate poorly if installed improperly. Unlike the small appliance where quality of operation can
usually be determined as it leaves the factory, the performance of an air conditioner depends, to a
large extent, on its installation.
Problems always occur if the installer does not take precautions in the following areas:
Wire Size
- Inadequate wire sizes can cause an excessive voltage drop, causing the
compressor and fan motors to operate at undesirably low voltage rates.
Duct Size
- Inadequate duct size, elbows, distributorsor registers can restrict air flow.
Duct Openings
- Improperly sealed duct sections can cause considerable
capacity due to air leakages.
Duct Insulation
- Inadequate duct insulation in attic space will cause heat gain in the system.
Refrigerant Gharge
- Unit is precharged, but should a change be necessary, it should be verified
against the operating system pressures, temperatures, and current draws as
specified in the catalog.
loss in cooling
These air conditioners have proven their reliability over several decades. Years of research,
engineering and only the highestquality component parts and workmanshiphave gone intothese units
to make them the most reliable in the industry. Before a model is released for production,it undergoes
a battery of tests in environmentaltest rooms with conditions of up to 120°F desert temperatures.

It is very important that the ducts for a selfcontained system be properly sized, installed,
sealed, and insulated for the best performance
of the system. It is recommended that boththe
supply and the return duct be insulated (2")

when installed inan unconditionedarea. Where
the supply duct is exposed to the outdoor
temperatures, vapor barrier material should be
used. All duct work should be installed in
accordance with ASHRAE or NAHB.

This system is a completely self-contained
cooling unitwith all components in one cabinet.
It isshipped completely charged withthe proper
amount of refrigerant. The unit is ready for
operation after connecting duct work, condensate drain and power supply. An adhesive
backed soft-foam weather strip or caulking
must be attached on the horizontal channel
between the supply and retum air openings as
shown on page 5. A condensate "p"trap must
be installed for every unit as shown also on
page 5.
INSTALLATION

mounts are to help eliminate vibration and
noise. Ground installationisbasicallythe same
for both self-contained units and split-system
outdoor units. Locate the unit on a concrete
slab or blocks not connected to the buildings

diameter and be properly graded.
The actual amount of total refrigerant charge
for each installation may have to be adjusted to
insure that unit performance characteristics
(compressor electrical current draw, suction
and discharge pressures) are consistent with
those given in the application tables for the
applicable ambient conditions.

are complete, a temperature difference of
15 ° to 20 ° is considered satisfactory.
If power to unit has been disconnected for
any extended period of time, restore power
twelve (12) hours prior to start-up procedure.
.
5. When the above steps are completed,
a
check of voltage and amperage should be
made of all motors. These readings should
be within 10% of the performance
ratings
given for the specific ambients.

PROCEDURE
With thermostat calling for cooling and set
10° below room temperature, engage disconnect switch(es) to start system.

6. Suction and discharge pressures should
also be checked to ensure that they agree
reasonably well with the pressures shown
in the catalog for the prevailing ambient
conditions.
Also, a suction superheat temperature of 20°F plus or minus 5°F is common for these units when the outdoor ambient is approximately 95°F. This should be
used as a gauge in determining that the
system is not overcharged or has lost some
of its charge.
2. Checkthe voltage atthe compressor motor
connections. If the voltage is 5% below or
10% above the rated voltage or there is a
difference greater than 3% between
phases, shut down the system and call the
power company. A failure to do so may
cause damage to the equipment.
3. After the unit is in operation, it will take
about 30 minutes running time to stabilize
•the system.
.
7. Finally, the thermostat should be checked
out to assure proper operation. Literature
packed with the thermostat and sub-base
will provide information for this check out.
In order to check for a properly working
system, it is recommended that a ther-
trol. When the thermostat calls for "COOLING", current from the "R"terminal is switched
on to the "Y" terminal causing the compressor
contactorto be energized. The main contactor
closes the contacts in the high voltage circuit.
The completion of this circuitwill start both the
outdoor fan motor and the compressor.
With the disconnect on "ON" position, voltage
is supplied to the primary of the control transformer and crankcase
heater.
The control
transformer reduces the voltage from 230 or
208 to 24 volts for the low voltage and the
thermostat circuit. With a single-stage cool/
single-stageheat-thermostat
set in the cooling
position, current is supplied from one side of
the 24 volt secondary of the control transformer
to the "R" terminal of the thermostat. The other
side of this transformer connects to the main
contractor coil through the high pre_ure con-

are needed, as a different thermostat or sub
base may be required.
Be sure the filter is clean. Inspect every 30
days of operation; if obstructed, clean or
replace filter at once. DO NOT RUN WITHOUT A FILTER.
.
Always let the thermostat control the
operation of the system. Never try to "second guess" the thermostat, or tamper with
it. Just set the thermostat at the comfort
level desired AND LEAVE IT ALONE. If it
gets too chilly, just turn the thermostat
up a degree at a time until the desired level
is achieved. Don't turn the thermostat back
and forth.
3. Air conditioners cannot cool off a house as
fast as a furnace heats it. It pulls the
temperature down slowly. Therefore, do
not turn on and expect immediate action. It
may take a day or so to pull down a hot,
moist house when the unit is first installed,
especially after it has been "soaked" in 100110 ° ambient for days.

Keep both the evaporator and condenser
coil surfaces clean. Accumulation of dirt
will restrict the air flow and reduce the
performance of your unit.
It is a good practice when there is a power
outage, especially during severe thunder
storms, to switchoff your unitat the thermostat until the electrical power has been
permanently restored. This could prolong
the life of your compressor.
IMPORTANT.
Keep condensate
drain lines clear and
clean.
All blower fan motors are factory
lubricated and require no attention. The
compressor is hermetically sealed, requiring no attention.
6. Your new air conditioner
Your new air conditioner compressor is
equipped with a Permanent Split Capacitor
motor. Therefore, ALWAYS WAIT AT
LEAST THREE MINUTES AFTER SHUTTING UNIT OFF BEFORE TRYING TO
RESTART. If the unit is started before the
refrigerant pressures have a chance to balance, the compressor motor may trip on its
overload, or,in very rare cases, blowa fuse.
Under any normal operation, this will not
happen. It is most likely to happen if a
thermostat is chattering, or if the unit is
started too quickly. Do not be alarmed if
this happens. Just let the pressures balance
out and then start the unit.
READ CAREFULLY
Your new air conditioner contains a special
compressor
warming electrical circuit to
keep the compressor warm during long off
periods. Do not be alarmed if this creates a
light "humming" sound while the unit is not
running. The "hum" may or may not occur.
Whenever
the power has been disconnected from the unit for Iong..erthan twelve
hours, be sure to turn the power back on
twelve hours before starting the unit. This
will give the compressor warming circuit a
chance to operate and protect the compressor from damage.

you would your automobile if it was exposed to the elements constantly; an occasional coat of wax will give added protection

in the following paragraphs.
THERMOSTAT SETTING:
HEATING LOAD:
For cooling, a temperature of 75 to 78 degrees
is preferred by most people. You may select a
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 ifthe temperature
gets a few degrees warmer during hot weather.
Set the thermostat at the temperature agreeable to the family and leave it there.
Any residential cooling system is the reverse of
a heating system. Family living habits that help
the heating system hurt the cooling system.
The heat pump, furnace, or boiler delivers 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 boiler, fumace, or heat pump.
Do not be concemed if, in the evening, when
the outside temperature drops belowthe 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, ceil-

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
practical and economical to ventilate this concentrate heat and moisture load than it is to

after sundown, while the house and its furnishings continue to give off heat for several
hours.
Wheneveryou plan to have your oven or
range top burners on for more than 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.
To improve the efficiency of the unit, the blower
is operated on atime delay. Depending on the
outside ambient, the blower could delay starting up for 5 to 15 seconds even though the
thermostat calls for cooling. When the thermostat is satisfied, the blower could keep on
running for 1/2to 1-1/2 minutes longer. Do not
be alarmed if you do not hear..tbe blower
