WELCOMETO EFFICIENT COOLING COMFORT

Congratulations on your excellent choice and sound invest- ment in home cooling comfort!

Your new air conditioner represents both tile latest in engi-

neering development and the cuhnination of many years of experience fl'om one of the most reputable manufacturers of

comfort systems.

Your new unit is among the most energy efficient and reli

able air conditioning products available today. To assure its dependability, spend just a few minutes with this booklet now.

Learn about the operation of your air conditioner and the small amount of maintenance it takes to keep it operating at its

peak efficiency.

With minimal care, your air conditioner will provide you and your family with satisfying home comfort -- both now and

for" years to come.

IMPORTANT FACTS To better protect your investment and to eliminate unneces-

sary service calls, familiarize yourself with the following facts:

• Your air conditioning system should never" be operated with

out a clean air filter properly installed. Plan to inspect the filter periodically. A clogged air filter will increase operat-

ing costs and shorten the life of the unit.

• Supply-air and return-air registers should not be blocked. Drapes, fllrniture, and toys are some of the items com- monly found obstructing grilles. Restricted airflow lessens

the unit's efficiency and life span.

• Outdoor units must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand upon it. Do not

allow grass clippings, leaves, or other debris to accu- mulate around or on top of the unit. Maintain a 12 in. mini

mum clearance between tire outdoor unit and tall grass, vines, shrubs, et cetera.

• Your multipurpose indoor thermostat is the control center for your air conditioning system. You should familiarize your

self with its proper operation. Attempting to control the system by other means for" instance, switching the elec-

trical supply power ON and OFF -- may cause damage to the unit.

• Thermostat '_jiggling" causes rapid cycling, which is poten tially damaging to the compressor. Do not move the tern

perature selector on the thermostat for" any reason for at least 5 minutes after the compressor has shut off.

• You may find that you can maintain greater personal com- fort by running tile fan continuously. "Air pockets" can form

due to the structure of the building, placement of regis ters, et cetera. These air pockets may be too cool or warm

for your liking. Continuous fan operation minimizes any temperature differences. Also, systems equipped with elec- tronic air cleaners and/or humidifiers offer" the added ben

efits of having the air continuously cleaned year round, and humidified during the winter season.

• Your air conditioner will remove humidity fl'om your home during tire cooling season. After a few minutes of opera

tion, you should be able to see water trickle from the condensate drain of the cooling coil. Check this occasion- ally to be sure the drain system is not clogged. Of course,

do not expect to see much drainage if you live in a very dry

environn]ent.

OPERATING YOUR AIR CONDITIONER

The operation of your air conditioning system is controlled by the indoor thermostat. You simply adjust the thermostat

and it maintains the indoor" temperature at the level you se- lect. Most thermostats for air-conditioning systems have three controls. These are the temperature control selector, FAN switch, and SYSTEM switch.

The temperature control selector is a dial or button(s) that al- lows you to establish the degree of temperature that you wish

to maintain for your personal comfort. Some thermostats pos- sess two temperature control selectors: one for"setting the tern

perature desired during the cooling cycle, and one to set tile heating operation temperature (if tile accessory electric heater

is used). Typical settings are 78 degrees Fahrenheit for" cool- ing and 68 degrees for heating.

The FAN switch offers two options for controlling tire blower: AUTO and ON. When set to AUTO, the blower will run

during the time the air conditioner is operating. When the FAN switch is set at the ON position, the blower will run

continuously. Typically, the SYSTEM switch on your thermostat offers the

following selections: COOL, OFF, and HEAT. Your thermo- stat may also have a fourth selection, AUTO. The air condi-

tioner will not operate when the SYSTEM switch is set at the OFF position. With the SYSTEM switch set at COOL,

the cooling section of your comfort system will operate when the indoor" temperature rises above the level that you wish to

maintain. With tire SYSTEM switch set at the HEAT posi tion, the accessory electric heater will operate automatically

whenever the indoor" temperature falls below the level that you have selected.

The AUTO selection found on some thermostats provides for automatic changeover between cooling and heating cycles. With

the SYSTEM switch set in the AUTO position, the cooling mode is activated when the indoor temperature rises above

the thermostat cooling temperature setting, or the heating mode will be activated when the indoor temperature drops

below the thermostat setting for" the heating cycle.

I. COOLING CYCLE

When operating in tile cooling cycle, your air conditioner will run until tile indoor" temperature is lowered to the level you

have selected. Oil extremely hot days, your air conditioner will run for" longer periods at a time and have shorter "off'

periods than on moderate days. The following are typical conditions that add extra heat and/or

humidity to your home. Your air conditioner will work longer to keep your home comfortable under these conditions:

• Entrance doors are frequently opened and closed

• Laundry appliances are being operated

• A shower is running

• More than the usual number of people are present in the home

• More than the normal number of electric lights are in use

• Drapes are open on the sunny side of the home

II. HEATING CYCLE

If you own a packaged air conditioner that includes electric heat as an accessory, you need only program your thermostat

for heating. With the SYSTEM switch of your indoor thermostat set to

the HEAT position, tire heating section of your home comfort system will operate until room temperature is raised to the

level you have selected. Of course, the heating unit will have to operate for longer periods to maintain a comfortable envi-

ronment on colder days and nights than on moderate ones.

PERFORMING ROUTINE MAINTENANCE

With the proper maintenance and care, your air conditioner will operate economically and dependably, Maintenance can

be accomplished easily by referring to the following direc tions. However. before performing maintenance, consider these

important safety precautions:

overheat and automatically shut down. In the extreme, the components will fail and need to be replaced, To avoid inefi

ficient or failed operation of your unit, CHECK THE FIE TER(S) EVERY 3 TO 4 WEEKS. Replace filter(s) when nec-

essary, or clean the filter(s) if you have the reusable type. Disposable filters should be replaced by similar, new filters

of the same dimensions, Reusable, permanent filters should be washed in a solution

of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER MUST BE COMPLETELY DRY BE

FORE BEING REINSTALLED. To avoid prolonged shut down of your unit while a filter is drying, you should have an

extra filter on hand. This would allow you to rotate between the two with minimal downtime for" your comfort system. Ex-

tra filters may be purchased fl'om your dealer'. The filter(s) and filter rack fox" a packaged system are sup

plied and installed by the contractor or dealer. Typically, the filter(s) and rack are located in the return-air duct at the out-

door unit or behind the return air grille(s). Have your dealer show you the location of your filter(s) and the procedures for"

removal and replacement. If you have any questions about the removal and/or cleaning

of your filter(s), contact your dealer fox" assistance. If grass clippings, leaves, shrubbery, and debris are kept away

fl'om the unit, minimal care should be sufficient to keep the system flmctioning properly. However, if the outdoor coil be-

comes dirty, use a brush or vacuum cleaner and soft brush attachment to clean the exterior surface. If dirt is deep in the

coil. contact your dealer for service. The outdoor fan motor may have to be disconnected and the top panel removed to

gain access to the coil for thorough cleaning. Do not attempt this yourself.

II. UNIT SUPPORT Your packaged unit should be maintained at a level position.

If its support should shift or settle so that the unit is no longer level, you should correct the condition, Relevel it promptly to

assure condensate drainage out of the unit. If you notice that water or ice collects beneath the unit, arrange for it to be drained away fl'om the unit.

MAIN

I. CHECK THE AIR FILTER

A dirty air filter will cause excessive strain on the compres sor and blower motor, This can cause the components to

BEFORE YOU CALL FOR SERVICE, CHECK FOR THESE EASILY SOLVED PROBLEMS

Check the indoor and outdoor disconnect switches, Verify that circuit breakers are ON.

Check for sufficient airflow. Check the air filter(s) for any ac- cumulations of dirt. Check for blocked return air or supply

air grilles. Be sure grilles are open and unobstructed, Check the settings on your indoor thermostat. If you desire

cooling, see that the temperature control selector is set below room temperature and the SYSTEM switch is on the COOL

or AUTO position. If you require warmth, be sure the tern perature control selector" is set above room temperature and

the SYSTEM switch is at HEAT or AUTO. The FAN switch should be set at ON for continuous blower" operation or AUTO

if you wish the blower to function only while the unit is operating.

If your comfort system still fails to operate, contact your ser- vicing dealer for troubleshooting and repairs. Specify your ap-

parent problem, and state the model and serial numbers of your equipment. (You should have them recorded on page 4

of this booklet.) With this information, your dealer may be able to offer helpfld suggestions over the phone, or save valu-

able time through knowledgeable preparation for the service call.

REGULAR DEALER MAINTENANCE

In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a prop-

erly trained service technician. The inspection (preferably each

year, but at least every other year) should include the

following:

• Routine inspection of air filter(s). Replacement or cleaning as required.

• Inspection and cleaning of the blower wheel, housing, and motor. Service should include proper lubrication of these

conlponents.

• Inspection and, if required, cleaning of indoor (evaporator) and outdoor (condenser) coils.

• Inspection of the indoor coil drain pan, plus the primary and secondary drain lines. Service should include cleaning

if required.

• A check of all electrical wiring and connections.

• A check for secure physical connections of individual corn- ponents within units.

• Operational check of the air conditioning system to deter- mine actual working condition. Necessary repair and/or

adjustment should be performed at this time.
