A
WARNING
To prevent personal injury, death, or property
damage, read and follow all instructions and
warnings, including labels shipped with or attached to the unit before operating your new air
conditioner.
YOUR COMFORT SYSTEM
Identifying Your System
Take the time to familiarize yourself with the type of system you
have. This knowledge will be of use in understanding the basic
operation of your new air conditioner.
The type of air conditioner you have purchased is a split system.
The split -system type has an indoor and an outdoor unit, each of
which contains a coil. These units are interconnected by refrigerant tubes. (See Fig. 1.)
Each unit has a rating plate affixed to it which provides necessary
information for specific identification of a unit. You should
familiarize yourself with the product, model, and serial numbers
listed on each rating plate. Record them for future reference on
the last page of this booklet.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
• Incorporated in your air conditioner is the latest in scroll compressor technology. Become familiar with characteristic start up
and operational sounds.

• Supply-air and return-air registers should not be blocked.
Drapes, furniture, and toys are some of the items commonly
found obstructing registers. Restricted airflow lessens the unit's
efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not cover
the unit, lean anything against it, or stand on it. Do not allow grass
clippings, leaves, or other debris to accumulate around or on top
of the unit. Maintain a 12-in. minimum clearance between the
outdoor unit and tall grass, vines, shrubs, etc.

after the compressor has shut off.
• You may find that you can maintain greater personal C{)mfort
by running the fan continuously. Air pockets can form due to the
structure of the house, placement of registers, etc. These
pockets may be too cool orwarm for youtliking. Continuous fan
operation minimizes any temperature differences. Also, systems
equipped with~lectronic or mechanical air cleaners
and/or humidifiers offer the added benefits of having the air

offers the advantage of exhausting stale air from the home and
AIR CONDITIONER
allowing fresh air in from the outdoors while minimizing heat
loss.
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 select. Most
thermostats have three controls: a temperature control selector,
a FAN control, and a SYSTEM or MODE control. Fig. 2 and 3
show typical Carrier thermostats.
• Your system may also be equipped with awning system which
allows individual control over the temperatures of separate areas
of your home.
• Your air conditioner will remove humidity from your home
during the cooling season. After a few minutes of operation, you
should be able to see water trickle from the condensate drain of
the cooling coil. Check this occasionally to be sure the drain
system is not clogged. Of course, don't expect to see much
drainage if you live in a very dry environment
The temperature control selector is a dial, lever, or set of buttons
that allows you to select the temperature you wish to maintain for
your personal comfort. Some thermostats possess two temperature control selectors: one for setting the temperature desired during cooling operation, and one for setting the temperature for
heating operation.

HEATING MODE
Fig. 4-Main
With the SYSTEM or MODE control of your indoor thermostat
set to HEAT, the furnace or other heating equipment of your
home comfort system will operate until room temperature is
raised to the level you have selected. Of course, the heating
equipment will have to operate for longer periods to maintain a
comfortable environment on cooler days and nights than on
moderate ones.
Electrical Disconnect
Refer to your furnace User's Manual for specific information on
heating operation.
The FAN control offers two options for controlling the blower:
AUTO and ON. When set to AUTO, the blower runs only while
the thermostat operates the cooling or heating equipment.
When the FAN control is set to ON, the blower runs continuously-regardless
of whether the cooling or heating equipment
is operating.
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 directions.
However, before performing maintenance, consider these
important safety precautions.
Typically, the SYSTEM or MODE control on your thermostat
offers the following selections: COOL, OFF, and HEAT. Your
thermostat may also have a fourth selection: AUTO. Neither the
cooling or heating equipment operate when the SYSTEM or
MODE control is set to OFF. With the SYSTEM or MODE
control set to COOL, your air conditioner will operate when the
indoor temperature rises above the level that you wish to maintain.
With the SYSTEM or MODE control set to HEAT, your furnace
or other heating equipment will operate automatically when the
indoor temperature falls below the level that you have selected.
A
WARNING
To prevent personal injury or death disconnect
all electrical power to the indoor air handler or
furnace before removing access panels to perform maintenance. Disconnect power to both the
indoor and any outdoor units. NOTE: there may
be more than 1 electrical disconnect switch.
The AUTO selection found on some thermostats provides for
automatic changeover between cooling and heating modes. With
the SYSTEM or MODE control set to AUTO, your air conditioner will operate when the indoor temperature rises above the
thermostat cooling temperature setting, and your furnace or other heating equipment will operate when the indoor temperature
drops below the thermostat setting for the heating cycle.
A
CAUTION
Although special care has been taken to minimize
sharp edges in the construction of your unit, be
extremely careful when handling parts or reaching into the unit.
Your thermostat may be PROGRAMMABLE or NON-PROGRAMMABLE. A NON-PROGRAMMABLE thermostat does
not allow the temperature settings to be varied throughout the day
or week without physically changing the settings. A PROGRAM-.
MABLE thermostat allows various daily temperature changes to
be preset. During the winter, for example, you may wish to "set
back" the temperature of your home at night, then have the temperature return to normal prior to waking up. The home's temperature can then be lowered again during the day when no one is at
home, but again be at peak comfort level when your family
returns home. During the summer, the opposite changes might be
programmed. When properly used, the programming can result in
energy savings on your home's heating and cooling.

required. Ocean mist/breeze carries salt, which is corrosive to
most metals. Although your new unit is made of galvanized
metal and is protected by top-grade paint, you should take the
precaution of additional maintenance which consists of
periodically washing the unit. By washing all exposed surfaces
and coil approximately every 3 months, you will be adding
additional life to your unit. Consult your installing contractor
for proper intervals/procedures for your geographic area or service contract.
A dil.:tYi,<$i~terwill cause excessive;strain:()n1h~ compressor

,,4.;\MEEKS. Replace filter(s) when necessary, or clean the filter(s)
if you have the reusable type.
Disposable filters should be replaced by similar, new filters of
the same dimensions.
UNIT SUPPORT
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 BEFORE
BEING REINSTALLED. To avoid prolonged shutdown of your
unit while a filter is drying, you should have an extra filter on
hand. This allows you to rotate between the two with minimal
downtime for your comfort system. Extra filters may be
purchased from your dealer.
Your split-system outdoor unit should be maintained in 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 proper water drainage out
of the unit. If you notice that water or ice collects beneath
the unit, arrange for it to be drained away from the
unit.
There are no filters in the outdoor unit of a split-system. If your
indoor unit is a gas or oil furnace, refer to your furnace User's
Manual for filter location and procedures for cleaning or
replacement.
BEFORE YOU REQUEST A SERVICE
CALL
CHECK FORTHESE
PROBLEMS:
If your system includes an indoor fan coil unit, the filter may be
located in the unit where it connects with the return-air duct or
plenum. (See Fig. 5.) Remove the filter cover plate by sliding
latches toward center of plate. Lift filter to clear lower flange.
Filter is spring-loaded and will pop out. Reinstall filter, being
certain to secure filter behind lower flange. When reinstalling
cover plate, secure plate behind upper flange then slide tabs
outward.
EASILY SOLVED
• Check the indoor and outdoor disconnect switches. Verify that
circuit breakers are ON or that fuses have not blown.
• Check for sufficient airflow. Check the air filter(s) for any
accumulations of dirt. Check for blocked return-air or supply-air
registers. Be sure registers are open and unobstructed.
• Check the settings on your indoor thermostat. If you desire
cooling, make sure that the temperature control selector is set
below room temperature and the SYSTEM or MODE control is
set to COOL or AUTO. If you require warmth, be sure the temperature control selector is set above room temperature and the
SYSTEM or MODE control is set to HEAT or AUTO. The FAN
control should be set to ON for continuous blower operation or
AUTO if you wish blower to function only while your heating or
cooling equipment is operating.
The indoor fan coil unit may be located in the attic. In
this instance the filter could be located behind the return air
grille. Access the filter by removing two screws from return
air grille.
ELECTRONIC AIR CLEANER
If your system contains an ElectronicAir Cleaner consult the
User's Manual for specific care of that product.
If coil cleaning is required, call your dealer for service. It may
be necessary to clean the coil with a detergent solution and rinse
it with water. This could require the removal of the coil. You
should not attempt this yourself.
If your comfort system still fails to operate, turn your system off
and contact your servicing dealer for troubleshooting and
repairs. Specify your apparent problem, and state the model and
serial numbers of your equipment. (You should have them
recorded the last page of this booklet.) With this information,
your dealer may be able to offer helpful suggestions over the
phone or save valuable time through know ledgeable preparation
for the service call.
OUTDOOR COIL
REGULAR DEALER MAINTENANCE
If grass clippings, leaves, shrubbery, and debris are kept away
from the outdoor unit, minimal care should be sufficient to keep
the system functioning properly. For proper drainage, debris
must be removed periodically from the base pan. However, if the
outdoor coil becomes dirty, use a vacuum cleaner with soft brush
attachment to clean the exterior surface. Vacuum coil surface
with an up and down motion. Be careful not to bend or damage
fins.
In addition to the routine maintenance that you perform, your home
comfort system should be inspected
regularly by a properly trained service technician. The inspection
(preferably each year, but at least
every other year) should include the
following:
INDOOR COIL
If the split-system coil has only been operated with a clean filter
in place, it should require minimal cleaning.
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.
