Carrier 38CKC042 Air ユーザーズマニュアル

 

 

Congratulations on your excellent choice and sound investment 
in home cooling comfort!

Your new air conditioning unit represents both the latest in engi-
neering development and the culmination of many years of 
experience from one of the most reputable manufacturers of 
comfort systems.

Your new unit is among the most energy-efficient and reliable 
air conditioning products available today. To assure its depend-
ability, 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 new air conditioner will provide you and 
your family with cool comfort—both now and for years to come.

 

Recognize safety information. This is the safety-alert symbol 

. 

When you see this symbol on the unit or in instructions and man-
uals, be alert to the potential for personal injury.

Understand the signal word DANGER, WARNING, or CAU-
TION. These words are used with the safety-alert symbol. DAN-
GER identifies the most serious hazards which 

 

 result in 

severe personal injury or death. WARNING signifies hazards 
that 

 

 result in personal injury or death. CAUTION is used 

to identify unsafe practices which 

 

 result in minor person-

al injury or product and property damage.

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 split-system type has an indoor and an outdoor unit, each of 
which contains a coil. These units are interconnected by refrig-
erant 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 ref-
erence on the last page of this booklet.

 

To better protect your investment and to eliminate unnecessary 
service calls, familiarize yourself with the following facts:

• Your air conditioning system should never be operated without 
a clean air filter properly installed. Plan to inspect the filter peri-
odically. A clogged air filter will increase operating costs and 
shorten the life of the unit.

• Supply-air and return-air registers should not be blocked. 
Drapes, furniture, and toys are some of the items commonly 
found obstructing grilles. Restricted airflow lessens the unit’s effi-
ciency 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.

• Your multipurpose indoor thermostat is the control center for 
your air conditioning system. You should familiarize yourself 
with its proper operation. Attempting to control the system by 
other means—for instance, switching the electrical supply power 
ON and OFF—may cause damage to the unit.

• Thermostat “jiggling” causes rapid-cycling, which is potential-
ly damaging to the compressor. Do not move the temperature 
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 comfort 
by running the fan continuously. Air pockets can form due to the 
structure of the house, placement of registers, etc. These air pock-
ets may be too cool or warm for your liking. Continuous fan oper-
ation minimizes any temperature differences. Also, systems 
equipped with electronic or mechanical air cleaners and/or 
humidifiers offer the added benefits of having the air continuously 
cleaned year-round, and humidified during the winter season.

• A system equipped with a heat or energy recovery ventilator 
offers the advantage of exhausting stale air from the home and 
allowing fresh air in from the outdoors while minimizing heat 
loss.
