Introduction: Read Me First!  
This manual will help you understand and service the air conditioner. To help you find the information you need,  
we have divided it into 5 main sections. Each section is divided into chapters with charts, tables and explana-  
tions to help you find and repair problems.  
Section 1: Specifications, tells you about the physical and electrical make up of the unit, as well  
as its heating and cooling capacities. Look in this section to find the correct values for  
components and functions.  
Section 2: Processes and Functions, explains each different part of the cooling and heating  
cycle, and how each control function reacts to changing conditions to keep the room at the set  
temperature range.  
Section 3: Electrical Data, which has fold-out schematic and wiring diagrams so you can find  
the parts you need to check when something is wrong, and see how they should be connected.  
Section 4: Service Procedures, has two main parts, a diagnostic chapter to help you find the  
specific component to replace or adjust, and a chapter with specific procedures and values to  
guide you in checking the electrical components in the unit.  
HOW TO USE THIS MANUAL  
You can use this manual both as a reference to find specific information about the capacity, functions and  
construction of this unit, and as a source of information to help you set up and maintain the unit.  
When this unit is not working properly, and the cause is not known, you can use the procedures in  
Section 3: Servicing Procedures to find the problem, fix it, and restore the unit to its proper functioning.  
This air conditioner has many helpful self diagnostic features to help you identify problem areas quickly.  
So you will be ready when a problem happens, we suggest you look this manual over and become familiar with it  
by following these steps:  
1.  
2.  
Look at the TABLE OF CONTENTS to get an idea of what is in this manual and where to find it.  
Look at the chapter about TROUBLE SHOOTING, so you are familiar with the way the flow  
charts work. They are designed to guide you quickly through the possible causes for each kind of  
problem that is likely to happen to the Unit. Particularly read the introduction to this section, and  
the parts about the self-diagnosis and error codes which show on the display.  
3.  
4.  
Look at the chapter about CHECKING ELECTRICAL COMPONENTS. You already know  
about most of these procedures. This chapter gives you the specific values and methods for  
these components. If you don’t know some of these procedures, you can easily learn them here.  
Read the Instruction Manual! The Instruction Manual is included here because it helps you help  
the user to set the temperature controls properly and know how to take care of any simple  
problems that may happen, as well as know when to call for service. The Instruction Manual also  
has illustrations, care, and installation information not found in the rest of the service manual. It is  
short, and if you read it carefully, you will be able to answer the customers questions easily, and  
also know the most efficient ways for setting times and temperatures.  
Please use this manual to make your work easier, keep the air conditioner functioning well, and keep your  
customers satisfied.

Wind Shield for “CL” Model  
IMPORTANT  
0426_C_I  
It is recommended to use wind shields for  
“CL” model (Fig. 6). “CL” model is designed  
to use in low outdoor temperature conditions.  
Fig. 5  
Wind shield  
(air discharge side)  
General  
When the outdoor unit is installed in a position  
exposed to strong wind (like seasonal winds  
with low air temperature in winter), wind shield  
must be installed on the outdoor unit.  
This unit is designed so that the fan of the  
outdoor unit runs at low speed when the air  
conditioner is operated at low outdoor air  
temperatures. When the outdoor unit is ex-  
posed to strong wind, the system pressure  
drops because of the freeze protector.

8. INSTALLATION INSTRUCTIONS  
3) Electrical Wiring  
(7) Regulations on wire diameters differ from  
locality to locality. For field wiring rules,  
please refer to your LOCAL ELECTRI-  
CAL CODES before beginning. You must  
ensure that installation complies with all  
relevant rules and regulations.  
General Precautions on Wiring  
(1) Before wiring, confirm the rated voltage  
of the unit as shown on its nameplate,  
then carry out the wiring closely following  
the wiring diagram.  
(2) Provide a power outlet to be used exclu-  
sively for each unit, and a power supply  
disconnect and circuit breaker for  
overcurrent protection should be pro-  
vided in the exclusive line.  
(8) To prevent malfunction of the air condi-  
tioner caused by electrical noise, care  
must be taken when wiring as follows:  
ã The inter-unit control wiring and the remote  
control wiring (option) should be wired  
apart from the inter-unit power wiring.  
(3) To prevent possible hazards from insula-  
tion failure, the unit must be grounded.  
(4) Each wiring connection must be done in  
accordance with the wiring system dia-  
gram. Wrong wiring may cause the unit  
to misoperate or become damaged.  
(5) Do not allow wiring to touch the refriger-  
ant tubing, compressor, or any moving  
parts of the fan.  
ã It is recommended that shielding wires or  
twisted pair wires be used for the remote  
control and the inter-unit control wiring if  
the air conditioner is installed where it is  
exposed to the influence of electrical and/  
or electro-magnetic noise.  
(6) Unauthorized changes in the internal  
wiring can be very dangerous. The manu-  
facturer will accept no responsibility for  
any damage or misoperation that occurs  
as a result of such unauthorized changes.

11. PROCESSES AND FUNCTIONS  
(1) Room Temperature Control  
The Unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF.  
This process is controlled by the thermostat located in the remote control unit.  
The figures on this and the next pages show how each part of the system performs when the  
room temperature changes and the thermostat activates the compressor to start (thermo ON)  
or stop (thermo OFF). Fig. 8 shows about the cooling cycle.

Chart Summary and Explanations  
Once the compressor starts, it keeps running for 5 minutes.  
Once the compressor stops, it will not start running again for 3 minutes.  
If you change the operation mode during the cooling cycle, the control circuit stops the  
compressor for 3 minutes.  
For 5 minutes after the compressor is first turned on, and for 3 minutes after it is turned off,  
the compressor is not controlled by the room sensor.  
Thermo ON: When room temperature rises 1 °F above the set temperature T˚, (T ˚+1 °F):  
Compressor ON  
Thermo OFF: When the room temperature is equal to or below the set temperature T˚:

11. PROCESSES AND FUNCTIONS  
(2) Freeze Prevention  
Freeze Prevention keeps the indoor heat exchange coil from freezing. Freezing reduces the  
efficiency of the unit, and frost buildup on the coil blocks cool air circulation from the indoor  
unit’s fan.

(4) Outdoor Fan Speed Control  
1) C4232 Type  
• In low outdoor temperature, the outdoor fan is set automatically from HIGH to LOW to  
prevent the indoor heat exchanger from freezing.  
• When the outdoor temperature falls below 78 °F, the outdoor fan is set from HIGH to  
LOW automatically. When the outdoor temperature rises to 82 °F, the outdoor fan is  
set from LOW to HIGH automatically.  
2) CL4232 Type  
• In low outdoor temperature, the outdoor fan is set automatically from HIGH to MED,  
LOW to prevent the indoor heat exchanger from freezing.  
• When the outdoor temperature falls below 77 °F, the outdoor fan is set from HIGH to  
MED automatically. When the outdoor temperature rises to 81 °F, the outdoor fan is  
set from MED to HIGH automatically.  
• When the outdoor temperature falls below 59 °F, the outdoor fan is set from MED to  
LOW automatically. When the outdoor temperature rises to 63 °F, the outdoor fan is  
set from LOW to MED automatically.  
• When the outdoor temperature falls below 47 °F, the outdoor upper fan is set from  
LOW to OFF and Lower fan is set from LOW to MED antomatically. When the outdoor  
temperature rises to 50 °F, the outdoor upper fan is set from OFF to LOW and Lower  
fan is set from MED to LOW antomatically.

12. SERVICE PROCEDURES  
(1) Troubleshooting  
1) Check before and after Troubleshooting  
Many problems may happen because of wiring or power supply problems, so you  
should check these areas first. Problems here can cause false results in some of  
the other tests, and so should be corrected first.  
1 Check power supply wiring  
(a) Single-phase  
Check that power supply wires are correctly connected to terminal No. 1  
through No. 4 on the 4P terminal plate in the indoor unit and L1 and L2 on  
the 6P terminal in the outdoor unit.  
2 Check inter-unit wiring  
Check that inter-unit control wiring (AC 230 - 208 V Line voltage) is cor-  
rectly connected between the indoor unit and outdoor unit.
