1 Safety Precautions
The following are instructions that you must follow in order to prevent accidents during work, and to ensure the safety of the
repaired product.
Hazard and damages that may result from ignoring instructions are classified and explained, below.
The following labels describe the types of rules that need to be followed.
This section warns of the urgent danger of death or serious injury.
This section warns of the risk of death or serious injury.
This section warns of the risk of injury or damage to property.
This label shows a “reminder” action to be paid attention to.
This label shows a “prohibited” action.
This label shows a “compulsory” action to be followed without fail.
Be sure to discharge remaining refrigerant from the refrigeration unit.
Discharge refrigerant outdoors where there is no fire source.
Be sure to instruct the customer not to approach the place of discharge, and not to use fire.
Always use a pipe cutter for removing pipes.
If you use a welding machine, the refrigerant remaining in the pipe or compressor could catch fire and explode.
Pipes must be blown out with nitrogen before welding, to discharge any remaining refrigerant.
Always use the swage lock for sealing after filing with refrigerant.
If you use a welding machine, the refrigerant could catch fire and explode.
Ventilation close to the floor surface is required, as the refrigerant (R600) is heavier than air.
In particular, the basement must be adequately ventilated.
“Measurement/adjustment of refrigerant refill quantity” in a service must be performed outdoors where
there is no fire source.
Otherwise, you could run the risk of fire/explosion.
Use always a gas alarm.
If any refrigerant remains in work area, there will be a risk of fire/explosion.
Prohibited
Never use a naked flame in a place where any refrigerant might remain.
Prohibited
Do not leave the removed faulty compressor in doors.

Remove power plug
Before repair
Make sure to cut off the power line before disassembly, parts replacement and assembly.
Otherwise, electrical shock or injury may occur.
Electric shock hazard
Be careful of electrical shocks
Be careful of electric shock from live parts or electrical lead terminals when conducting voltage measurement and
other electrical servicing.
Voltage of the control board is approximately 280V when power is ON.
Do not touch live parts.
When replacing parts, do not touch live parts for at least 3 minutes after disconnecting the plug the power supply.
(A little time is required for electrical discharge of the condenser)
Use only fuses specified
When replacing fuses, use only specified in the circuit diagram. The use of nonspecific fuses may cause fire or
malfunction.
Punch the pipes of the faulty compressor securely.
Otherwise, the refrigerant remaining in the compressor oil might leak out during transporting and could catch fire
and explode.
Discharge refrigerant completely from the used service can for disposal in an outdoor place where there is no
fire source.
Otherwise, you could run the risk of fire/explosion.
Prohibited
Do not damage the refrigeration circuit (piping) of the refrigerator.
As the refrigerant is flammable, any damage could lead to fire/explosion.
If the refrigeration circuit is damaged, do not touch the refrigerator or use a naked flame. Open windows for
Ventilation.
As the refrigerant is flammable, any damage could lead to fire/explosion.
Disposal of a faulty compressor must be performed outdoors where there is no fire source.
The quantity of refrigerant in a service can carried in the vehicle must be the least possible, and below the
[regulation][regulated] limit. Keep the service can upright and below 40°C. (Quantity on board: 1.5kg or
below)
Use a designated part
Make sure to use a designated part when the part is marked( ) in circuit diagrams and parts lists.
Otherwise,smoke,fire or failure may occur.
Always conduct a safety inspection after completing service
And check the parts are reassembled correctly. Also confirm other fixings and wiring, for deterioration. Replace as
required. Always use a megohmmeter to measure the insulating resistance between both terminals of the power
plug and the earth terminal, and plug the power supply in after first confirming 1MΩor above.
When setting, check that the power cord or power plug is not jammed or pushed against the rear of the refrigera-
tor.
If the power cord or the power plug is damaged or loose, take appropriate measures such as replacing.
If the pins of the plug or the area the pins attach to are dirty, make sure they are cleaned thoroughly.

Dragging the refrigerator will damage the floor. For flooring that may become easily damaged put a protective
board in place.
Do not scrape the metal rails
High temperature hazard
Take care of very hot parts
The compressor, pipes etc. can be very hot during operation and directly after stopping. Also, the heater can be
very hot during power supply and immediately after power supply is stopped. Be careful not to burn yourself by
touching very hot parts.
High temperature hazard
Take care of very hot parts after welding
Pipes etc., are very hot after welding. Be careful not to burn yourself by touching very hot parts.
Take care when filling/discharging refrigerant
Liquid refrigerant directly touching the skin may cause frostbite.

5 Technical Descriptions
5.1. Temperature control for each compartment
5.1.1. FC temperature control
The compressor is turned on and off detecting the FCC temperature.
Operation: The setting temperature “-25°C” to “-17°C”, 9 levels change
Detection: FCC, ATC sensor
1. When power supply is turned on, FC temperature is displayed on the panel PCB by reading FC setting data of microcomputer
memories. The data is written in memory area of microcomputer, 5 seconds after FC setting change. After that, FC tempera-
ture is controlled by setting FC temperature of the panel PCB.
The FC setting data is memorized, though the power supply of this product is turned off. The setting temperature is fixed, after
the time to have set temperature change passed more than 5 seconds.
2. The setting temperature
The temperature, when it set on -21°C
The OFF/ON temperature value corresponding to each ATC temperature is as shown in the next graph.
5.1.2. PC temperature control
PC damper is controlled by the PCC temperature.
1. When power supply is turned on, PC temperature is displayed on the panel PCB by reading PC setting data of microcomputer
memories.
The data is written in memory area of microcomputer, 5 seconds after PC setting change. After that, PC temperature is con-
trolled by setting PC temperature of the panel PCB. The PC setting data is memorized though the power supply of this appli-
ance is turned off.
