2 SAFETY PRECAUTION
Precautions for devices that use R407C refriqerant.
Cautions for connecting with R407C outdoor unit..Caution:· Do not use R407C piping after use it for R22.· Do not use the existing refrigerant piping.
-The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause therefrigerator oil of the new unit to deteriorate.
· Use refrigerant piping made of C1220(CU-DHP) phosphorus deoxidized copper as specified in the JIS H3300“Copper and copper alloy seamless pipes and tubes”. In addition, be sure that the inner and outer surfaces of thepipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any othercontaminant.
-Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate.· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.) -If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections.-The refrigerator oil with degrade if it is mixed with a large amount of mineral oil.
· Use liquid refrigerant to fill the system.-If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performancemay drop.
· Do not use a refrigerant other than R407C.-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.
· Use a vacuum pump with a reverse flow check valve. Evacuate sufficiently for one hour, leave it put for another onehour and be sure not to down the vacuum degree.
· Do not use the following tools that are used with conventional refrigerants.
No. Tool name Specifications1 Gauge manifold ·Only for R407C.
·Use the existing fitting SPECIFICATIONS. (UNF7/16)·Use high-tension side pressure of 35kgf/cm2 or over.
2 Charge hose ·Only for R407C.·Use pressure performance of 52kgf/cm2 or over.
3 Electronic scale4 Gas leak detector ·Use the detector for R134a or R407C.5 Adapter for reverse flow check. ·Attach on vacuum pump.6 Refrigerant charge base.7 Refrigerant cylinder. ·For R407C ·Top of cylinder (Brown)
·Cylinder with syphon8 Refrigerant recovery equipment.
· Do not use a charging cylinder.-Using a charging cylinder may cause the refrigerator to deteriorate.
· Be especially careful when managing the tools.-If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
· For gas leak detecter, be sure to use it only for HFC refrigerant. (same as for R134a)· If moving, put the cap on the flare at indoor unit side to prevent to mix dust or water.· If measures on refrigerant leackage or repair servicing, be sure to refer the manual for outdoor unit.

Symptom Check points
Operation circuitfailure of the microprocessor.
Disconnect the connector on the controller board, thenconnect LED for checking.
Pulse signal will be sent out for 10 seconds as soon as themain switch is turn on. If there is LED with lights on or lightsoff, it means the operation circuit is abnormal.
Countermeasures
Exchange the indoorcontroller board at drivecircuit failure.
To check the linear expansion valve, operate the indoor unitin fan mode and at the same time operate other indoor unitsin cooling mode, then check the pipe temperature <liquid
pipe temperature> of the indoor unit by theoutdoor multi controller board operationmonitor. During fan operation, linearexpansion valve is closed completely and ifthere are some leaking, detectingtemperature of the thermistor will go lower.If the detected temperature is much lowerthan the temperature indicated in the
remote controller, it means the valve is not closed all the way.It is not necessary to exchange the linear expansion valve, ifthe leakage is small and not making any trouble.
Thermistor
Linearexpansionvalve
Motor will idle and make ticking noise when motor is operatedwhile the linear expansion valve is locked. This ticking soundis the sign of the abnormality.
Check the color of lead wire and missing terminal of theconnector.
Exchange the linearexpansion valve.
Exchange the linearexpansion valve.
If large amount ofthermistor is leaked,exchange the linearexpansion valve.
Disconnect the connectorat the controller board,then check the continuity.
Measure the resistance between the each coil (red-white,red-orange, brown-yellow, brown-blue) using a tester. It isnormal if the resistance is in the range of 150'+10%.
Short or breakage ofthe motor coil of thelinear expansionvalve.
The output pulse shift in above order.❈ 1. When linear expasion valve operation stops, all output phase
become OFF.2. At phase interruption or when phase does not shift in order,
motor does not rotate smoothly and motor lock, and vibrates.
❈ When the switch is turned on, 2200 pulse closeing valve signalwill be send till it goes to A point in order to define the valveposition.
When the valve move smoothly, there is no noise or vibrationoccurring from the linear expansion valve ; however, when thepulse number moves from E to A or when the valve is locked,more noise can be heard than normal situation.
❈ Noise can be detected by placing the ear against the screwdriver handle while putting the screw driver to the linearexpansion valve.
