SAFETY PRECAUTI CAUTIS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R0C Do not use the existing refrigerant piping. The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit. Use liquid refrigerant to seal the system. If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop. Use low residual oil piping If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricant will result. Store the piping to be used during installation indoors with keep both ends 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 ESTR, ETHER or HAB as the lubricant to coat flares and flange connection parts. If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc. Do not use a refrigerant other than R0C. If another refrigerant (R, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration. Use a vacuum pump with a reverse flow check valve. The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricant deterioration. Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. [] Cautions for service After recovering the all refrigerant in the unit, proceed to working. Do not release refrigerant in the air. After completing the repair service, recharge the cycle with the specified amount of liquid refrigerant. [] Refrigerant recharging () Refrigerant recharging process Direct charging from the cylinder. R0C cylinder are available on the market has a syphon pipe. Leave the syphon pipe cylinder standing and recharge it. (By liquid refrigerant) Unit Gravimeter () Recharge in refrigerant leakage case After recovering the all refrigerant in the unit, proceed to working. Do not release the refrigerant in the air. After completing the repair service, recharge the cycle with the specified amount of liquid refrigerant.

Cautions for units utilizing refrigerant R0A Do not use the existing refrigerant piping. The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit. Use low residual oil piping If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricant will result. Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.) If dirt, dust or moisture enter into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor. Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigerant oil applied to flares and flange connections. If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc. Charge refrigerant from liquid phase of gas cylinder. If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered. Use a vacuum pump with a reverse flow check valve. Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc. Use the following tools specifically designed for use with R0A refrigerant. The following tools are necessary to use R0A refrigerant. Tools for R0A Gauge manifold Flare tool Charge hose Size adjustment gauge Gas leak detector Vacuum pump adaptor Torque wrench Electronic refrigerant charging scale Keep the tools with care. If dirt, dust or moisture enter into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor. Do not use a charging cylinder. If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered. Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. Do not use refrigerant other than R0A. If other refrigerant (R etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
[] Cautions for service () Perform service after collecting the refrigerant left in unit completely. () Do not release refrigerant in the air. () After completing service, charge the cycle with specified amount of refrigerant. () When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant. [] Additional refrigerant charge When charging directly from cylinder Check that cylinder for R0A on the market is syphon type.

<Output pulse signal and the valve operation> Output (Phase) { { { { Output Closing a valve : Opening a valve : The output pulse shifts in above order.. When linear expansion valve operation stops, all output phase become.. At phase interruption or when phase does not shift in order, motor does not rotate smoothly and motor locks and vibrates. ➁ Linear expansion valve operation D C Valve position (capacity) A E Close Open 000 pulse Opening a valve all the way When the switch is turned on, 00 pulse closing valve signal will be send till it goes to A point in order to define the valve position. When the valve move smoothly, there is no noise or vibration occurring from the linear expansion valve : however, when the pulse 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 screw driver handle while putting the screw driver to the linear expansion valve. B Pulse number Extra tightning (0~00pulse) ➂ Trouble shooting Symptom Check points Operation circuit failure of the micro nect LED for checking. Disconnect the connector on the controller board, then con- processor. T LED Pulse signal will be sent out for 0 seconds as soon as the main switch is turned on. If there is LED with lights on or lights off, it means the operation circuit is abnormal. Countermeasures Exchange the indoor controller board at drive circuit failure. Linear expansion valve mechanism is locked. Short or breakage of the motor coil of the linear expansion valve. Valve doesn't close completely (thermistor leaking). Wrong connection of the connector or contact failure. Motor will idle and make ticking noise when motor is operated Exchange the linear while the linear expansion valve is locked. This ticking sound expansion vale. is the sign of the abnormality. Measure the resistance between the each coil (red-white, red-orange, brown-yellow, brown-blue) using a tester. It is normal if the resistance is in the range of 0'+0%. To check the linear expansion valve, operate the indoor unit in fan mode and at the same time operate other indoor units in cooling mode, then check the pipe temperature <liquid pipe temperature> of the indoor unit by the outdoor multi controller board operation monitor. During fan operation, linear expansion valve is closed completely and if Liquid pipe thermistor Linear expansion valve there are some leaking, detecting temperature of the thermistor will go lower. If the detected temperature is much lower than 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, if the leakage is small and not making any trouble. Check the color of lead wire and missing terminal of the connector. Exchange the linear expansion valve. If large amount of thermistor is leaked, exchange the linear expansion valve. Disconnect the connector at the controller board, then check the continuity.
