1 SAFETY PRECAUTIONCAUTIONS RELATED TO NEW REFRIGERANTUse new refrigerant pipes.In case of using the existing pipes for R22, be careful withthe followings.· For RP4, 5 and 6, be sure to perform replacement operationbefore test run.· Change flare nut to the one provided with this product.Use a newly flared pipe.· Avoid using thin pipes.Make sure that the inside and outside of refrigerantpiping is clean and it has no contaminationsuch as sulfur hazardous for use, oxides, dirt,shaving particles, etc.In addition, use pipes with specified thickness.Contamination inside refrigerant piping can cause deteriorationof refrigerant oil etc.Store the piping to be used during installationindoors and keep both ends of the piping sealeduntil just before brazing. (Leave elbow joints, etc.in their packaging.)If dirt, dust or moisture enter into refrigerant cycle, that cancause deterioration of refrigerant oil or malfunction of compressor.Use ester oil, ether oil or alkylbenzene oil (smallamount) as the refrigerant oil applied to flaresand flange connections.If large amount of mineral oil enter, that can cause deteriorationof refrigerant oil etc.Charge refrigerant from liquid phase of gascylinder.If the refrigerant is charged from gas phase, compositionchange may occur in refrigerant and the efficiency will belowered.Do not use refrigerant other than R410A.If other refrigerant (R22 etc.) is used, chlorine in refrigerantcan cause deterioration of refrigerant oil etc.Use a vacuum pump with a reverse flow checkvalve.Vacuum pump oil may flow back into refrigerant cycle andthat can cause deterioration of refrigerant oil etc.Use the following tools specifically designed foruse with R410A refrigerant.The following tools are necessary to use R410A refrigerant.Tools (for R410A)Gauge manifold Flare toolCharge hoseSize adjustment gaugeGas leak detector Vacuum pump adaptorTorque wrenchElectronic refrigerantcharging scaleKeep the tools with care.If dirt, dust or moisture enter into refrigerant cycle, that cancause deterioration of refrigerant oil or malfunction of compressor.Do not use a charging cylinder.If a charging cylinder is used, the composition of refrigerantwill change and the efficiency will be lowered.Ventilate the room if refrigerant leaks duringoperation. If refrigerant comes into contact witha flame, poisonous gases will be released.[1] Cautions for service(1) Perform service after collecting the refrigerant left in unit completely.(2) Do not release refrigerant in the air.(3) After completing service, charge the cycle with specified amount of refrigerant.(4) When performing service, install a filter drier simultaneously.Be sure to use a filter drier for new refrigerant.[2] Additional refrigerant chargeWhen charging directly from cylinder· Check that cylinder for R410A on the market is syphon type.· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)2

UnitGravimeter[3] Service toolsUse the below service tools as exclusive tools for R410A refrigerant.No.Specifications1 Gauge manifold ·Only for R410A·Use the existing fitting specifications. (UNF1/2)·Use high-tension side pressure of 5.3MPa·G or over.2 Charge hose ·Only for R410A·Use pressure performance of 5.09MPa·G or over.3 Electronic scale4 Gas leak detector ·Use the detector for R134a, R407C or R410A.5 Adaptor for reverse flow check ·Attach on vacuum pump.6 Refrigerant charge base7 Refrigerant cylinder ·Only for R410A Top of cylinder (Pink)Cylinder with syphon8 Refrigerant recovery equipment3

If there is not any other wrong when trouble occures, emergency operation starts as the indoor control board switch (SWE)is set to ON.During the emergency operation the indoor unit is as follows;(1) Indoor fan high speed operation (2) Drain-up machine operation2. When emergency operating for COOL or HEAT, setting of the switch (SWE) in the indoor control p.c.board and outdoor unitemergency operation are necessary.3. Check items and notices as the emergency operation(1) Emergency operation cannot be used as follows;• When the outdoor unit is something wrong.• When the indoor fan is something wrong.• When drain over flow protected operation is detected during self-diagnosis. (Error code : P5)(2) Emergency operation will be serial operation by the power supply ON/OFF.ON/OFF or temperature, etc. adjustment is not operated by the remote controller.(3) Do not operate for a long time as cold air is blown when the outdoor unit starts defrosting operation during heat emergencyoperation.(4) Cool emergency operation must be within 10 hours at most. It may cause heat exchanger frosting in the indoor unit.(5) After completing the emergency operation, return the switch setting, etc. in former state.(6) Since vane does not work at emergency operation, position the vane manually and slowly.31
