3 SAFETY PRECAUTION -. ALWAYS OBSERVE FOR SAFETY Before obtaining access to terminal, all supply circuits must be disconnected. -. CAUTIONS RELATED TO NEW REFRIERANT Cautions for units utilising refrigerant R07C 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 charge 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 ESTER, 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 R07C. 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.

4 [] 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. R07C cylinder are available on the market has a syphon pipe. Leave the syphon pipe cylinder standing and recharge it. (By liquid refrigerant) Unit ravimeter () 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. [] Service tools Use the below service tools as exclusive tools for R07C refrigerant. No. Tool name Specifications auge manifold Only for R07C. Use the existing fitting SPECIFICATIONS. (UNF7/) Use high-tension side pressure of.mpa or over. Charge hose Only for R07C. Use pressure performance of.0mpa or over. Electronic scale as leak detector Use the detector for Ra or R07C. Adapter for reverse flow check. Attach on vacuum pump. Refrigerant charge base. 7 Refrigerant cylinder. For R07C Top of cylinder (Brown) Cylinder with syphon 8 Refrigerant recovery equipment.

5 CAUTIONS RELATED TO NEW REFRIERANT Cautions for units utilising refrigerant R0A Use new refrigerant pipes. In case of using the existing pipes for R, be careful with the followings. For RP0/7VHA and RP00//0, be sure to perform replacement operation before 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 refrigerant piping is clean and it has no contamination such as sulfur hazardous for use, oxides, dirt, shaving particles, etc. In addition, use pipes with specified thickness. Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc. 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. Do not use refrigerant other than R0A. If other refrigerant (R etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc. 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 auge manifold Flare tool Charge hose Size adjustment gauge as leak detector Torque wrench 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. Vacuum pump adaptor Electronic refrigerant charging scale 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. [] 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. Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

6 Unit ravimeter [] Service tools Use the below service tools as exclusive tools for R0A refrigerant. No. auge manifold Only for R0A Charge hose Only for R0A Electronic scale Specifications Use the existing fitting specifications. (UNF/) Use high-tension side pressure of.mpa or over. Use pressure performance of.09mpa or over. as leak detector Use the detector for Ra, R07C or R0A. Adaptor for reverse flow check Attach on vacuum pump.
