Use liquid refrigerant to charge the system. 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. 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” Do not use a refrigerant other than R407C. If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricant will result. If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration. 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 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. 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. 2 OC335--1.qxp 05.8.5 5:05 PM Page 3 [1] 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. [2] Refrigerant recharging (1) Refrigerant recharging process 1Direct charging from the cylinder. ·R407C cylinder are available on the market has a syphon pipe. ·Leave the syphon pipe cylinder standing and recharge it. (By liquid refrigerant) Unit Gravimeter (2) 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. [3] Service tools Use the below service tools as exclusive tools for R407C refrigerant. No. 1 Tool name Specifications Gauge manifold ·Only for R407C. ·Use the existing fitting SPECIFICATIONS. (UNF7/16) ·Use high-tension side pressure of 3.43MPa·G or over. 2 Charge hose ·Only for R407C. ·Use pressure performance of 5.10MPa·G or over. 3 Electronic scale 4 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 syphon 8 Refrigerant recovery equipment. 3 OC335--1.qxp 05.8.5 5:05 PM Page 4 CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilising refrigerant R410A Use new refrigerant pipes. Do not use refrigerant other than R410A. In case of using the existing pipes for R22, be careful with the followings. · For RP100, 125 and 140, 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. If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc. 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. 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 R410A refrigerant. The following tools are necessary to use R410A refrigerant. Gauge manifold Charge hose Gas leak detector Torque wrench Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc. Tools for R410A Flare tool Size adjustment gauge Vacuum pump adaptor Electronic refrigerant charging scale 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.) 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. 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. 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. If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered. [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 charge When 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.) 4 OC335--1.qxp 05.8.5 5:05 PM Page 5 Unit Gravimeter [3] Service tools Use the below service tools as exclusive tools for R410A refrigerant.
