(S/W version up) 2 SAFETY PRECAUTION CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R407C Do not use the existing refrigerant piping. Do not use a refrigerant other than R407C. The old refrigerant and lubricant in the existing piping contain a large amount of chlorine which may cause the lubricant deterioration of the new unit. If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration. 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 indoors, and both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.) 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 enters, that can cause deterioration of refrigerant oil etc. Use liquid refrigerant to charge the system. 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. Use the specified refrigerant only. Never use any refrigerant other than that specified. Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of. Correct refrigerant is specified in the manuals and on the spec labels provided with our products. We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to follow the instructions. Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop. OCH447B 2 [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 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. Tool name Specifications 1 Gauge manifold 2 Charge hose 3 Electronic scale · Only for R407C · Use the existing fitting SPECIFICATIONS. (UNF7/16) · Use high-tension side pressure of 3.43MPa·G or over. · Only for R407C · Use pressure performance of 5.10MPa·G or over. — 4 Gas leak detector · Use the detector for R134a or R407C. 5 Adaptor for reverse flow check · Attach on vacuum pump. 6 Refrigerant charge base 7 Refrigerant cylinder 8 Refrigerant recovery equipment — · For R407C · Top of cylinder (Brown) · Cylinder with syphon OCH447B 3 — Cautions for units utilizing refrigerant R410A 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 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 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. Tools for R410A Flare tool Size adjustment gauge Vacuum pump adaptor Electronic refrigerant charging scale Handle tools with care. Store the piping indoors, and both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.) If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor. If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor. Do not use a charging cylinder. The refrigerant oil applied to flare and flange connections must be ester oil, ether oil or alkylbenzene oil in a small amount. If large amount of mineral oil enters, 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 R410A. If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc. If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered. Use the specified refrigerant only. Never use any refrigerant other than that specified. Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of. Correct refrigerant is specified in the manuals and on the spec labels provided with our products. We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to follow the instructions. Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. 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. OCH447B 4 [1] Cautions for service (1) Perform service after recovering 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.) Unit Gravimeter [3] Service tools Use the below service tools as exclusive tools for R410A refrigerant. No. 1 Tool name Gauge manifold Specifications · 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 3 Electronic scale 4 Gas leak detector · Use the detector for R134a, R407C or R410A. 5 Adaptor for reverse flow check · Attach on vacuum pump. 6 Refrigerant charge base 7 Refrigerant cylinder 8 Refrigerant recovery equipment · Use pressure performance of 5.09MPa·G or over. — — · Only for R410A · Top of cylinder (Pink) · Cylinder with syphon OCH447B — 5 3 PART NAMES AND FUNCTIONS 3-1.
