Warning: Use the specified cables for wiring. Make the connections securely so that the outside force of the cable is not applied to the terminals. - Inadequate connection and fastening may generate heat and cause a fire. Have all electric work done by a licensed electrician according to Electric Facility Engineering Standard and Interior Wire Regulations and the instructions given in this manual and always use a special circuit. - If the power source capacity is inadequate or electric work is performed improperly, electric shock and fire may result. Securely install the cover of control box and the panel. - If the cover and panel are not installed properly, dust or water may enter the outdoor unit and fire or electric shock may result. After completing service work, make sure that refrigerant gas is not leaking. - If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or other heat source, it may generate noxious gases. Do not reconstruct or change the settings of the protection devices. - If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result.

4 PRECAUTIONS FOR DEVICES THAT USE R0C REFRIGERANT Caution Do not use the existing refrigerant piping. The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the refrigerator oil of the new unit to deteriorate. Use refrigerant piping made of phosphorus deoxidized copper and copper alloy seamless pipes and tubes. In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant. Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate. Store the piping to be used during installation indoors and keep both ends of the piping 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 oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections. The refrigerator oil will degrade if it is mixed with a large amount of mineral oil. 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 a vacuum pump with a reverse flow check valve. The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate. Do not use the following tools that have been used with conventional refrigerants. (Gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, refrigerant recovery equipment) If the conventional refrigerant and refrigerator oil are mixed in the R0C, the refrigerant may deteriorated. If water is mixed in the R0C, the refrigerator oil may deteriorate. Since R0C does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it. Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate. Be especially careful when managing the tools. If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate. If the refrigerant leaks, recover the refrigerant in the refrigerant cycle, then recharge the cycle with the specified amount of the liquid refrigerant indicated on the air conditioner. Since R0C is a nonazeotropic refrigerant, if additionally charged when the refrigerant leaked, the composition of the refrigerant in the refrigerant cycle will change and result in a drop in performance or abnormal stopping. Do not use a refrigerant other than R0C. If another refrigerant (R, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.

5 [] Storage of Piping Material () Storage location Store the pipes to be used indoors. (Warehouse at site or owner s warehouse) Storing them outdoors may cause dirt, waste, or water to infiltrate. () Pipe sealing before storage Both ends of the pipes should be sealed until immediately before brazing. Wrap elbows and T s in plastic bags for storage. * The new refrigerator oil is 0 times more hygroscopic than the conventional refrigerator oil (such as Suniso). Water infiltration in the refrigerant circuit may deteriorate the oil or cause a compressor failure. Piping materials must be stored with more care than with the conventional refrigerant pipes.

6 [] Piping Machining Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections. Use only the necessary minimum quantity of oil! Reason :. The refrigerator oil used for the equipment is highly hygroscopic and may introduce water inside. Notes : Introducing a great quantity of mineral oil into the refrigerant circuit may also cause a compressor failure. Do not use oils other than ester oil, ether oil or alkylbenzene.

7 [] Necessary Apparatus and Materials and Notes on Their Handling The following tools should be marked as dedicated tools for R0C. <<Comparison of apparatus and materials used for R0C and for R>> Apparatus Used Use R R0C Gauge manifold Evacuating, refrigerant filling Current product Charging hose Operation check Current product Charging cylinder Refrigerant charging Current product Do not use. Gas leakage detector Gas leakage check Current product Shared with Ra Refrigerant collector Refrigerant collection R For R0C use only Refrigerant cylinder Refrigerant filling R Identification of dedicated use for R0C : Record refrigerant name and put brown belt on upper part of cylinder. Vacuum pump Vacuum drying Current product Vacuum pump with a check valve Current product Flare tool Flaring of pipes Current product Bender Bending of pipes Current product Application oil Applied to flared parts Current product Torque wrench Tightening of flare nuts Current product Pipe cutter Cutting of pipes Current product Welder and nitrogen cylinder Welding of pipes Current product Refrigerant charging meter Refrigerant charging Current product Vacuum gauge Checking the vacuum degree Current product Can be used by attaching an adapter with a check valve. Ester oil or Ether oil or Alkybenzene (Small amount) Symbols : To be used for R0C only. Can also be used for conventional refrigerants. Tools for R0C must be handled with more care than those for conventional refrigerants. They must not come into contact with any water or dirt. 6

8 [] Brazing No changes from the conventional method, but special care is required so that foreign matter (ie. oxide scale, water, dirt, etc.) does not enter the refrigerant circuit. Example : Inner state of brazed section When non-oxide brazing was not used When non-oxide brazing was used Items to be strictly observed :. Do not conduct refrigerant piping work outdoors on a rainy day.. Apply non-oxide brazing.. Use a brazing material (Bcup-) which requires no flux when brazing between copper pipes or between a copper pipe and copper coupling.. If installed refrigerant pipes are not immediately connected to the equipment, then braze and seal both ends of them. Reasons :. The new refrigerant oil is 0 times more hygroscopic than the conventional oil. The probability of a machine failure if water infiltrates is higher than with conventional refrigerant oil.. A flux generally contains chlorine. A residual flux in the refrigerant circuit may generate sludge. Note : Commercially available antioxidants may have adverse effects on the equipment due to its residue, etc. When applying non-oxide brazing, use nitrogen.

9 [] Airtightness Test No changes from the conventional method. Note that a refrigerant leakage detector for R cannot detect R0C leakage. Halide torch R leakage detector Items to be strictly observed :. Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment s airtightness, taking temperature variations into account.. When investigating leakage locations using a refrigerant, be sure to use R0C.. Ensure that R0C is in a liquid state when charging. Reasons :. Use of oxygen as the pressurized gas may cause an explosion.. Charging with R0C gas will lead the composition of the remaining refrigerant in the cylinder to change and this refrigerant can then not be used. Note : A leakage detector for R0C is sold commercially and it should be purchased. [6] Vacuuming. Vacuum pump with check valve A vacuum pump with a check valve is required to prevent the vacuum pump oil from flowing back into the refrigerant circuit when the vacuum pump power is turned off (power failure). It is also possible to attach a check valve to the actual vacuum pump afterwards.. Standard degree of vacuum for the vacuum pump Use a pump which reaches 0. Torr (00 MICRON) or below after minutes of operation. In addition, be sure to use a vacuum pump that has been properly maintained and oiled using the specified oil. If the vacuum pump is not properly maintained, the degree of vacuum may be too low.. Required accuracy of the vacuum gauge Use a vacuum gauge that can measure up to Torr. Do not use a general gauge manifold since it cannot measure a vacuum of Torr.. Evacuating time Evacuate the equipment for hour after mmhg ( Torr) has been reached. After envacuating, leave the equipment for hour and make sure the that vacuum is not lost.. Operating procedure when the vacuum pump is stopped In order to prevent a backflow of the vacuum pump oil, open the relief valve on the vacuum pump side or loosen the charge hose to drawn in air before stopping operation. The same operating procedure should be used when using a vacuum pump with a check valve. 8

10 [] Charging of Refrigerant R0C must be in a liquid state when charging, because it is a non-azeotropic refrigerant. For a cylinder with a syphon attached For a cylinder without a syphon attached Cylinder Cylinder Cylinder color identification R0C-Gray Charged with liquid refrigerant R0A-Pink Valve Valve Liquid Liquid Reasons :. R0C is a mixture of refrigerants, each with a different evaporation temperature. Therefore, if the equipment is charged with R0C gas, then the refrigerant whose evaporation temperature is closest to the outside temperature is charged first while the rest of refrigerants remain in the cylinder. Note : In the case of a cylinder with a syphon, liquid R0C is charged without turning the cylinder up side down. Check the type of cylinder before charging. [8] Dryer. Replace the dryer when the refrigerant circuit is opened (Ex. Change the compressor, full gas leakage). Be sure to replace the dryer with a CITY MULTI Series Y (For use with R0C). If any other product is used, the unit will be damaged.. Opening the refrigerant circuit after changing to a new dryer is less than hour. The replacement of the dryer should be the last operation performed. 9
