AIR CONDITIONER 2011 Service Handbook Model PURY-RP200, RP250, RP300YJM-B
Safety Precautions Before installing the unit, thoroughly read the following safety precautions. Observe these safety precautions for your safety. WARNING This symbol is intended to alert the user to the presence of important instructions that must be followed to avoid the risk of serious injury or death. CAUTION This symbol is intended to alert the user to the presence of important instructions that must be followed to avoid the risk of serious injury or damage to the unit.
WARNING Securely attach the terminal block cover (panel) to the unit. After completing the service work, check for a gas leak. If the terminal block cover (panel) is not installed properly, dust and/or water may infiltrate and pose a risk of electric shock, smoke, and/or fire. If leaked refrigerant is exposed to a heat source, such as a fan heater, stove, or electric grill, poisonous gases may be produced.
Precautions for handling units for use with R410A CAUTION 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 and the end faces of the existing and new pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant. Prepare tools for exclusive use with R410A.
Before installing the unit WARNING Do not install the unit where a gas leak may occur. When installing the unit in a hospital, take appropriate measures to reduce noise interference. If gaseous refrigerant leaks and piles up around the unit, it may be ignited. High-frequency medical equipment may interfere with the normal operation of the air conditioner or vice versa. Do not use the unit to keep food items, animals, plants, artifacts, or for other special purposes.
Before installing the unit (moving and reinstalling the unit) and performing electrical work CAUTION Properly ground the unit. Periodically check the installation base for damage. Do not connect the grounding wire to a gas pipe, water pipe, lightning rod, or grounding wire from a telephone pole. Improper grounding may result in electric shock, smoke, fire, and/or malfunction due to noise interference. If the unit is left on a damaged platform, it may fall and cause injury.
Before the test run CAUTION Turn on the unit at least 12 hours before the test run. Do not operate the unit without panels and safety guards. Keep the unit turned on throughout the season. If the unit is turned off in the middle of a season, it may result in malfunctions. Rotating, high-temperature, or high-voltage parts on the unit pose a risk of burns and/or electric shock. To avoid the risk of electric shock or malfunction of the unit, do not operate switches with wet hands.

[ I Read Before Servicing ] [1] Read Before Servicing I Read Before Servicing 1. Check the type of refrigerant used in the system to be serviced. Refrigerant Type Multi air conditioner for building application REPLACE MULTI YJM-B series R410A 2. Check the symptoms exhibited by the unit to be serviced. Refer to this service handbook for symptoms relating to the refrigerant cycle. 3. Thoroughly read the safety precautions at the beginning of this manual. 4.
[ I Read Before Servicing ] [2] Necessary Tools and Materials Prepare the following tools and materials necessary for installing and servicing the unit. Tools for use with R410A (Adaptability of tools that are for use with R22 or R407C) 1. To be used exclusively with R410A (not to be used if used with R22 or R407C) Tools/Materials Use Notes Gauge Manifold Evacuation and refrigerant charging Higher than 5.
[ I Read Before Servicing ] [3] Storage of Piping 1. Storage location Store the piping materials indoors until they are ready to be installed (e.g., storage room on site or at the installer's premise). If left outdoors, dust, dirt, or moisture may infiltrate and contaminate the pipe, resulting in malfunctions. 2. Sealing the pipe ends Both ends of the pipes should be sealed until just before brazing. Keep elbows and T-joints wrapped in plastic bags to keep dust, dirt, and moisture out.
[ I Read Before Servicing ] [5] Brazing No changes have been made in the brazing procedures. Perform brazing with special care to keep foreign objects (such as oxide scale, water, and dust) out of the refrigerant system. Example: Inside the brazed connection Use of oxidized solder for brazing Use of non-oxidized solder for brazing 1. Items to be strictly observed Do not conduct refrigerant piping work outdoors if raining. Use non-oxidized solder.
[ I Read Before Servicing ] [6] Air Tightness Test No changes have been made in the detection method. Note that a refrigerant leak detector for R22 will not detect an R410A leak. Halide torch R22 leakage detector 1. Items to be strictly observed Pressurize the system with nitrogen to the design pressure (REPLACE MULTI Y(PUHY-RP): 3.3 MPa [479 psi]; REPLACE MULTI R2 (PURY-RP): 3.6 MPa [523 psi]), and check for refrigerant leakage. Take the temperature fluctuations into account when measuring pressure.
[ I Read Before Servicing ] [7] Vacuum Drying (Evacuation) (Photo1) 15010H (Photo2) 14010 Recommended vacuum gauge: ROBINAIR 14010 Thermistor Vacuum Gauge 1. Vacuum pump with a reverse-flow check valve (Photo1) To prevent the vacuum pump oil from flowing into the refrigerant circuit during power OFF or power failure, use a vacuum pump with a reverse-flow check valve. A reverse-flow check valve may also be added to the vacuum pump currently in use. 2.
[ I Read Before Servicing ] 7. Notes To evacuate air from the entire system Applying a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1 and 2) is not enough to attain the desired vacuum pressure. Be sure to apply a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1 and 2) and also through the check joints on the high and low pressure sides (CJ1 and 2).
[ I Read Before Servicing ] [8] Refrigerant Charging Cylinder without a siphon Cylinder with a siphon Cylinder Cylinder Cylinder color R410A is pink. Refrigerant charging in the liquid state Valve Valve liquid liquid 1. Reasons R410A is a pseudo-azeotropic HFC blend (boiling point R32=-52°C[-62°F], R125=-49°C[-52°F]) and can almost be handled the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder in the liquid phase.
[ I Read Before Servicing ] [10] Characteristics of the Conventional and the New Refrigerants 1. Chemical property As with R22, the new refrigerant (R410A) is low in toxicity and chemically stable nonflammable refrigerant. However, because the specific gravity of vapor refrigerant is greater than that of air, leaked refrigerant in a closed room will accumulate at the bottom of the room and may cause hypoxia. If exposed to an open flame, refrigerant will generate poisonous gases.
[ I Read Before Servicing ] [11] Notes on Refrigerating Machine Oil 1. Refrigerating machine oil in the HFC refrigerant system HFC type refrigerants use a refrigerating machine oil different from that used in the R22 system. Note that the ester oil used in the system has properties that are different from commercially available ester oil. Refrigerant Refrigerating machine oil R22 Mineral oil R407C Ester oil R410A Ester oil 2.

[ II Restrictions ] [8] Restrictions on Pipe Length 1. Determining the reusability of the existing piping Mitsubishi Electric Corporation cannot be held responsibility for the problems arising from the use of the existing pipes. Before installing the new air conditioning system, the existing piping system must be checked for refrigerant gas leaks, strength (material/thickness), and for corrosion.
[ II Restrictions ] CAUTION Charge refrigerant in the liquid state. If gaseous refrigerant is drawn out of the cylinder first, the composition of the refrigerant in the cylinder will change and become unsuitable for use. It will also lead to performance loss. CAUTION Store the piping materials indoors, and keep both ends of the pipes sealed until immediately before brazing. (Keep elbows and other joints in plastic bags.
[ II Restrictions ] Determining the reusability of the existing piping Start Do you know what kind of refrigerant oil is used in the existing system? YES NO Exisiting piping cannot be reused. Use new piping. NO Please contact your local distributor. Are the existing pipes still connected with indoor units and the outdoor units? (excluding sealed branch pipes that are not in use) NO If the piping is left disconnected, there is a possibility of contamination and corrosion inside the pipe.
