[. . . ] This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Refrigerant type:R410A GWP* value:1975 GWP=global warming potential Please fill in with indelible ink, · The filled out label must be adhered in the proximity of the product charging port (e. Onto the inside of the stop value cover). A contains fluorinated greenhouse gases covered by the Kyoto Protocol B factory refrigerant charge of the product: see unit name plate C additional refrigerant amount charged in the field D total refrigerant charge E outdoor unit F refrigerant cylinder and manifold for charging For installation of the indoor units, refer to the installation manual which was provided with the units. [. . . ] Prepare tools that are for exclusive use with R410A. (Gauge manifold , charging hose , gas leak detector , reverse-flow check valve , refrigerant charge base , vacuum gauge , and refrigerant recovery equipment. ) If refrigerant and/or refrigerant oil left on these tools are Keep the inner and outer surfaces of the pipes clean and mixed in with R410, or if water is mixed with R410A, it will free of contaminants such as sulfur, oxides, dust/dirt shaving cause the refrigerant to deteriorate. Contaminants inside the refrigerant piping will cause the Since R410A does not contain chlorine, gas-leak detectors for conventional refrigerators will not work. Caution Store the piping to be used during installation indoors, and Do not use a charging cylinder. Keep both ends of the piping sealed until immediately before The use of charging cylinder will change the composition brazing. (keep elbows and other joints wrapped in plastic. ) of the refrigerant and lead to power loss. If dust, dirt, or water enters the refrigerant cycle, it may cause the oil in the unit to deteriorate or may cause the compressor to malfunction. Exercise special care when handling the tools. An introduction of foreign objects such as dust, dirt or Use a small amount of ester oil, ether oil, or alkylbenzene water into the refrigerant cycle will cause the refrigerating to coat flares and flange connections. A large amount of mineral oil will cause the refrigerating machine oil to deteriorate. use liquid refrigerant to charge the system. Charge the unit with gas refrigerant will cause the refrigerant Only use R410A refrigerant. In the cylinder to change its composition and will lead to The use of refrigerants containing chlorine(i. Caution Do not install the unit in a place where there is a possibility When installing the unit in a hospital, take necessary measures of flammable gas leak. Leaked gas accumulated around the unit may start a fire. High-frequency medical equipment may interfere with the normal operation of the air conditioning unit or the air Do not use the unit to preserve food, animals, plants, artifacts, conditioning unit may interfere with the normal operation or for other special purposes. Of the medical equipment The unit is not designed to provide adepuate conditions to preserve the quality of these items. Do not use the unit in an unusual environment The use of the unit in the presence of a large amount of oil, steam, acid, alkaline solvents or special types of sprays Do not place the unit on or over things that may not get wet. May lead to a remarkable drop in performance and/or When humidity level exceeds 80% or when the drainage malfunction and presents a risk of electric shock, smoke, system is clogged, indoor units may drip water. Installation of a centralized drainage system for the outdoor The presence of organic solvents, corroded gas (such as ammonia, sulfur compounds, and acid may cause gas or unit may also need to be considered to prevent water drips water leak. [. . . ] the connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Be careful that matters, such as wastes of sands, water, etc. If the pipe has to be lengthened, the refrigerant should be charged, according to E g/m. [. . . ]
