[. . . ] Attention must be paid to the rising up of drain hose Fix the unit to concrete or block with bolts (10mm) and nuts firmly and horizontally. When fitting the unit to wall The marks from A to G in the figure are the parts numbers. The distance between the indoor unit and the floor should be more than 2m. Surface, roof or rooftop, fix a supporter surely with nails or wires in consideration of earthquake and strong wind. [. . . ] Precautions for Handling Units for Use with R410A Caution Do not use the existing refrigerant piping Use a vacuum pump with a reverse-flow check valve. If other types of valves are used, the vacuum pump oil will The old refrigerant and refrigerator oil in the existing piping flow back into the refrigerant cycle and cause the refrigerator contain a large amount of chlorine, which will cause the oil to deteriorate. R410A is a high-pressure refrigerant, and the use of the Do not use the following tools that have been used with the existing piping may result in bursting. (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. 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. 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. 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. 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. Do not connect the grounding on the unit to gas pipes, water pipes, lightning rods, or the grounding terminals of telephones. Improper grounding presents a risk of electric shock, smoke, fire, or the noise caused by improper grounding may cause the unit to malfunction. do not spray water on the air conditioners or immerse the air conditioners in water. [. . . ] Using this table as a reference, choose pipes that meet the local standards. To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. If the pipe has to be lengthened, the refrigerant should be charged, according to E g/m. [. . . ]
