Provide a suitable air baffle. a snowy area (for heat pump systems) Install the outdoor unit on a raised platform higher than the accumulated snow. Offer snowy places. When connecting refrigerant pipes • Keep all pipes as short as possible. • Use the flaring method to connect the pipe. • Apply cutting fluid to the contact surfaces of the flare and connection tubes before connecting them, and then tighten the nut with a torque wrench to achieve a leak-free connection. • Check carefully for leaks before starting the test. NOTE: Depending on the type of system, the liquid and gas lines can be narrow or wide. Therefore, to avoid confusion, the refrigerant tube for your specific model is specified as "small" or "large" rather than "liquid" or "gas." During maintenance • Turn off the power at the main switch before opening the unit to check or repair electrical parts and wiring. • Keep fingers and clothing away from moving parts. • Clean the site once you are done and remember to check that no metal or wire is left on the serviceable unit. • After installation, explain the correct operation to the customer using the operating instructions. This air conditioner uses the new HFC refrigerant (R410A). 5 cm or more The basic installation procedures are the same as for models with conventional refrigerant (R22). However, pay close attention to the following points: (1) Since the working pressure is 1.6 times the working pressure of conventional refrigerant (R22) models, some of the piping and installation and maintenance tools they are special. (See table below.) Especially when replacing a conventional refrigerant (R22) model with a new R410A refrigerant model, always replace conventional pipes and flare nuts with R410A pipes and flare nuts. (2) Models with R410A refrigerant have a different charging port thread diameter to prevent incorrect charging with conventional refrigerant (R22) and for safety reasons. So check beforehand. [The thread diameter of the charging port for R410A is 1/2 thread per inch.] (3) Prevent foreign matter (oil, water, etc.) from entering the pipe better than refrigerant (R22) models. . Also, when storing the hoses, close the opening securely by squeezing, closing, etc. (4) When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the liquid phase side. whose composition is stable. Special tools for R410A Tool name Gauge manifold Charging hose Vacuum pump Gas leak detector Copper pipes Change content The pressure is high and cannot be measured with a conventional pressure gauge. To avoid incorrect mixing of other refrigerants, the diameter of each connection has been changed. Gauges with -0.1 to 5.3 MPa (-1 to 53 bar) seals are recommended for high pressure. -0.1 to 3.8 MPa (-1 to 38 bar) for low pressure. The hose material and base size have been changed to increase resistance to pressure. A conventional vacuum pump can be used by installing a vacuum pump adapter. Special gas leak detector for HFC R410A refrigerant. It is necessary to use seamless copper pipes, and it is desirable that the amount of residual oil is less than 40mg/10m. Do not use copper tubing with collapsed, deformed, or discolored parts (particularly on the inner surface). Otherwise, the expansion valve or capillary tube may be clogged with impurities. Since an air conditioner with R410A creates a higher pressure than when using R22, it is necessary to select suitable materials. Table 1 Thickness of Annealed Copper Tubing Thickness (mm) Nominal Diameter The thickness of copper tubing used with R410A is listed in Table 1. Never use copper tubing less than 0.8mm thick, even if it is available on the market. WARNING 1/4 1/2 Outside diameter (mm) 6.35 12.7 R410A 0.80 0.80 [ref.] R22 (1) Do not use existing piping (for R22) or flare nuts. • If existing materials are used, the pressure in the refrigerant cycle will increase, causing rupture, injury, etc. (Use special materials R410A). (2) When installing and relocating the air conditioner, do not mix gases other than those specified. refrigerant (R410A) to enter the refrigerant cycle. • If air or other gas enters the refrigeration cycle, the pressure in the cycle will rise to an abnormally high level, causing rupture, injury, etc. CAUTION By installing pipes shorter than 3 m, the noise from the outdoor unit will be reduced. to the indoor unit, causing a large operating noise or abnormal noise. 0.80 0.80
