Page 5: Safety Precautions
1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.  Confirm the type of gas used before installation.  Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model to be installed.
Page 6 WARNING  For R32/R410A model, use piping, flare nut and tools which is specified for R32/R410A refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury. For R32 and R410A, the same flare nut on the outdoor unit side and pipe can be used.
Page 7 CAUTION Select an installation location which is easy for maintenance. Incorrect installation, service or repair of this air conditioner may increase the risk of rupture and this may result in loss damage or injury and/or property. Power supply connection to the room air conditioner. Use power supply cord 3 x 1.5 mm²...
Page 8: Precaution For Using R32 Refrigerant
2. Precaution for Using R32 Refrigerant  Pay careful attention to the following precaution points and the installation work procedures: WARNING When connecting flare at indoor side, make sure that the flare connection is used only once, if torqued up and released, the flare must be remade.
Page 9 CAUTION General  Must ensure the installation of pipe-work shall be kept to a minimum. Avoid use dented pipe and do not allow acute bending.  Must ensure that pipe-work shall be protected from physical damage.  Must comply with national gas regulations, state municipal rules and legislation. Notify relevant authorities in accordance with all applicable regulations.
Page 10 CAUTION 2-10. Checks to electrical devices  Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures.  Initial safety checks shall include but not limit to:- That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking. That there is no live electrical components and wiring are exposed while charging, recovering or purging the system.
Page 11 CAUTION Charging procedures  In addition to conventional charging procedures, the following requirements shall be followed. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. Cylinders shall be kept in an appropriate position according to the instructions.

Page 83: Installation And Servicing Air Conditioner Using R32
13. Installation and Servicing Air Conditioner using R32 13.1 About R32 Refrigerant For air conditioning refrigerants such as R410A, the refrigerants were collected back in order to prevent their air dissipation, to curbe the global warming impact, in case they were released into the atmosphere. In the “4th Environmental Basic Plan”, 80% reduction of greenhouse gas emissions by 2050 is required, and due to this requirement, further reduction in the emission of high greenhouse effect gas, such as CFCs, is required.
Page 84 2. Characteristic of Pressure As shown in Table 2, R32 does not have much difference in vapor pressure at the same refrigerant temperature comparing to R410A, but comparing to R22, it is higher at 1.6 times more. Thus, the same as in case of R410A, it is necessary to do installation and service using high-pressure tools and components.
