  • Page 4 WARNING Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or electrical shock. Install at a strong and firm location which is able to withstand weight of the set. If the strength is not enough or installation is not properly done, the set will drop and cause injury.
  • Page 5 2. Precaution for Using R32 Refrigerant  The basic installation work procedures are the same as conventional refrigerant (R410A, R22) models. However, pay careful attention to the following points: WARNING Since the working pressure is higher than that of refrigerant R22 models, some of the piping and installation and service tools are special.
  • Page 6 CAUTION 2-5. No ignition sources  No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. He/She must not be smoking when carrying out such work.
  • Page 7 CAUTION Leak detection methods  Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re- calibration.

  • Page 54 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 55 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.
