  • Page 3: Safety Precautions

    1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.  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 installed. ...
  • Page 4 WARNING 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. For electrical work, follow the wiring rules AS/NZS 3000, national regulation, legistration and this installation instructions. An independent circuit and single outlet must be used.
  • Page 5 CAUTION Installation or servicing work: It may need two people to carry out the installation or servicing work. Pb free solder has a higher melting point than standard solder; typically the melting point is 50°F – 70°F (30°C – 40°C) higher. Please use a high temperature solder iron.

  • Page 6: Precaution For Using R32 Refrigerant

    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 7 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 8 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. (Detection equipment shall be calibrated in a refrigerant-free area.)  Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. ...
  • Page 9 CAUTION Labelling  Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant.  The label shall be dated and signed.  Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant. Recovery ...

    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.

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.
