Page 4: Safety Precautions
1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before installation.  Electrical work must be installed 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 5 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 6 WARNING When Wiring ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.  Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. ...
Page 7 …In laundry rooms Do not install in laundry rooms. Indoor unit is not drip proof. When Connecting Refrigerant Tubing Pay particular attention to refrigerant leakages. WARNING  When performing piping work, do not mix air except for specified refrigerant in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high tension inside the refrigerant cycle.
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 The appliance shall be stored, installed and operated in a well ventilated room with indoor floor area larger than A ) [refer Table A] and without any continuously operating ignition source.
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 2-9. Checks to the refrigerating equipment  Where electrical components are being changed, they shall be fit for the purpose and to the correct specification.  At all times the manufacturer’s maintenance and service guidelines shall be followed.  If in doubt consult the manufacturer’s technical department for assistance.
Page 11 CAUTION Detection of flammable refrigerants  Under no circumstances shall potential sources of ignition be used in the searching or detection of refrigerant leaks.  A halide torch (or any other detector using a naked flame) shall not be used. ...
Page 12 CAUTION Decommissioning  Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.  It is recommended good practice that all refrigerants are recovered safely.  Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant.
