  • Page 4 Definition of Protective Gear When the air conditioner is to be transported, installed, maintained, repaired or removed, wear protective gloves and ‘safety’ work clothing. In addition to such normal protective gear, wear the protective gear described below when undertaking the special work detailed in the table below.

  • Page 6 Precaution for Safety The manufacturer shall not assume any liability for the damage caused by not observing the description of this manual. DANGER Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker to the OFF position. Otherwise, electric shocks may result. Before opening the electrical control box cover of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the OFF position.
  • Page 7 Electrical wiring work shall be conducted according to law and regulation in the community and Installation manual. Failure to do so may result in electrocution or short circuit. To connect the electrical wires, repair the electrical parts or undertake other electrical jobs, wear gloves to provide protection for electricians, insulating shoes and clothing to provide protection from electric shocks.
  • Page 8 Connect the cut-off lead wires with crimp contact, etc, put the closed end side upward and then apply a water-cut method, otherwise a leak or production of fire is caused at the users' side. Insulating measures When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that coats the pipes may otherwise burn.
  • Page 9 When the refrigerant gas leaks, find up the leaked position and repair it surely. If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room. The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.
  • Page 10 Only a qualified installer or service person is allowed to do installation work. Inappropriate installation may result in water leakage, electric shock or fire. Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install the air conditioner. If the unit is installed in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit concentration even if it leaks.

  • Page 16 • Refrigerant (R32) This air conditioner adopts a refrigerant HFC (R32) which does not deplete the ozone layer. 1. Safety Caution Concerned to Refrigerant R32 The pressure of R32 is high 1.6 times of that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed.
  • Page 17 4. Tools 1. Required Tools for R32 Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary, etc. Accordingly, the tools to be used are classified into the following three types. 1) Tools exclusive for R32 (Those which cannot be used for conventional refrigerant (R22)) 2) Tools exclusive for R32 but can be also used for conventional refrigerant (R22) 3) Tools commonly used for R32 and for conventional refrigerant (R22) The table below shows the tools exclusive for R32 and their interchangeability.
