    PRECAUTIONS 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 for both the indoor and outdoor units to the OFF position. Otherwise, electric shocks may result.
  • Page 10 WARNING Before starting to repair the air conditioner, read carefully through the Service Manual, and repair the air conditioner by following its instructions. Only qualified service person (*1) is allowed to repair the air conditioner. Repair of the air conditioner by unqualified person may give rise to a fire, electric shocks, injury, water leaks and / or other problems.
  • Page 11 If, in the course of carrying out repairs, it becomes absolutely necessary to check out the electrical parts with the electrical parts box cover of one or more of the indoor units and the service panel of the outdoor unit removed in order to find out exactly where the trouble lies, put a sign in place so that no- Do not bring one will approach the work location before proceeding with the work.
  • Page 12 When the refrigerant gas leaks during work, execute ventilation. If the refrigerant gas touches to a fire, poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.
  • Page 13 Only a qualified installer (*1) or qualified service person (*1) is allowed to install the air conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or vibration may result. Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install the air conditioner.

  • Page 26: Refrigerant (R410A)

    Refrigerant (R410A) This air conditioner adopts a HFC type refrigerant (R410A) which does not deplete the ozone layer. 1. Safety Caution Concerned to refrigerant (R410A) The pressure of R410A 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 27 4. Tools (1) Required Tools for R410A 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 R410A (Those which cannot be used for conventional refrigerant (R22)) 2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22) 3) Tools commonly used for R410A and for conventional refrigerant (R22) The table below shows the tools exclusive for R410A and their interchangeability.
