    • The qualified service person is a person who installs, repairs, maintains, relocates and removes the air conditioners made by Toshiba Carrier Corporation. He or she has been trained to install, repair, maintain, relocate and remove the air conditioners made by Toshiba Carrier Corporation...
  • 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 5 Warning Indications on the Air Conditioner Unit [Confirmation of warning label on the main unit] Confirm that labels are indicated on the specified positions If removing the label during parts replace, stick it as the original. WARNING WARNING ELECTRICAL SHOCK HAZARD ELECTRICAL SHOCK HAZARD Disconnect all remote Disconnect all remote electric power supplies before servicing.
  • Page 6 Precaution for Safety The appliance shall be installed in accordance with national wiring regulations. Capacity shortages of the power circuit or an incomplete installation may cause an electric shock or fire. DANGER Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker to the OFF position.
  • Page 7 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 8 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, wear insulated heat-resistant gloves, insulated boots and insulated work overalls, and take care to avoid touching any live parts.
  • Page 9 This Air Conditioner has adopted a refrigerant HFC R32 or R410A. Be sure to check the refrigerant type for outdoor unit to be combined. In case that refrigerant type is R32, this unit uses a flammable refrigerant. If refrigerant leaks and comes in contact with fire or heating part, it will create harmful gas and there is risk of fire.
  • Page 10 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. When gas touches to fire such as fan heater, stove or cocking stove, it may generate noxious gases, causing a fire though the refrigerant gas itself is innocuous.
  • Page 11 ∗ ∗ 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.
