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

    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 mildly 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 After repair work, surely assemble the disassembled parts, and connect and lead the removed wires as before. Perform the work so that the cabinet or panel does not catch the inner wires. If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is caused at user fs side.
  • Page 11 When the service panel of the outdoor unit is to be opened in order for the compressor or the area around this part to be repaired immediately after the air conditioner has been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the service panel.
  • Page 12 CAUTION Ensure wearing of gloves when performing any work in order to avoid injury from parts, etc. Failure to wear the proper protective gloves cause an injury due to the parts, etc. Wearing of gloves When performing the brazing work, check whether refrigerant leaks or remains. If the leakage refrigerant gas touches a fire source, it may generate noxious gases, causing a fire.
  • Page 13 APPENDIX Minimum floor area: Amin (m When an outdoor unit using R32 refrigerant is combined with this indoor unit, do not install the indoor unit in a poorly ventilated space that is smaller than the minimum floor area (Amin). For refrigerant quantity, refer to Fluorinated Greenhouse Gases label on the outdoor unit. For the minimum floor area (Amin) of this indoor unit, refer to table below.

  • Page 16: About Refrigerant R32

    About refrigerant R32 This air conditioner adopts a new HFC type refrigerant (R32) which does not deplete the ozone layer. 1. Safety Caution Concerned to Refrigerant R32 Be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the refrigerating cycle of the air conditioner with refrigerant R32 during installation work or service work.
  • Page 17 <Caution items> 1) The opposite side dimension of the air-conditioner’s flared nut using R32 and the shape of the charge port are the same as those of R410A. 2) Be careful not to charge refrigerant by mistake. Should the different type of refrigerant be mixed, be sure to recharge the refrigerant.

  • Page 19: About Refrigerant R410A

    About refrigerant R410A This air conditioner adopts a HFC type refrigerant (R410A) which does not deplete the ozone layer. 1. Safety Caution Concerned to R410A Refrigerant The pressure of R410A is 1.6 times higher than that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed.
  • Page 20 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.
