  • Page 2: Important

    IMPORTANT! This symbol refers to a hazard or WARNING Please Read Before Starting unsafe practice which can result in severe personal injury or death. This air conditioner must be installed by the sales dealer This symbol refers to a hazard or or installer.
  • Page 3 • Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. • Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
  • Page 4 …In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors. CAUTION Keep the fire alarm and the air outlet at least 1.5 m away from the unit. …In Moist or Uneven Locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit.
  • Page 5 • Electronic leak detectors may be used to detect refrigerant leaks but, the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) • Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used.
  • Page 6 CAUTION • Ventilate any enclosed areas when installing or testing the refrigeration system. Leaked refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. • Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source, it can cause the generation toxic gas and fire.
  • Page 7 SERVICING CAUTION • Any qualified person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from an industry-accredited assessment authority, which authorizes their competence to handle refrigerants safely in accordance with an industry recognised assessment specification. •...
  • Page 8 Marking to the equipment continues to be visible and legible. Markings and signs • that are illegible shall be corrected. Refrigerating pipe or components are installed in a position where they are • unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
  • Page 9 REMOVAL AND EVACUATION CAUTION • When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to: Remove refrigerant.
  • Page 10 Recovery equipment and cylinders conform to the appropriate standards. • d) Pump down refrigerant system, if possible. e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f) Make sure that cylinder is situated on the scales before recovery takes place. g) Start the recovery machine and operate in accordance with instructions.

  • Page 11: Check Of Density Limit

    Check of Density Limit Check the amount of refrigerant in the system and floor space of the room according to the legislation on refrigerant drainage. If there is no applicable legislation, follow the standards described below. The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the requirements for the maximum refrigerant charge amount [m ] used in the appliance are determined according to installation space of the appliance.
  • Page 12 < Whether or not to use R32 refrigerant leakage detection sensor > • According to the type of diagrams shown in Fig. 2, it is necessary to install R32 refrigerant leakage detection sensor if the installation space is within the range of using R32 refrigerant leakage detection sensor.
