    1Safety Precautions
    •Read the following  “SAF ETY PRECAUTIONS” ca refully before pe rform any servicing.
    •Electrical wo rk mu st be installed or serviced by a licensed elec trician. Be sure to use the correct rating of the po wer plug and
    main circuit for the model installed.
    •The caution items stated here must  be followed be cause these important  contents are rela ted to  safety. The me aning of each
    in
    d ication used is as be low. Incorrect installation  or servicing  due to igno ring of the instru ction will ca use harm or damage, and
    the
      seriou sness is classified  by the fo llow ing indications.
    •The items to be follo wed are classified by the symbo ls:
    • Carry out test running to  confirm that no ab normality occurs after the se rvicing. T hen, expla in to  user the op eration, care and
    mai
    nten ance as stated in instructions. Please  remind the customer  to ke ep the ope rating in structions for fu ture refere nce.
    This indication shows  the p ossibility  of causing death or serious injury.
    This
      indication shows  the p ossibility of causing  injury or  damage to pr operties.
    T his symbol denotes item  that  is PROHIBIT ED f rom doing.
    1. Engage dealer or sp ecialist for  installat ion  and  serv icing. If installat ion or  servicing  done by the us er is defective, it wi ll cause  water
    leakage, electrical shock o
    r  fire.
    2.Install  accord ing to this installation  instru ction strictly .  If installation  is defective,  it  will cause water leakage, electrical  shock or fir e. 
    3.Use the attac hed accessories parts  and s pecified parts for  instal lation and serv icing. Other wise,  it will cause the set to fall, w ater
    leakage, fire o
    r  electr ical shock.
    4.Install at a st rong and firm location which is  able to withstand t he set’s  weight. If the str ength is not  enough or installat ion is notproperly done, the  set will dr op and cause injury.
    5.F or electrical work,  follow the  local  nation al wiring standar d, re gulation and the installation  instruction. An  independent circuit and
    single
      outlet must be  used. If  electrical ci rcuit capacity is  not e nough or defec t found in electrical work,  it  will  cause  electr ical shock or
    fire.
    6.Use the  specified  cable  and conn ect tight ly for indoor/outdoor  connection. C onnect tightly  and c lamp the c able so that  no extern alfo rce will be  acted on the t erminal. If  conn ection or fixing is not per fect, it will  cause heat- up or  fire at  the connectio n.
    7. Wire routing must be pr oper ly arranged  so that control bo ard  cover is fixed pr operly. If  cont rol board cover  is not fixed per fectly, it  will
    cause
      heat- up or fire  at the connection point of terminal, fire or electrical  shock.
    8. When conne cting the piping,  do n ot allow  air or  any s ubstances ot her than  the  specified refrigerant to  enter the  refrigeration  cyc le.
    Ot he
    rwise, this may lower t he cap acity, cause abnorma lly high pr essure in  the refriger ation cycle, and p ossibly result in explosion and
    injury.
     9
    . It is desir able that the amount of  resid ual oil is less than 40 mg/10m.
    10.Do not  modify  the length  of the  power supply  cord or use of the  exte nsion cor d, and  do n ot share  the single outlet with  other electr ical
    ap pliances. Ot herwise, it  will cause fire or electrical shock.
    11
    .After  comple tion of the installation  serv icing confirm there is  no leak age of refr igerant  gas. It may generate toxic gas  when the
    refriger
    a nt contacts with  fire.
    12
    .V entilate if there is r efrigerant gas  leakage during operation. It  may cause  toxic gas when  the refr igerant contacts  with fir e.
    1.T he equipment  must be earthed. It  may cause el ectrical shock if  grounding is n ot perfect.
    2.Do  not install the  unit at place where leakage  of flammable gas may occur. In  case gas leaks and accum ulates at surround ing of the
    unit, it  may cause f ire.
    3.Carry out drainage piping  as me ntioned in  installa tion instructions.  If dr ainage is not perfect,  water  may enter the  room and damagethe furniture. 
    						
    							4
    4. Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use
    a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
    Pb free solder will tend to splash when heated too high (about 1100°F / 600°C).
    5. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
    may break and cause refrigerant gas leakage.
    6. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.
    AT T E N T I O N
    1. Selection of the installation location. Select an installation location which is rigid and strong enough to support or hold the unit, and select a
    location for easy maintenance.
    2. Power supply connection to the conditioner. Connect the power supply cord of the air conditioner to the mains using one of the following
    methods.
    Power supply point shall be the place where there is ease for ease for access for the power disconnection in case of emergency.
    In some countries, permanent connection of this room air conditioner to the power supply is prohibited.
    1. Power supply connection to the receptacle using a power plug. Use an approved power plug with earth pin for the connection to the
    socket.
    2. Power supply connection to a circuit breaker for the permanent connection. Use an approved circuit breaker for the permanent
    connection. It must be a double pole switch with a minimum 3.5 mm contact gap.
    3. Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigeration parts. Take care of
    the liquid refrigerant, it may cause frostbite.
    4. Installation work. It may need two people to carry out the installation work.
    5. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
