    Isn't it warming up? page 9 When the air conditioner does not operate properly after you have checked the above mentioned items or when the following phenomenon is observed, stop the operation of the air conditioner and contact your sales dealer.
  • Page 9 Water or steam generates from the outdoor unit during heating. When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a trouble.
  • Page 10: Care And Maintenance

    Operate the unit with FAN mode on a fair day for about half a day to dry the inside of the unit well. Stop operation and turn off the power supply switch. Electric power is consumed even the air conditioner is in stop.
  • Page 11: For Preparation Of Heating

    Defrosting operation When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat ex- changer of outdoor unit along with the drop of indoor temperature. Since the accumulated frost re- duces the effect of warming, it is necessery to automatically switch the operation to the defrosting mode.

    Besides, construction expense is charged for removal or reinstallation. The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about three years although depending upon the circumstances under which it is used, and so in addition to the usual maintenance service, special inspection/maintenance service is necessary.

    INSTALLATION MANUAL FOR OUTDOOR UNIT Selection of installation site It should be installed at places where it is firm enough to withstand the weight of the air conditioner to prevent falling. Typhoon and earthquake prevention. It should be installed according to specific requirements.
  • Page 24 INSTALLATION MANUAL FOR OUTDOOR UNIT Refer to the following figure for the distance between the foundation bolts. (2)When the refrigerant pipe is connected from the bottom of the unit,the unit should be raised at least 500mm(see the figure below) (3)In snowy regions,snow-proof facilities should be used(see the figure below).
