    8. FUNCTION 8-1. Room Temperature Control Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.

  • Page 30: Dry Operation

    8-2. Dry Operation (Dehumidification) Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.

    10. REFRIGERANT R410A : SPECIAL PRECAUTIONS WHEN SERVICING UNIT 10-1. Characteristics of new refrigerant R410A 10-1-1. What is new refrigerant R410A R410A is a new refrigerant that contains three types of non-azeotropy-type mixed refrigerant. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant R22.
  • Page 42 Tubing precautions Refrigerant R410A is more easily affected by dust or moisture compared with R22, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation. Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners with R410A are subject to higher pressure than those using R22 and R407C.
