  • Page 23: Current Control

    7-2-2. Current Control The operating current may rise as a result of causes including increasing heating or cooling loads or decreases in power voltage. In these cases, the operating frequency is automatically reduced, or operation is stopped, in order to control the operating current so that it is (19.5 A) or less.
  • Page 24 7-2-3. Low Start Current Operation starts at (8 Hz), and the start current is less than the normal operating current. This prevents the flickering of fluorescent lights or television screens that occurs when ordinary A/C units start. 7-2-4. Compressor Temperature Control To protect the compressor coil from overheating, the operating frequency is controlled based on the compressor discharge temperature.

Noise Reducing Control (Outdoor Unit) The noise reducing control is the function used for silent operation of the air conditioner by means of setting the dip switch on the outdoor unit P.C.Board to control the fan and compressor's motor speed. NOTE When this function is used, the cooling or heating ability is slightly degraded.
  • Page 26 7-3-2. Maximum Current Value Change Function The maximum current value is changed to 15.0A or 13.5A to prevent power breaker tripping. (It is set to 20A when the unit is delivered from the factory.) NOTE 1. When the high load is given (Outside temperature is high in the cooling operation, or outdoor temperature is low in the heating operation), the capacity is reduced.

Be sure to pay attention to the following before inspecting or repairing the outdoor- side electronic circuits. High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 311 V) even after the power is turned OFF, and some time is required for the charge to dissipate.

    9. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT 9-1. Characteristics of New Refrigerant R410A 9-1-1. What is New Refrigerant R410A? R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22. 9-1-2.
  • Page 36 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.
