  • Page 3: Safety Precaution

    SAFETY PRECAUTION 2-1. CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R410A Use a vacuum pump with a reverse flow check Use new refrigerant pipes. valve. Avoid using thin pipes. Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc.
  • Page 4 [1] Cautions for service (1) Perform service after recovering the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant.
  • Page 5 Cautions for refrigerant piping work New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working pressure of R410A is 1.6 times higher than that of R22, their sizes of flared sections and flare nuts are different.

Procedures of test run (1) Before a test run, make sure that the following work is completed. • Installation related : Make sure that the panel of cassette type and electrical wiring are done. Otherwise electrical functions like auto vane will not operate normally.
  • Page 41 9-1-2. Special Function Operation and Settings (for M-NET Remote Controller) • It is necessary to perform “group settings” and “paired settings” at making group settings of different refrigerant systems (multiple outdoor unit). (A) Group settings: Enter the indoor unit controlled by the remote controller, check the content of entries, and clear entries, etc.
  • Page 42 (2) Address check: Refer to section (1) regarding address entry. a) In making group settings: • Turn off the remote controller: Press the remote controller's ON/OFF button to stop operation (the indicator light will go off). • Locate the indoor unit address display mode: Press the FILTER and k buttons on the remote controller simultaneously and hold for 2 seconds.
  • Page 43 9-1-3. Countermeasures for Error During Test Run • If a problems occurs during test run, a code number will appear in the temperature display area on the remote controller (or LED on the out- door unit), and the air conditioning system will automatically cease operating. Determine the nature of the abnormality and apply corrective measures.
