varies).
6. To cancel test run operation (EMERGENCY OPERATION), press EMERGENCY OPERATION switch or any button on
remote controller.
10-4. OUTDOOR LOW PRESSURE AND OUTDOOR UNIT CURRENT (single operation)
NOTE: The unit of pressure has been changed to MPa on the international system of units (SI unit system).
The conversion factor is : 1 (MPa[Gauge]) = 10.2(kgf/cm
(1) COOL operation
Both indoor and outdoor unit are under the
same temperature/humidity condition.
