9-3. HOW TO OPERATE FIXED-FREQUENCY OPERATION <Test run operation>
1. Press the emergency operation switch to start COOL or HEAT mode (COOL : Press once, HEAT : Press twice).
2. Test run operation starts and continues to operate for 30 minutes.
3. Compressor operates at rated frequency.
4. Indoor fan operates at High speed.
5. After 30 minutes, test run operation finishes and EMERGENCY OPERATION starts (Operation frequency of compressor
varies).
6. To cancel test run operation or EMERGENCY OPERATION, press the emergency operation switch or any button on
remote controller.
9-4. OUTDOOR LOW PRESSURE AND OUTDOOR UNIT CURRENT CURVE
(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 units are under the
same temperature/humidity condition.
Operation : TEST RUN OPERATION (Refer to 9-3.)
