WALL-MOUNTED Inverter Heat Pump/Powerful Heating Heat Pump
HOW TO OPERATE FIXED-FREQUENCY OPERATION
<Test run operation>
1. Press EMERGENCY OPERATION switch to 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 in COOL mode or 58Hz in HEAT mode.
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 (EMERGENCY OPERATION), press EMERGENCY OPERATION switch or any button on
remote controller.
OUTDOOR LOW PRESSURE AND OUTDOOR UNIT CURRENT
COOL operation
Both indoor and outdoor unit are under the same
temperature/humidity condition.

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
