And the LED will display "P1" while the water full lamp flashes at 2Hz. 2. 2. 4. 4. 4 When the water adds up to the second position on the chassis and the switch has been on for 10 seconds, the whole unit will stop operation. The LED will display "P2" and the water full lamp will flash at 5Hz. After you have clear the problem, you should unplug the unit and plug again. 2. 2. 4. 4. 5 When the unit is standing by, if the unit displays "P1", the pump will not operate. After the problem is cleared, the unit will be ready to operate. But if you push the power button, the unit will shut the "P1" display and shut down. 2. 2. 5 Fan-only Mode Function Requirement 2. 2. 5. 1 The compressor and outdoor fan are OFF at Fan-only mode. 2. 2. 5. 2 The speed of indoor fan can be optionally chosen as High/Mid/Low. 2. 2. 6 Cooling Mode Function Requirement 4 2. 2. 6. 1 The speed of indoor fan can be optionally selected as High/Mid/Low. Replace the transformer if either of the input/output is open or the transformer is damaged. Replace the display board if it is +5V else replace the main PCB. Replace batteries if the voltage is lower than 2. 3V. Call an electrician if not within limits. Test capacitor. No power display on panel or any one of the buttons failure. Display board or main PCB Remote control failure. failure Battery failure Transformer (Discharge transformer before testing) Fan motor runs intermittently Replace if not within +/-10% of manufacture's rating. Replace the motor if the blower wheel cannot rotate freely. Pay attention to any change from high speed to low speed. Replace the motor if the speed does not change. The amount of the refrigerant is too much, making the Compressor stops instantly after startup. Refrigerant compressor load too big.
