6. Adjust the humidifier and condensate pump.
a. After the humidifier is started, the water supply solenoid valve leads to a higher liquid level
in the humidifier. Make sure that water supply is smooth and the water pipe is free from
leakage. Water inside the humidifier is with bubbles or boils after 10 minutes.
b. Press the humidifier manual drainage switch on the electric control box side panel, and
ensure that the water drainage solenoid valve generates a bang. The water level in the
humidifier decreases. Water is drained smoothly, and the pipe is free from leakage.
c. Switch the plug screw to discharge air, until water flows out of the plug screw.
d. If the condensate pump does not react, you can recharge and drain to make the low float
floating for a period of time. After the condensate pump is started, check that the pump
drains properly and the pipe is free from leakage.
7. Ensure that the rotation direction of the outdoor fan is consistent with that shown on the label,
and the outdoor fan rotates smoothly. If the outdoor fan does not rotate, check that:
a. Whether the light of the phase sequence protector is on. If it is off, the phase sequence
may be incorrect or the indoor unit signal cables are improperly connected.
b. Signal cables for the indoor and outdoor units are properly connected.
8. Adjust the compressor and humidifier input into 0 rpm and 0%. Exit the diagnostic mode.
9. Record parameter values during the commissioning. For details, see the Power-On
