with water supply electrical conductivity. The lower the electrical conductivity,
the longer it takes the water to boil.)
2. Press the
humidier 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
humidier cylinder decreases. Water is drained
smoothly, and the pipe is free from leakage.
3. Switch the plug screw, as shown in Figure 5-7, until water ows out of the
plug screw.

4. If the condensate pump does not react during the water charging or drainage,
you can recharge and drain the pump to make the low oat oating for a
period of time. After the condensate pump is started, check that the pump
drains properly and the pipe is free from leakage.
If the condensate pump does not react, you can directly charge the water tank
with water to ensure that the condensate pump can start and operate; If self-
drainage is connected or slow water charging speed occurs, the condensate pump
may not react, which requires water keeping on charging.
Step 7 Go outside to verify 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:
● Whether the light of the phase sequence protector is on. If it is
o, the phase
sequence may be incorrect or the indoor unit signal cable is improperly
connected. You can rectify the fault by referring to the outdoor unit user
manual.
● Whether the signal cable for the indoor and outdoor units is properly
connected.
