5.2 Startup:
When the power is switched on, the screen will fully light up for 3 seconds, the device code will be
displayed, and then it will enter the normal working state. When the screen is locked, only the button
will light up; Press and hold for more than 3 seconds to unlock the screen. The screen will
automatically lock up when there is no operation for more than 1 minute and the brightness of the screen
will be reduced to 1/3 of the normal display. Short press to wake up the screen and observe the
relevant operating parameters.
5.3 Self-priming
When switched on for the first time after installation, the pump will start self-priming.
When the pump performs self-priming, it will count down from 1500s and stop automatically when the
system detects the pump is full of water, then the system will recheck for 30s again to make sure the
self-priming is completed.
User can exit self-priming manually by pressing for more than 3 seconds. The pump will enter the
default Manual-Inverter mode at the initial startup. If the user exits the self-priming in the subsequent
startup, the pump will return to the previous state before the last shutdown.
Remark:
The pump is delivered with self-priming enabled. Each time the pump restarts, it will perform self-priming
automatically. User can enter the parameter setting to disable the default self-priming function (see 5.10)
If the default self-priming function is disabled, and the pump has not been used for a long time, the water
level in the strainer basket may drop. User can manually activate the self-priming function by pressing
both for 3 seconds, the adjustable period is from 600s to 1500s (default value is 600s). After
the manual self-priming is completed, the pump will return to the previous state before activating the
manual self-priming. If the pump has entered the Auto-Inverter mode previously, the pump will perform
self-learning for 180s to redefine the adjustable flow range after the manual self-priming.
User can press for more than 3 seconds to exit the manual self-priming, and the pump will run the
same as the manual self-priming is completed.
