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.
