Before using for the first time or after long pauses (e.g. holidays) the
machine may be difficult to pump water, this short procedure can help
pump to self priming by using the pipe to fill water into the circuit
manually prior to turn on the machine for first refill.
After above steps, the machine will be able to pump water out normally.
* If necessary, repeat the steps for 2 or 3 times.
Step 1# :
insert the pipe into the water entrance.
Step 2# :
fill water into the pipe.
Step 3# :
