2 Optimization
2.1 Howtooptimizewaterowformorethan5mhead.
For more than 5m head, adjust the air regulator screw on the pump body. See chapter
3.2.3.1 (Pg. 7, in this manual).
3 Troubleshooting
3.1 MKII system problems
3.1.1 Power button does not light up
Problem: After connecting to solar panel with sucient sunlight and main switch is
turn on, Power button does not light up.
Check:
1 Make sure solar panel cable is connected to the PMB.
2 Make sure solar panel surface is not cover by any obstacles, even a thin grass on the
surface will aect performance of solar panel.

Doc number: 002 Revision: PA3
3 If power button still not light up. Let solar panel charge PMB for at least 1hour then
try again. Charge with power button (K) OFF and Main switch (N) ON.
4 If after charging and under strong sunlight (>750W/m2), power button still does not
light up, consult your local service center.
3.1.2 PMB stop once or repeated times
Problem: PMB run for a short while and stop
Check:
1 Make sure solar panel is not covered by any obstacles and facing towards sun.
2 This may due to battery pack power is completely at. Charge for 1hour and try
again. Charge with power button (K) OFF and Main switch (N) ON.
3 If after charging and under strong sunlight (>750W/m2), power button still does not

3.2 Operation Problems
3.2.1 Reducedwaterow
Problem: Water volume owing out the water extraction tube is signicantly reduced.
Check:
1 Make sure pump unit is 30cm below
water surface..
2 Make sure Ø8mm air hose is not bent.
3 Make sure there are no air and water
leakage from all connectors.
• Check for Air: Air outlet from back
of PMB, Ø8mm air hose connector,
Ø16mm air tube connector.
• Check for Water: Ø25mm water tube connector. If needed, the Ø25mm water tube
connector need to be uninstalled and installed again to make sure all tightness are
done properly. Check step by step installation of the Ø25mm water tube connector
referring in the MKII system installation manual chapter 7.3.2 (Pg. 13).

3.2.3 Wrong water level in pressure vessel after connecting to the drip line for
one growing area.
Problem: Water level in the pressure vessel (C) is not at the OK mark.
Check: Acceptable range is between MIN and MAX mark. If water level is below MIN
or above MAX follow instruction below.
3.2.3.1 Adjust air regulator screw
1 Turn OFF the PMB power button and
then main switch to stop the system.
