➢Can I fix the tube holder on a rimmed tank/sump?
Yes. You can pull out the ring of the tube holder and install
it on another nail to fix it on a rimmed tank/sump.

➢How to install the prefilter properly?
First, please connect the prefilter base to the prefilter.
Then, install the prefilter before the diaphragm pump (Inlet
Tube 1, 3, and 5 ) to protect it from clogged and damaged.
Note : please clean it every 3 to 6 months for the best
filtration performance.

➢Where should I place the Lifter Pump Holder?
We suggest to place Lifter Pump Holder at the waste water
reservoir, where the tube might be drift in the water.

➢Where should I place the sensor?
Place the sensor to the water level you desired.
*Please note : Set the sensor away from water outlet and direct
light to avoid bubble interference or malfunctions.

➢What is the Anti-Siphon Pressure Height?
There will be forward siphon when pump stops if the inlet tank
of water level is higher than the outlet tube.
To avoid forward siphon, the outlet tube must less than 1-ft
(30cm) below the water level of inlet tank.
Outlet must ALWAYS be out of water.
If you desired higher anti-siphon pressure height, you can buy
AUTOAQUA Anti-Siphon Valve. One anti-siphon valve can stop
about 60cm of water of the forward siphon pressure.

➢What is AWC Balance Mode?
After P3 pumps the new water in the tank, there will be a “AWC
Balance Mode” for 3 minutes with faded green AWC mode
(Manual/ 4H/ 12H/ 24H/ 48H) indicator.
Therefore, in balance mode, it will fill new water automatically
if the water level is lower than the sensor.
The final water level will be more accurate.
Water level might get down when refill water distributed goes
through the whole tank.

➢What is the benefit of using Diaphragm Pump?
⚫Add water smooth & consistent flow to reach the
desired water level accurately.
⚫Lessen the pressure to aquarium ecosystem.
⚫No wire in the tank for tidy aquarium.
⚫Able to run dry without damage for safety aquarium.

➢How to replace diaphragm pump?
⚫Step 1 : Press the release button on
the side and open the top
cover.
⚫Step 2 : Disassemble the PCB screw and the pump wire.
Then, remove the PCB and take the diaphragm
pump out.
⚫Step 3 : Place the new diaphragm
pump back in and
assemble pump wire, PCB,
and PCB screw back.
⚫Step 4 : Put the sensor wires in
the correct position.
⚫Step 5 : Make sure the springs are all
in the correct position before
close the cover.
⚫Step 6 : Plug the power in, reset the device, and test all the
buttons function. If the button works improperly,
please open the cover and adjust the
spring to the accurate position.

➢Why does the water keep dripping after pump has
stopped?
The forward siphon pressure is too high.
Please lower the water level in the corresponding reservoir, or
adjust the outlet tube higher.
If neither is an option, you can purchase AUTOAQUA Anti-
Siphon Valve(s) and connect it to the outlet tube(s).
One anti-siphon valve can stop about 60cm of water of the
forward siphon pressure.
*Connect three or more anti-siphon valve will prevent the
pump from working properly.

➢Why is the water level always little higher/lower than
the sensor?

➢Why does Smart AWC Lite power on for only a short
while and give an audible alert?
QST is not set correctly.
Please reset Smart AWC Lite according to the reset procedure
in user manual, p10.
Next, mount the blue sensor at the normal water level (with
lower sensor indicating the water level) before connecting the
power and do not move it afterwards. If you want to move the
sensor or change the water level, you have to reset Smart
AWC Lite and unplug and plug it back in again.

➢Why the pump stops with beeping alarm and orange
light but the water level hasn’t reach the sensor?
It is QST function.
For ATO, QST will alarm as water refill time is 6 times longer
than the first refill time.
For AWC, QST will alarm as water change time is 3 times
longer than the first water change time.
If you would like to increase the QST tolerance, please clear
QST memory and extend the first time ATO refill time or AWC
water change time.

➢Can Smart AWC Lite detect empty reservoir?
Yes.
With AUTOAQUA Quick Security Technology (QST), it can
detect empty reservoir without extra sensor.
If there is too little or no water in reservoir, it will trigger QST.
The system will shut itself off and stop the pump.

➢What can QST do for you?
With AUTOAQUA QST function, it can detect below scenario
sensorless and without extra setting.
⚫Empty Reservoir Detection
If there is too little or no water in reservoir, it will trigger QST.
The system will shut itself off and stop the pump.
⚫Pump Failure
When pump fails, causing no water replenishment, the QST
will alarm as ATO is 6 times longer than the first time/ AWC is
3 times longer than the first time.
⚫Sensor Failure
If both normal and fail-safe sensor fail, it will trigger QST and
shut itself off.
⚫Others Device Failure
If above 3 scenario have been excluded, it might be other
device failure ( ex. Return pump, Skimmer…etc.). Please
check others device in your aquarium system.
