An anti-siphon
An anti-siphon
· The anti-siphon device needs to be installed in
the fish tank. There is no difference in direction
between the two small heads on the device, but
the large head needs to be higher than the water
surface and lower than the edge of the glass. .
· If the water level in the bucket is higher
than the water level in the area where
the main controller is installed, an
anti-siphon device should also be installed
above the pump in the bucket.
· An anti-siphon device must be installed
above the drainage pump, otherwise non-
stop drainage may occur;
An anti-siphon · If it is not in the process of changing water, such
as when the circulating pump is stopped, at this
time,if the water level is higher than the siphon
prevention device, no siphon phenomenon will
occur.
Installation of
the host
· The main control has a water level detection
device, so the main control needs to be installed
in the transparent glass to work properly;
Please check the connection method：
Appendix 1: Sea water,water source are buckets
Appendix 2: Seawater, A.T.O. source is water purifier

steps
2. Connect the water inlet device to the green
connector and the drain pump to the black
connector;Connect the temperature probe to
the black audio connector.
1. Install the host on the section where the
water level in the fish tank can change, and
make the current water level near the "LOW"
water level line.
· You can use a PE pipe(DN10)(commonly used
for RO water purifiers) to extend the water
inlet and outlet pipes, and you can directly put
the hose on a rigid pipe (at least 5cm is
appropriate).
4. Fill the bucket with water.
3. Install anti-siphon device and water pipe
according to the figure.
1. Turn on the power, and then press the three
buttons at the same time. After 5 seconds, the
system will emit a beep sound. At this time, you
can release the buttons.

· The installation site must be cleaned before
installation. Large algae or dirt may cause
abnormal sensing.
· Please note that the internal and external
modules must be aligned, otherwise they cannot
be sensed normally.

· Back filter is usually opaque. After cutting the
black opaque film on the glass with a knife, the
device can be used normally.

Water pipe
· The water outlet of the water inlet pipe must be
higher than the water surface, otherwise the
water in the fish tank may flow back to the
bucket.

Precautions
· AWC introduction: Automatic replacement of
old and new water for the fish tank according to
the specified water exchange volume and · If
you do not specify an automatic water change
cycle, you can only start a water change task by
manually clicking the AWC button.
· If the water level drops quickly after
exceeding the HIGH level line, there may be
water droplets remaining on the sensor
head, which may cause a false alarm that the
water level is too high. You can take out the
internal module and shake it gently to
remove the water droplets.
· One-key top-up: If the water level is lower
than the LOW level when the A.T.O.
function is paused, short press the A.T.O.
button to start one-key top-up.
· If you do not specify an automatic water change
cycle, you can only start a water change task by
manually clicking the AWC button.
· Clicking any button during the water change will
stop the water change.

· The significance of automatic calibration:
Because the size of the fish tank is different for
each user, the calibration function allows the
equipment to scan and calculate the fish tank in
order to accurately provide automatic water

· If you choose the simultaneous water inlet
and outlet mode, the water change will not end
immediately when the water change amount
reaches the predetermined value. The system
will automatically adjust the water level to the
middle of the MID and LOW sensing points, and
then return to the standby interface.

· During calibration, as long as the inlet and outlet
pumps are working properly and the water level is
not lower than the low induction line or higher
than the high induction line, it is normal.
· The larger the fish tank, the closer the speed of
water entering and exiting, the longer it takes,
even more than half an hour.
· When the water level is too high (higher than HIG),
or low (below Low), the water change cannot be
started.
The amount of water used in the water level
adjustment and pump check process is not included
in the total water exchange volumeexchange.

· After the water change is started, the water
will be automatically drained below the LOW
sensor line, and then a small amount of water
will be introduced until the water level is
normal. This process is used to determine that
the water inlet and outlet channels are normal.

* Please install the water inlet and outlet pipes according to the direction
of the water flow indicated by the arrow on the side of the solenoid valve.
Incorrect installation of the water inlet and outlet pipes will cause the

· If the compression sponge comes into contact with a small amount of
water, the switch above will be lifted by the expansion, and the water
