In order to make the product monitoring more accurate and avoid errors, please clean the fish tank wall where the monitor is placed and the two sides where the monitor is fixed on the fish tank wall during the first use. And it is recommended to clean regularly.

Put the monitor into the tank and outside the tank respectively, move them horizontally until they are overlapped, and never overlap the inner and outer parts directly. Because the magnetic force in hygger product is very strong.

Make sure that there are no obvious bubbles in the fish tank water near where the monitor is placed.

It will affect the judgment of the sensor and cause incorrect or non-refilling of water.

• When the water level line is near A (the first monitoring probe), the product will automatically refill water;
• When the water level reaches B (the second monitoring probe), the automatic refill will be suspended;
• Our product uses an ultra-wide prism, and point C will always be kept clean. When the point below B is covered with impurities for a long time, the monitoring fails and overflows, but C is not affected, and an alarm will sound.

Put the holder on the wall of the fish tank;

Tighten the screws to fix;

Align the clip with the protruding slide, and install the hose clip;

Insert the hose;

Install the last hose clamp.

If the external sensor is placed in a spare water tank with glass, please slide the installation horizontally. The thickness of the glass wall of the fish tank is recommended to be ≤0.15in.

If you are using a bucket and the thickness is very thick, you can put all the external sensors in the bucket instead of placing them separately.

The small black button is to prevent water from entering the hole, so please save it when not in use.
