Warning
Work on electrical equipment may only be carried out by qualified personnel. The controller and USB-C power supply are not suitable for outdoor use. Mount the controller in a dry location protected from excessive moisture, wetness and direct sunlight. The controller must not be installed in the cistern dome or submerged.

Required tools

Drill
with a 5 mm drill bit for the wall plugs

Cordless screwdriver
with a PZ2 bit
Mounting location
- The mounting surface must be flat, dry and load-bearing.
- The power supply and sensor cable must be reachable.
- Check with a mobile device whether the Wi-Fi signal is sufficient.
Mounting and connection
Attach the mounting plate
Hold the mounting plate against the wall, mark the screw positions and drill the holes with a 5 mm drill bit. Insert the wall plugs and secure the mounting plate with the screws.

Secure the sensor box in the cistern dome
Secure the sensor box using the included moulded part in the cistern dome. Align it so that the sensor hangs straight down.
Danger
Never immerse the black sensor box at the upper end of the sensor in water. It is protected against moisture, but it is not waterproof.
Warning
Do not cut or shorten the sensor. Coil any excess sensor cable and secure it neatly.
Caution
Leave the sensor capsule hanging at least 5 cm above the tank floor so that it does not rest in sediment or other contamination.

Route and connect the sensor cable
Route the sensor cable from the WaterGuard Level Controller to the tank opening. Do not kink, pinch or put the cable under tension. Plug the data cable into the designated socket and secure it with the union nut.


Close the housing
Insert the supplied silicone seals into all occupied and unused housing cutouts. Insert the back plate and close the housing with the four socket head screws using a 2.5 mm hex key.


Attach the controller and connect power
Place the WaterGuard Level onto the top of the mounting plate and slide it down until it sits securely. Then connect the USB-C power supply. The controller starts up.
