INTRODUCTION
In most aquarium systems the loss of water from the aquarium is mainly due to factors such as evaporation. If
evaporated water is not regularly replaced, problems can occur and the water quality of the aquarium may be
compromised. The Auto Top Up Compact System provides a simple and hassle-free solution to automatically top up
any water lost from the aquarium or sump through evaporation and to create an advanced professional set-up.
PARTS REQUIRED FOR INSTALLATION AND OPERATION
1. Residual current device (RCD) with a rated residual operating current not exceeding 30mA.
ASSEMBLY
The Auto Top-up IR System is supplied almost fully
assembled. After unpacking and before installation you must:-
1. Ensure that the IR sensor guard is correctly secured on
the mounting bracket (see photo 1).
2. Connect components to the control unit (see photo 2 & 3).
3. Connect the black cable (IR water level monitoring sensor)
into the "Water Level Sensor" port.
4. Connect the white cable (IR water level monitoring safety
sensor) into the "Safety Sensor" port. (only on x 2 model)
5. Connect the pump to the "Pump" port.
Please Note: Always leave a drip-loop in all cables to
prevent water running down the cables and reaching the
control unit and power source.
6. Carefully cut the flexible top up hosing and install the
anti-siphon valve (see diagram below).
