1. Application
The water refilling system is used to automatically maintain
the nominal electrolyte levels.
The charging gasses escape through the vent on each cell.
NO WATERING IN THE FIRST 10 CYCLES.
2. Function
A valve and a float together control the topping up process
and maintain the correct water level in each cell. The valve
allows the flow of water into each cell and the float closes the
valve when the correct water level has been reached.
For fault-free operation of the water refilling system, please
note the instructions below:
2.1 Manual or automatic connection
The battery should be topped up shortly before completion
of a full charge, as at this point the battery has reached a
defined operational state resulting in satisfactory electrolyte
circulation. Filling takes place when the connector (7) from
the tank is connected to the coupling (6) on the battery.
Manual or automatic coupling has to be done in the intervals
according point 7. (see point 7.)
2.2 Filling time
Filling time depends on the utilisation rate and the
corresponding battery temperature. Generally speaking, the
top up process takes a few minutes and can vary according to
the battery range; after this, if manual filling is being used, the
water supply to the battery should be turned off.
2.3 Working pressure
The water refilling system should be installed in such a way
that a water pressure of 0.2 to 0.6 bar is obtained (with at
least 2 m height difference between the upper edge of the
battery and the lower edge of the tank). Any deviation from
this means that the system will not function properly.
2.4 Purity
The topping up water must be purified. The water used to
refill the batteries must have a conductance of not more
than 30 µS/ cm. The tank and pipes must be cleaned before
operating the system.
2.5 Pipe system on the battery
The pipe system to the individual battery cells must follow
the battery’s electrical circuit. This reduces the risk of
current leakage in the presence of electrolytic gas causing
an explosion (EN 62485-3). A maximum of 18 cells may be
connected in a series.
The system should not be modified in any way.
2.6 Working temperature
In winter, batteries fitted with Aqualevel should only be
charged or refilled in a room temperature above 0 °C.
2.7 Flow control
A flow indicator built into the water supply pipe to the battery
monitors the filling process. During filling the water flow
causes the built-in disc in the flow indicator to turn. When all
the plugs are closed the disc stops, indicating that the filling
process is complete.
6. Malfunctions
If malfunctions are found on the battery or the charger, our
service department should be called in without delay. The
measurements taken in point 3.3 will facilitate fault finding
and their elimination.
A service contract with us will make it easier to detect and
correct faults in good time.
