FIRST FILLING OF THE PROCESS TANK
T
he definition “first
filling
”
refers to any time the process tank must be filled with the conditioning solution (i.e. also
after commissioning and servicing). The further refills must be done using demineralized water only.
For a first fill follow the steps below:
1.
Prepare th
e solution as described in the previous paragraph (“
Preparation of the Conditioning Solution
or
use the solution included in the shipment.
2.
In a separate container, prepare a 2 litres of DI water, this is used to top up the solution in case more water
is needed to fill the system to the appropriate level.
3.
Insert one end of the rigid tubing into the water refilling port (
W1.2
) and the other end into the external
vessel. Notice: the pump draws up to 1 meter in height, keep the solution elevated so that filling is performed
faster.
4.
Plug the power cable into the EL2.0. Press the start/stop button and continue to apply pressure to it. Start
supplying power to the EL2.0. Continue to hold the start/stop button down.
5.
The refilling pump will start drawing the solution and it will automatically fill the internal water tank. When
the water starts being pumped into the module you can release the start/stop button. The process will stop
automatically when the water reaches maximum level.
FURTHER REFILLS
Since the electrolytic process consumes only water, only a first fill with the conditioning solution is required. The
further fills must be done using demineralized water only.
The refilling of the process tank in the EL2.0 module from an external water tank starts automatically and is
independent from the hydrogen production. The pump starts drawing as soon as the water level sensor indicates
that the solution has reached the medium level.
An alarm appears in case the liquid contained in the process tank has reached the minimum level: this normally
means that the external water tank is empty, and the user has to refill it with demineralized water up to maximum
level in order to restore conditions without shutting down and re-starting the device.
WARNING:
Dried out cells will cause damage, which is not covered by warranty.
WARNING!
It is the responsibility of the user to ensure that after system draining, the module is refilled using the
specified solution.
WARNING:
Ensure that the refilling water pressure never exceeds 4 bar!
WARNING:
Do not repeatedly reset the device (by switching on/off) because the pump will start drawing
immediately and may overheat.
