PUMP SAFEGUARDS
To prevent damage to the pump, the NoNa
+
will stop and generate an alarm
message if:
the pump is overheating.
The pumps are fitted with a temperature sensor. This sensor generates an
alarm if the water around the pump gets too hot.
Consult the pump's manual to check its direction of rotation and bleed
air from the pump.

Testing the NoNa
+
To test the NoNa
+
, you can switch the NoNa
+
on briefly. Before doing this, check the
following:
1. Is the NoNa
+
drawing drain water from the drain water tank and is the purified
drain water being pumped back into the drain water tank?
2. Is wastewater being pumped into and out of the wastewater tank?
3. Is the fresh water tank being filled?
4. Are the wastewater and drain water pumps operating without excessive noise?
5. Is acid being dosed during the short flush with fresh water?
6. Is sodium being removed during purification?
A laboratory can perform tests to check that at least 20% of sodium is
being removed. For this, you need to take samples of the drain water
and send them to the laboratory for analysis. Complete the following
steps to take samples:
Let the NoNa
+
run for at least 10 minutes.
Take samples. Before and after the stack, there are points where
you can take samples.
Label the samples.
Send the samples to the laboratory for mineral or nutrient
analysis.
7. Is acid being dosed during intermittent (acid) cleaning?
8. Is the electric current and voltage (in the stack) being measured?
9. Does the flow rate correspond to the value in the table below? To check the flow
rate, navigate this path:
.
10. Is the EC value before the stack higher than the EC value after the stack?
11. Are there any alarm messages?
