2.3.4 Drain water tanks
Drain water tanks are not part of the NoNa
+
itself. The NoNa
+
works with a minimum
of one and up to a maximum of eight drain water tanks. If you have one drain water
tank, the NoNa
+
is fitted with a manual inlet and outlet valve for the drain water. If
you have multiple drain water tanks, electric valves are used.
If you have more than one drain water tank, you will need an extra Smart
Switch (see "I/O modules" on the next page).
The NoNa
+
works with one drain water tank at a time. The water from this drain
water tank is purified in the NoNa
+
, and then the purified water is returned to the
same drain water tank. When this is done, the NoNa
+
starts on the next drain water
tank. The drain water tanks are treated sequentially.
Using the HortiMaX-Go!, you can set which drain water tank are used when and for
how long. For more information, see "Periods" on page 58 and "Drain water tank" on
page 58.
2.3.5 Pumps
The NoNa
+
uses two pumps:
Drain water pump
Wastewater pump
These pumps are of the same type.
The pump that has been selected depends on the capacity of the NoNa
+
, the electric
voltage and the frequency.
