Injection and intermixture device [ 24 ]
Caution!
Don´t install the injection valve direct into a metal tube. The chlorine dioxide will destroy the tube
by corrosion in a short time. Select one of the following devices for the installation into metal pipe-
works:
•
Injection and intermixture device type „DMU“ [ 24 ]
•
Injection lance made of PVDF like type „LINI-K“ (Option) as
Take care that the dosing hose [ B ] is protected against direct sunshine. The sun radiation de-
grades the chlorine dioxide back into its basic chemicals. Use a suitable protection hose (Option).
Multifunction valve
Warning:
•
Don´t remove the multifunction valve!
•
The counter-pressure in the dosing line must be minimum 1 bar at any time!
•
With the yellow knob you can adjust the counter-pressure
between 1 – 5 bar depending to the actual installation situation.
•
The overpressure and priming hose is laid to the dilution water
storage tank. In case of an overpressure the chlorine dioxide
flows into the tank and will be diluted. From there it overflows into the drain.
Dilution water connection [ A ]
Inside LOTUS is a storage tank [ 8 ] for the dilution water. The automatic refill is controlled by a float valve [ 9 ].
The float valve has to be connected to the water line with a 4x6 mm PE-hose (2 m included in the delivery
scope).
Notice:
•
In case the pressure in the water line is more than 5 bar a pressure regulator valve in the re-
filling line is required. The adjusting range should be 0.3 – 4 bar.
•
For a proper function of the pressure regulator valve and the float valve inside the tank a pro-
tection filter like a ”
NFIL/60“ is recommended.
Overflow connection [ C ] for the dilution water storage tank
The dilution water storage tank [ 8 ] has a overflow connection with a 20 mm PVC adhesive connection.
The overflow should be connected to a floor drain.
Overpressure and priming hose
Multifunction valve type „MFKT“
