NETAFLEX™ 3G 

INSTALLATION MANUAL

INSTALLATION

Dual dosing channel

If the NetaFlex™ has more than 4 dosing channels (up to 6), the dual dosing channel option is utilized.

 Up to 2 dual dosing channels are installed on the NetaFlex™ 3G, at the farthest manifold positions

  (1 and 4).

 The dual dosing channel option is applicable with 600 l/hr (158 GPH) or 50 l/hr (13 GPH) Venturis.

CAUTION

There are fertilizer combinations that should never be used in 

the dual dosing channel as they will induce crystalization and 
cause clogging of the pipes.

 Calcium N Ammonium Sulfate => Calcium Sulfate

 Calcium N Potassium Sulfate => Calcium Sulfate

 MKP + Calcium Nitrate => Calcium Phosphate

 MAP + Calcium Nitrate => Calcium Phosphate

 Phosphoric acid + Calcium Nitrate => Calcium Phosphate

In case of doubt regarding the use of any combination of 
fertilizers in the dual dosing channel, consult your local 
Netafim™ representative.
