NutriJet Bypass: EC control is unstable
SolutionPossible cause
Priva Partner: ensure a turbulent flow in the main line
by:
The supply water does not mix well with the water in
the main line.
• placing injection tubes in the inlet and outlet of the
supply line. This is only possible if the distance
between the connections of the supply line and the
return line in the main line is at least 1.5 m (see
Wateraanvoer installeren (NutriJet));
• installing a static mixer.
NutriJet Bypass: The EC value deviates significantly
After a successful calibration procedure of the EC measurement, the EC value differs significantly
when the water is checked further down the line or at the drippers. See NutriJet Bypass: EC control
is unstable (page 32)
NutriJet Bypass: The pressure on the pressure reducing valves in the incoming line is too
low
The first manometer on the pressure reducing valves in the incoming line indicates too low a pressure.
SolutionPossible cause
Check the external pump in the main line.The pressure in the main line is too low.
