NETAFLEX™ 3G INSTALLATION MANUAL 13
ON-SITE PREPARATIONS
• The water entering the NetaFlex™ 3G should be within a pressure range of 2 to 4.5 bar
(29 PSI to 65 PSI).
NOTE
To ensure flow rate stability, the consumption of the individual irrigation shifts should be as
equal as possible. Each changeover between shifts with different consumption will result in
consumption fluctuation that will affect the EC and pH stability. The consumption of the smallest
shift should not be less than 75% of the consumption of the largest shift.
Pump house (Filter house / Fertilizer house) requirements
CAUTION
The NetaFlex™ 3G should:
• be placed in a roofed building
• not be exposed to direct sunlight
• kept at an ambient temperature between 10°C and 40°C (50°F and 104°F)
• kept at a maximum relative air humidity of 85%
• be properly ventilated
• be protected from dust
• be protected from splashes or direct spraying with water or chemicals
NOTE
In order to prevent penetration of fertilizer or acid to the soil, it is recomended that the floor of the
pump house have a slope of minimum 1% towards a gutter at its lower edge and an underground
tank at the lower end of the gutter, enabling drainage of any spill or excess.
