General
The Water On Demand system enables pressure regulating of all Nipple lines
in the house from one central point and ensures a uniform pressure in all
Nipple lines. The system also enables immediate transition between different
preset pressures of all Nipple lines in the house by closing and opening of
valves at this central point (manual or solenoid* according to model).
Immediate transition between pressures enables a few pressure changes
during the day according to drinking requirements of the birds.
* Solenoid operated valves require operation by a controller or electric timer.
Pressure requirement
Inlet pressure to the Water On Demand Control Unit, minimum 2.7 bar (40 psi),
maximum 10 bar (145 psi).
Regulated outlet pressure from the Water On Demand Control Unit (to the Pressure Reducer on the Nipple Line)
maximum 2.7 bar (40 psi).
Installation
1. Wall unit (A)
• MounttheWaterOnDemandWallUnitonthewallataheightenablingconvenientoperationoftheWaterOn
Demand by the grower.
• InstalltheWaterOnDemanddownstreaminrelationtotheFilterandmedicatororanyotherdevice.
• ConnectthesolenoidvalvestotheController(onlyon
systems with a solenoid valve). The solenoid valves
are N.C (24V). This operation is to be performed
byacertiedelectrician.
2. Nipple Lines (B)
• InstallthePressureReducers
on the Nipple line head in the
same way the Plasson Line Head Regulator is installed.

Calibration
1. Calibration of the Pressure Reducers Nipple line
heads.
a. Ensure the two valves (1 and 2) are closed.
b. FilltheNipplesystemwithwaterviathe
regulator 3 (Low Pressure Range). Nipple Line
Heads(PressureReducers)shouldbeinFlush
position until all trapped air is released.
c. TurnallPressureReducersto‘Regulate’position.
d. Adjust the outlet pressure of regulator 3 to 0.5 bar
(7.0 psi). The pressure is shown on the pressure
gauge (6)
e. Verify all the adjustment knobs of the Pressure
Reducers are set to minimum pressure.
f. Drain some water through the Nipples on all lines to
ensure there is no trapped pressure in the main line
and in the Nipple lines.
g. Calibrate the pressure in the Nipple lines by turning
the adjustment knobs of the Pressure Reducers so
that the pressures in the sight tube of all Nipple
lines are equal to the Nipple line in which the
pressurewasthehighestintherstplace(verify
the adjustment knobs of this pressure reducer is set
to minimum pressure). The outlet pressure in that
specicreducershouldnotbehigherthan10cm
(4”) +/- 20%.
2. Adjusting of the outlet pressure of the regulators
3, 4 & 5 according to requirement during grow out.
a. Low Pressure Range, using the Low Pressure Range
regulator (3).
i. VerifythevalvesoftheHigh&MediumPressure
Ranges (1 and 2) are closed.
ii. Lower the Nipple lines to chick placement height.
iii. Drain some water through the Nipples on all lines to
ensure there is no trapped pressure.
iv. Adjust the outlet pressure on the regulator 3 so that
the pressure in the sight tubes (after the Pressure
Reducers) is according to the desired pressure for
chick placement [ for example - 10 cm (4”)].
b.MediumPressureRange,usingtheMediumPressure
Range regulator 5.
i. Verify the valve of the High Pressure Range (1) is
closed.
ii. VerifythevalveoftheMediumPressureRange(2)is
open.
iii.AdjusttheoutletpressureontheMediumPressure
Range regulator (5) so that the pressure in the sight
tubes (after the Pressure Reducers) is according to
the desired pressure [for example - 25 cm (10”)].
c. High Pressure Range, using the High Pressure Range
regulator (4).
i. Verify the valve of the High Pressure Range (1) is
open.
ii. Adjust the outlet pressure on the High Pressure
Range regulator (4) so that the pressure in the sight
tubes (after the Pressure Reducers) is according to
the desired pressure [for example - 50 cm (20”)].
