December 20, 2019
Pick one of the three examples that most closely matches your situation and adjust
the flow, tank size and desired final dosage level to your installation requirements.

1.0 Quick Start Guide
1.1 Example 1: Tank Recirculate Mode; 8 cubic meter tank, watermaker
with 625 liters per hour, and 40 PPB Silver
The watermaker run signal should be connected to the In 3 terminals, power
to the input power terminals and the Ag-S connected to the water system
according to the drawing: Tank recirculate mode example 1.
Set Water Tank Capacity – Enter the max. capacity of your fresh water tank
1. Select Setup from the main menu and press Enter
2. Select Tank/Dir and press Enter
3. Select Tank recirculate and press Enter
4. Select Set and then Select the units of measure, Cubic meters and
press Enter.
5. Use the up and down arrows to set the value to 8.0 and press Enter
6. Press the left arrow 3 times to get back to the Setup menu.
Configure Input
7. Select Inputs and press Enter
8. Select In 3 and press Enter
9. Select Fixed flow to tank and press Enter
10. On the first entry for this input selection, skip to the next step. If making
a change to this selection then Select Set
11. Select the units of l/hr and press Enter; and then the arrows to set the
value to 625 and press Enter
12. Select Input polarity;Closed=On is normal and then press enter
13. Press the left arrow once to get back to the Setup menu.
Set Ag Concentration
14. Select Ag PPB and press Enter; Use the arrows to set the value to 40
and press Enter.
Adjust Flow through Chamber
15. To set the flow rate through the chamber use the Flush menu also
under Setup to turn the solenoid valve V01 on and off. Turn the flow
on by pressing Enter and adjust the flow regulator to the chamber to
3l/min. Confirm that the –Flow on the display turns to ▓Flow when flow
is on and back when off. See Section 11 of the manual to adjust the
flow switch.
When the watermaker is running the Ag-S will count up the amount of water that has
been produced. Once enough water has been produced to allow the unit to operate
for 2 minutes the Ag-S will start to generate silver ions and continue to run until the
desired PPB is reached.

1.2 Example 2: Tank Recirculate Mode; 20 cubic meter tank, watermaker
with flow meter (10 l/pulse) on output, bunker line going through the
same flow meter, and 50 PPB Silver.
The flow meter pulse output line should be connected to the In 1 terminals,
power to the input power terminals and the Ag-S connected to the water
system according to the drawing: Tank recirculate mode with Flow Meter;
Example 2. The flow meter is on a combined line for the output of the
watermaker and the bunker line.
Set Water Tank Capacity – Enter the max. capacity of your fresh water tank
1. Select Setup from the main menu and press Enter
2. Select Tank/Dir and press Enter
3. Select Tank recirculate and press Enter
4. Select Set and then Select the units of measure, Cubic meters and
press Enter.
5. Use the up and down arrows to set the value to 15.0 and press Enter
(15 is the highest possible value)
6. Press the left arrow 3 times to get back to the Setup menu.
Configure Input
7. Select Inputs and press Enter
8. Select In 1 and press Enter
9. Select Flowmeter pulses and press Enter
10. On the first entry for this input selection, skip to the next step. If making
a change to this selection then Select Set
11. Select the units of l/pulse and press Enter and then the arrows to set
the value to 10 and press Enter
12. Select Input polarity;Closed=On is normal and then press enter
13. Press the left arrow once to get back to the Setup menu.
Set Ag Concentration
14. Select Ag PPB and press Enter; Use the arrows to set the value to 50
and press Enter.
Adjust Flow through Chamber
15. To set the flow rate through the chamber use the Flush menu also
under Setup to turn the solenoid valve V01 on and off. Turn the flow
on by pressing Enter and adjust the flow regulator to the chamber to
3l/min. Confirm that the –Flow on the display turns to ▓Flow when flow
is on and back when off. See Section 11 of the manual to adjust the
flow switch.
When water is going through the flowmeter the Ag-S will count the pulses, which
represent the amount of water that has been produced or bunkered. Once enough
water has flowed to allow the unit to operate for 2 minutes, the Ag-S will start to
generate silver ions and continue to run until the desired PPB is reached.

Tank recirculate mode with Flow Meter; Example 2

1.3 Example 3: Direct flow mode; flow from watermaker is a fixed 75 liters
per minute and the desired silver level is 45 PPB.
The Direct Flow signal should be connected to the In 1 terminals, power to
the input power terminals and the Ag-S connected to the water system
according to the drawing: Direct flow mode; Example 3.
Select Direct Flow Mode
1. Select Setup from the main menu and press Enter
2. Select Tank/Dir and press Enter
3. Select Direct flow and press Enter; then Confirm by pressing Enter
4. Press the left arrow twice to get back to the Setup menu.
Configure Input
5. Select Inputs and press Enter
6. Select In 1 and press Enter
7. Select Direct flow and press Enter
8. Select the units of l/min and press Enter and then the arrows to set the
value to 75 and press Enter
9. Select Input polarity;Closed=On is normal and then press enter
10. Press the left arrow once to get back to the Setup menu.
Set Ag Concentration
11. Select Ag PPB and press Enter; Use the arrows to set the value to 45
and press Enter.
Adjust Flow through Chamber
12. Under the Setup menu go to the Flush menu. This will allow you to
see the status of the flow switch. The On/Off feature that opens and
closed the flow valve relay is not used in the Direct Flow mode.
13. Adjust the Flow Regulator/Indicator to the chamber so that it is fully
open
14. With water flowing through the system, adjust the Throttle Valve so that
just over 3 liters per minute is flowing through the chamber
15. Adjust the Flow Regulator/Indicator to reduce the flow to the chamber
to 3 liters per minute
16. Confirm that the –Flow on the display turns to ▓Flow when flow is on
and back when off. See Section 11 of the manual to adjust the flow
switch.
