Operating Warnings S3 Pump Controller
Overview
S3
Thank you for buying an S3 Static RO Controller. This is an advanced pump controller
solution for your system and should give you complete control over water production.
Follow this manual carefully. It explains in detail how to connect and operate the pump
controller. Most connections are shown on the system diagram, however further details
are provided throughout the rest of the manual. Complete ALL wiring connections
BEFORE connecting the unit to the mains supply. Ensure the controller, sensors and
cables are firmly fixed in place before using your controller.
The S3 controls the filling side of your water tank (inlet and pure water production). The
controller has a number of other advanced features to increase ease of use and report
on the operational status of the system.
Filling
The controller opens the solenoid valve to fill the water tank until the high level float
switch activates. This is a one time operation and will stop once the tank is full. The
controller will automatically flush your RO membrane on a regular basis to keep it at
optimum performance and to increase its service life.
The controller can be configured to stop filling if the TDS is too high. This can be set to
either after the RO membrane (due to an RO failure) or after the DI vessel (if resin is
spent). It will also shutdown the fill if mains water pressure is too low.
The controller has a flowmeter to measure the amount of water used, this can also
indicate the filter life.
The controller also incorporates a pressure sensor which allows the controller to report
on the state of the carbon and sediment filters. The addition of a pressure sensor also
allows the controller to shut down the pump in the event of mains water failure.
Fitting
The S3 is supplied already wired. There is no need to disconnect any wires. Follow these
instructions carefully and refer to the system diagram.
IT IS RECOMMENDED THAT THE S3 IS FITTED AGAINST A WALL OR SIMILAR VERTICAL
SURFACE.
1. Ensure the S3 is NOT PLUGGED INTO THE MAINS SUPLLY.
2. Remove the top cover by loosening the four corner screws. Remove top cover by
folding to the right.
3. Screw unit to the wall or vertical surface through the four ready drilled holes in the
back box corners.
5. Carefully replace the top cover and tighten the four corner screw.

Set up the system carefully. Follow these instructions very closely, paying close
attention to all warnings and diagrams.
The S3 is fused at 5A. Always fit the correct 5A quick blow mains fuse. The S3 can
control pumps up to 1000VA (1000W). DO NOT USE THE S3 WITH PUMPS GREATER
THAN 1000VA.
The S3 and pump mains socket are supplied in a waterproof enclosure. The mains
plug is NOT WATERPROOF. Do not plug the mains plug into a socket that could
become wet during operation, failure to do so will result in damage to the unit.
Ensure the 230Vac pump mains socket enclosure is closed tightly before turning the
controller on. This will prevent the connection getting splashed or wet during use,
failure to do so will result in damage to the unit.
Filling & Fitting
THE UNIT MUST BE INSTALLED BY A COMPETENT ELECTRICIAN OR ELECTRICAL
ENGINEER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD INVALIDATE
THE CONTROLLER WARRANTY.
ALWAYS DISCONNECT THE MAINS SUPPLY BEFORE OPENING UNIT.
ALWAYS DISCONNECT THE MAINS SUPPLY BEFORE CONNECTED THE PUMP.

System System
Filling
Connect the pump controller following this diagram. Use only wire from the middle
gland. NOTE: only fit the fuse once all connections are made.
To start filling the tank simply press the ‘F’ (Fill) button briefly. This will activate the RO
inlet solenoid valve, allowing water to fill the tank, until the float switch detects that the
tank is full.
When fill is started the system will open the
Autoflush valve for 5 mins (in every hour) to
clean RO.
The Autoflush valve will then close when
flushing has finished and controller will
continue to fill via the RO inlet valve.
After flushing the booster pump will turn
on if ‘boost on flush’ is ‘off’.
System
Full
When the tank water level rises sufficiently
to activate the level switch, filling is stopped.
All valves are closed.
To manually stop the tank filling, (if ‘On
Demand’ is ‘Off’) press the ‘F’ (Fill) button
again breifly. The display will remove the
‘Fill’ message.
NOTE 1: The solenoid valve will be turned off if the unit detects a loss of mains
water pressure (below 10 PSI).

TDS Wiring S3
For the TDS probes in John Guest 1/2” equal tee pieces (not supplied) as shown on
the diagram.
We recommend RO TDS probe to be fitted after the RO (reverse osmosis) filter. You can
then check the RO is working correctly. If you see these values rising over time it could
indicate a problem with the RO.
We recommend DI TDS probe be fitted after the DI (de-ionising) vessels. You can then
check DI vessels are working (and that the resin is not depleted).
For good cleaning a TDS value below 5ppm after the DI is recommended.
The TDS function provides an indication of the water purity. The TDS values displayed
are in ppm (parts per million). The TDS meter has a max reading of 50ppm.
To monitor the current TDS reading press enter repeatedly until it displays the TDS screen.

Take care when handling TDS probes. Do not damage gold plated contacts
as this will affect TDS accuracy.
Ensure gold plated contacts are clean before use. Clean with ISOPROPANOL
alcohol (IPA) and a soft cloth.
Dirty contacts will affect TDS accuracy, clean with IPA if readings appear to
deviate over time.
