Description
The Select-640 Timed SSDIP is a dosing pump designed to give an initial dose of product, and then
give subsequent doses of either the same or a different dosed at timed intervals. The size of the initial
dose, the size of the timed dosages and the timed interval (in minutes) are all selected from the on-
screen controls. The components are; themain pump unit, delivery tube, and power supply (12V DC,
5A). There are no user serviceable parts inside the Select-640 SSDIP doser.
The doser will also give the initial dose on power-up.
Changing Pump Tubes
ENSURE THE POWER SUPPLY IS DISCONNECTED BEFORE CHANGING THE PUMP TUBE.
OTHERWISE ROTOR TURNING IS POSSIBLE
Removal of pump tube – Remove the black pump cover (3 screws). Unclip the pump tube at the inlet.
Lift out the pump tube whilst rotating the pump rotor by hand in a clockwise direction. When the pump
tube is clear of the rotors, completely remove the tube. Pull the old (soft) pump tube from the tube
connectors.
Push the new pump tube onto the tube connectors WITH THE TUBE RESTRAINT (ZIP TIE) ON THE
INLET SIDE. See instructions (above) to install new tube in the pump-head.
Ensure that all connectors between the pump tube and delivery tubes are securely fitted. If necessary
warm the delivery tube with warm air or water to soften it to make fitting more easy.
Pump Tube Life
The life of the pump tube will depend on many factors including the product being dosed, the back
pressures under which the pump is working, and the amount of time the pump needs to run to perform
correctly. It is suggested that, in order to maintain dosing accuracy, the pump tube is replaced on a BI-
MONTHLY BASIS or sooner if wear or disfiguration of the tube is apparent. Spare tubes are available

from your pump supplier. Note: Only tubes supplied by Dosing Solutions Ltd are recommended for use
in the Select-640 SSDIP dosing system to ensure accuracy of operation.
Safety
The Select-640 SSDIP Doser is an extremely safe unit. However, the following points should be
observed:
Normal electrical safety precautions apply. Avoid water contact with any pump parts apart from the
pump tube in normal working. Do not immerse the Select-640 SSDIP Doser.
Take precautions to ensure the Select-640 SSDIP doser can not fall into the stock solution. Consider
extra tethering if necessary. Cover stock solution at all times. If immersion does happen accidentally,
isolate the Select-640 SSDIP Doser from the electrical supply immediately.
The use of safety circuit breakers is recommended. If in doubt seek advice from a qualified electrician.
Accuracy
The Select-640 SSDIP doser is factory set to give accurate dosing. If, during normal operation, the
output needs to be increased or decreased slightly, this can be achieved via the screen command
“Adjust %”.
Electrical Supply
The Select-640 SSDIP doser uses a 12V DC power supply. This can either be supplied from a 12V
battery or via a transformer power supply from the mains electricity supply.
A 5A maximum current power supply is recommended. The Select-640 SSDIP doser normally runs
below 2A although starting currents are larger and dependant on the pumping conditions encountered.
Operation
When the electric supply is first connected, theversion of the programming will be shown.
This is the Welcome Screen
Press Adjust to start the set-up procedure.
If an Initial dose is required to be given immediately the doser is
started in operation press Yes (Set), otherwise press No.
To select the Initial Dose that will be given immediately the
doser starts operation, press adjust repeatedly until the desired
Initial Dose is shown. Then press Set.
The dosed amount is normally shown in ml. If you require a
dose amount that is not listed, please contact your Supplier.
On this screen you can select (by pressing Adjust repeatedly)
the dose (ml) that will be produced at the chosen time intervals.
With the cursor under each digit in turn, press Adjust until the
correct time is shown. Then press Set for each digit. Ensure all
leading zeros are in place. The time shown on the example
(right) is 25 minutes. 25000 would be 25,000 minutes (17.36
days).
The first timed dose will occur at the timed interval (25 mins in
this example) starting at the end on the Initial Dose.

Press Set to get to the next screen.
This screen shows that the Timed dose is 1000ml, and the Grey
pump tube should be used.
Press set.
A Tube Adjust % figure will be shown on the packet that the
pump tube was supplied in. Use the Adjust button to scroll
through (-20% to +20%) until the correct figure is shown
This feature can also be used to trim the output of the pump.
Then press set.
The Select-640 SSDIP SSDIP will display the number of timed
doses that have been produced. This figure can be reduced to
zero on this screen.
Then press Set.
If you need to fill up the delivery tube with product, press Yes,
the pump will turn continuously and show Priming… on the
screen. Press Stop when required.
As soon as the priming phase is ended, the initial dose is made
showing the screen on the right.
Once this dose is completed, the following screen is shown:
This is the normal dosing screen. The timed doseis 1000ml,
the Grey tube should be installed, a Tube adjust of +6% has
been entered, there no timed doses recorded yet, and the timer
has 25 minutes remaining until the next timed dose.
The timer will run down to 00000 at which point the next timed
dose will be given.
To make any adjustments to settings, return to theWelcome Screen and progress through the options.
To return to the Welcome Screen, press and hold Adjust from the Operational Screen.

Constant Pumping
If the priming option is selected from the menu on the control screen (see above) the pump rotor will turn
continuously regardless of the flow in the drinking line. This can be useful for filling the suction and
delivery lines prior to proportional dosing. It can also be used if a particular product needs to be dosed
quickly within a given period. The following pumping rates will be achieved when the Select-640 SSDIP
doser is set to “prime”:

It is not recommended to use the Select-640 SSDIP doser for more than 2 hours at a time in the priming
mode, as tube and motor life will be reduced.
Rotor Adjustment
The rotors in the Select-640 SSDIP pump-head are not adjustable.
Encoding
Under the rotor assembly, there is a magnet holder plate that turns with the rotor on the drive shaft.
This plate should be fitted so that the magnets are uppermost. The translucent washer should be under
the magnet holder plate.
Installation
The Select-640 SSDIP doser can be powered from a 12V DC battery or via a transformer from the
mains electricity supply. Position the dosing point so as to be convenient for a power source if power is
to be taken via a transformer from the mains. Ensure that the Select-640 SSDIP doser is properly
secured to prevent it becoming immersed in water or stock solution.
Connect the Select-640 SSDIP doser to either battery or transformer. Choose program options from
the control screen. Ensure pump tube fitted and connected to inlet and outlet delivery tubes. Place inlet
tube weight into additive liquid. Position the outlet tube to dose in the desired location.
Note: The pump will self prime. The pump can also be run dry without damaging any parts although it
is not recommended to run the pump dry for extended periods.
Power Resumption
On resuming power connection, the doser will continue at the point where electrical power was lost. The
timer will continue as from the point where power was lost.
