Pump Tube Colour

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.
