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.
