7. water bellows at 100 and adjust the chemistry bellows output to 400 mls minute It is recommended to operate the bellows as close to 100 as possible while still keeping the desired ratio If the ratio is less than 4 1 2 1 decrease the water bellows If the ratio is greater than 4 1 2 1 decrease the chemistry bellows 9 11 The third bellows on the fixer pump is a 1 2 bellows used for adding hardener This bellows has a maximum rate of flow of 45 mls minute Consult your chemistry manufacturer for the appropriate amount of hardener to be added to the fixer One fluid ounce equals 29 57 mls Drain the water from the pump concentrate inlet tube before inserting it into the concentrate tank Also drain the hardener line before using it Reattach the pump outlets to the fittings to the original locations NOTE For best performance of the metering pump operate the bellows between 50 to 100 CONTROLS General Comments Electronic Controls The RAM C is controlled by a state of the art microprocessor based Programmable Logic Controller PLC This PLC is versatile and able to be updated easily by just changing the software program The PLC uses the input from the float switches and the manual switches then provides control for all the pumps and the low level alarm The PLC keeps the tanks full by monitoring the high level switches and makes sure the tanks don t run dry by monitoring the low level switches and sounding the
