EEE - Model FF 600 - First Flush System - Specifications

All wash-points must be taken from a supply that passes through the Control Panel. When a washdown activity is detected by the system all run-off is diverted to a Holding Tank or similar for treatment or proper disposal. At the commencement of rain the system will be controlled by the PLC to deliver a predetermined volume (i.e. number of chamber drops) that is equivalent to a “First Flush” of the site. The Fox PLC has features that are unique and include the following:- FIRST FLUSH VOLUME CONTROL... this function allows the first flush volume to be changed on site if more or less run-off needs to be collected; WASHDOWN SENSING... This function ensures that a First Flush activity only commences after a washdown operation has occurred; DELAY DROP FUNCTION... this function allows for the residue from a washdown activity to drain to the equipment and diverts it for treatment; HOUSE CLEANING ALARM... This feature will activate if the diversion valve fails to close. Usually failure to close indicates that the system is in need of a ‘housekeeping’ activity.
