Abstract:
A method of controlling delivery of water and a plurality of chemical products to washers comprising the steps of:a) coupling a water supply from a reservoir to an input end of a distribution means;b) coupling a plurality of chemical product containers to said distribution means through corresponding distribution pumps;c) operating said distribution pumps to distribute specified chemical products from said containers into said distribution means;d) coupling transfer pumping means to said distribution means;e) operating said transfer pumping means to pump water from said reservoir into said distribution means wherein water is mixed with said chemical products and wherein each such chemical product is diluted;f) selecting a specified machine washer and connecting an input line for said specified washer to an output end for said transfer pumping means;g) operating said transfer pumping means to transfer fluids from said distribution means to said specified washer;h) connecting a controller means to said output end for said transfer pumping means for controlling delivery of water and chemical products to said specified washer by providing a fluid pressure sensor at the output end of said transfer pumping means for monitoring and detecting a high or low pressure in said input line for said specified washer; andi) transmitting an interrupt signal to said controller means whenever a corresponding chemical product or water is needed for said specified washer.
