Operating pressure: 200 psi inlet pressure suggested for best operation. We have provided basic calculations online . (average pressure loss through the eductor 30-40%) 2. Bypass Switch arrow pointing toward the FOAM to educt foam concentrate. To flush the system or break the venturi turn the bypass to the WATER position. (Note: the bypass only moves about 3/4”) 3. Hose length after the eductor: 1” hose: no more than 200’ past the eductor (30GPM eductor only) 1-1/2” hose: no more than 150’ past the eductor (See example online) 1-3/4” hose: no more than 200’ past the eductor 4. Nozzle must flow at least the rated flow of the eductor. If the nozzle flows less than the eductor rating, venutri will not be achieved and no foam will be created. If you are using a selectable nozzle, move the flow to the next higher setting if no foam is generated. 5. Dial percentage that is desired should be pointing at the indicator arrow or at the pickup tube coupling depending on the age of the eductor. Water Bypass Operation: Arrow pointing to FOAM, the water is forced through the center creating the venturi and makes foam. Arrow pointing to WATER, the water is allowed through the bypass holes breaking the venturi and stopping foam for flush or a higher desired flow. 888-663-4966
