n Distance between equipment and product storage housing as less as possible
(length of the suction hose max. 3 m!)
For a better venting, the suction line should
always be designed upward in the direction of lifting vessel.
n If the metering point lies below the lifting vessel, a pressure control valve or metering
valve with corresponding opening pressure must be used, in order to avoid thedraining
of lifting vessel through the pump(s).
n In order that while dealing with the Click & Plug connection coupling or through
suspended
suction hoses, there are no high loads on the
Connexx System and the
coupling connection on the containers, it is recommended to mount a pull relief for the
suction hose.
n The installation site should be selected in such a way that the exhaust air line from the
injector can be run into a safe area. Very long suction lines can reduce the
suction power of the injector and necessitate an increase in the nominal diameter
