6.1 Vessel Placement
In order to build up adequate pressure and reduce friction, it is recommendable to place the vessel
containing fill media at the same level as pump head or preferably above the pump head level.
Placing the vessel higher than pump head level provides positive product support and may reduce
the calibration interval. It is also recommended to place the vessel as close as possible to the
pump on suction side.
