4. Installation and Operation
Before installation, it is essential to verify that the capsule assembly type selected is suitable for
the product to be filtered and to follow the appropriate instructions listed below and the
diagrams in:
Appendix A: Chassis User Instructions — Pilot Scale on page 8
Appendix B: Chassis User Instructions — Process Scale 5 and 10 High on page 10
Appendix C: Chassis User Instructions — Series Filtration on page 12.
4.1 Installation
The Stax capsule system must only be used in conjunction with the appropriate supporting
chassis. Ensure that the required manifolds and capsules are installed in the correct
orientation for flow and that the inlet and outlet ports are adequately supported.
The distribution manifolds have the flow direction indicated on the pipes.

1. Ensure that the support chassis is located in a stable and level position. The process
scale chassis must be bolted securely to the floor or when fitted with wheels these must
be fully locked.
2. The Stax capsule assemblies must be stacked in a vertical orientation. Assembly of the Stax
capsule system begins with the correct placement of a distribution manifold on to the base
of the chassis. Capsules are then stacked on top in the correct orientation, ensuring that
the sealing gasket is correctly positioned flat between each item within each capsule and
distribution manifold retaining lugs, and then topped with the appropriate manifold.
For systems requiring flow in and out via the bottom distribution manifold, a vent
manifold must be fitted to the top of the stack. For bottom in and top out flow,
the stack must be topped with a distribution manifold. Refer to the Applications Note
for recommendations on when to use the alternative flow modes. Fluid flow must be
in the direction indicated on the distribution manifold and must be maintained within
the specifications.
3. The Stax capsule assembly may also be operated in series filtration mode in the same
process scale chassis with two sets of capsules containing different filter sheet grades.
Refer to Appendix C: Chassis User Instructions — Series Filtration on page 12 for correct
assembly. Both capsule sets should be completed with a vent manifold.
In series mode, the 10-high chassis is limited to 9 large capsules and in the 5-high
chassis to 4 large capsules.
