Claim:
1. A method of assembling a device for filtration with a set of least one filter cassette comprising: providing a manifold providing fluid connection and mechanical connection comprising at least one flow inlet for a fluid to treat, at least one flow outlet for a treated fluid and a network for conveying said fluid to treat and said treated fluid, said manifold having a bearing surface for a said filter cassette, through which bearing surface emerge cassette feed ports and cassette return ports communicating with said network for conveying, which cassette feed ports and cassette return ports are configured to communicate with conduits formed in a said filter cassette bearing against said bearing surface; providing a clamping plate; and providing at least one rod which extends between said manifold and said clamping plate; providing at least one actuator, which is provided with a body and a member moveable relative to said body, which moveable member has an extended position and a retracted position in which said moveable member has been moved through a predetermined travel relative to its extended position, by virtue of which the clamping plate has a starting position in which said plate is away from said set of at least one filter cassette and a clamped position in which said plate is approached and compresses said set of at least one filter cassette against said manifold; wherein said body is carried by said manifold and said moveable member carries said rod; actuating said actuator to drive said clamping plate via said at least one rod to its clamped position in which said moveable member is in an intermediate retracted position in which said moveable member has moved through a shorter travel than said predetermined travel relative to its extended position; and providing a sleeve fixed to said manifold on which said actuator is movably mounted.
