Attaching other kinds of manifolds

• The flanges contain a 1" female thread to enable connection of other

kinds of manifolds. Attach the manifolds here using a proper pipe thread

sealant

• If the manifolds should be offset, use a spacer or a longer insert.

• We recommend to use a union connection between the manifolds and

the base module. This facilitates disassembly in case of repairs.

Changing the number of loops

of the segmented plastic manifold

• Make sure to adjust the number of loops before installing the module in

a manifold cabinet, since it may be impossible to remove the threaded

rods with the unit mounted in a cabinet.

Reduce number of loops, disassembly

• Remove both nuts at the end plate

• Remove end plate and unneeded manifold segments

• Cut the threaded rods to proper length [55 mm for every segment

removed]. Caution: take care not to damage the thread or the seal

surface of the last segment.

• If the threaded rods cannot be cut in place, remove them and shorten

them elsewhere. Caution: take care not to damage threads.

Increase number of loops, disassembly

• Remove both nuts at the end plate

• Remove the end plate

• Remove both threaded rods

• Install new threaded rods with the appropriate length [additional 55 mm

for every segment]. Caution: take care not to damage the thread.

• Install additional segments

Reassembly of manifold

• Caution: if manifolds have been in operation, it is necessary to clean

carefully the seal rings and the seal surfaces of each segment as well

as the end plates.

• Reinstall the end plates and tighten the nuts equally.
