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.
