molbloc INSTALLATION
!
Loosen the interconnecting nipple clamp (3) so that the nipple can move freely in its rubber grommet.
Move the nipple away from the molbloc cradles to allow maximum room for molbloc insertion.
#
#
#
#
Place the molbloc in the molstic molbloc cradles (be sure flow orientation is correct). Check that no debris
is under molbloc.

Connect and tighten the upstream (valve side) molbloc VCR connection using a soft O-ring and following
the procedure provided in Document 560009 (Recommendations for molbloc Installation) supplied with the
molbloc.

To remove a molbloc from the molstic, reverse the procedure. Break the downstream molbloc VCR
connector and pull the interconnecting nipple away from the bloc. Break the upstream molbloc
VCR connector. Remove the molbloc.
DUT PLATFORM INSTALLATION AND OPERATION
!
Insert socket cap screws (1) through two parallel mounting holes in the molstic
base corresponding to the desired DUT platform position.

Rotate thumbwheels (2) to position the DUT platform at the desired height so that the DUT fitting aligns
with the molstic downstream fitting.
MAINTENANCE AND RECOMMENDATIONS
)
Filter:
The molstic filter is a sealed 2 micron pleated mesh filter (NUPRO SS-4FW-VCR-2). It can be
cleaned by backflushing. To backflush, it must be removed from the molstic. When removing, cleaning
and installing the filter, the metallic VCR gaskets (NUPRO SS-4-VCR-2-GR) must be replaced and all
manufacturers’ recommendations followed.

Handling:
molstic should not be picked up or carried by its components. Always handle the molstic by
its base.
