3. Line up pin on section #1 of pneumatic block with
hole on base plate of mechanical subassembly.
4. Place a small amount of thread-locker on the
threads of the slotted-head screw used to hold
the pneumatic block and mechanical subassem-
bly together, and secure two subassemblies to
each other with the screw. Make sure screw is
as tight as possible.
5. Slide internal assembly into housing, being
careful not to crimp or pinch the current wiring,
and mate fittings in housing with ports on pneu-
matic block of internal assembly. Press down
until locked into place.
NOTE for NE-TYPE IPF’S:
Refer to Figure 8. The wiring between the
terminal block and the unit front panel, cut during
disassembly, must be rejoined using an AWG
#24-20 butt connector and heat shrink tubing
(available from Moore Industries). Use of non-
specified connectors invalidates the group N
certification.
Check to make sure that the spring is in good
condition.
14. Locate supply port air filter screen on the pneu-
matic block.
Remove filter screen with needle, and flush with
TCE. Rinse with alcohol, and set aside to dry.
Re-assembly
1. Dry all parts of both the pneumatic block and the
mechanical subassembly with the specified air or
nitrogen supply. Make sure all parts are clean
and dry.
2. Use scratch markings made earlier to make sure
that each section of pneumatic block is oriented
properly, and use small socket-head screws to
secure re-assembled block. Tighten screws to
between 35 and 45 N•m of torque (26 to 33 foot-
pounds).
