Re-Assembly Procedures
Unless noted, the ASU's re-assembly is simply the reverse sequence of the disassembly procedures.
However, the following "cautions" should be followed (whenever they apply) for proper re-assem-
bly:
CAUTION: In general, all O-RINGS AND SEALS must be replaced whenever
hot-melt equipment is re-assembled. All new o-rings must be lubricated with
o-ring lube (PN N07588).
CAUTION: TAPERED PIPE THREADS are found on air line fittings used with the
pump air supply and on the outlet filter manifold. Apply thread sealant (PN
N02892) whenever tapered pipe threaded parts are re-assembled.
CAUTION: SOME FITTINGS used for adhesive on the ASU have straight threads
and o-ring seals. Use of thread sealant is not necessary with these parts, but the
o-ring seals should be clean and lubricated. Tighten straight-threaded parts and
fittings until their shoulders are firmly seated. Excessive torque may damage
straight-threaded parts and the use of power wrenches is not recommended.
CAUTION: HOT-MELT RESIDUE must be cleaned from parts before they are
re-assembled, particularly from threaded parts. As a precaution against adhesive
residue preventing proper re-assembly, threaded parts must be re-tightened at
operating temperature.
