This section is intended only to provide guidelines for dealing with problems that might arise
while working with CodeLine Series pressure vessels.
These guidelines are not in any way a replacement for the good industrial practice required to
ensure safe operation. We recommend that only a qualified engineer, experienced in servicing
high pressure hydraulic systems, carry out the following tasks.
Preliminary Inspection
Inspect the vessel at each end for corrosion,
which may interfere with head assembly
removal. If corrosion is evident, proceed as
follows:
1. Loosen any deposits with a small
wire brush and/or a medium grade
piece of ScotchBrite
Loosening Deposits
WARNING
Do not use a wire brush on components made
from Engineering Thermoplastic.
2. Flush away loosened deposits with clean
water.
3. Proceed with instructions given in
"Opening the Vessel" section.
Difficulty in Opening Vessel
NOTE
Recommendations listed here are intended
only as a guide. If the head assembly is still
difficult to remove after all
recommendations have been followed, call
Pentair for technical assistance.
TROUBLE SHOOTING
TM
.
Head Retaining Ring
1. Will not release from the Retaining Ring
Groove.
A. Apply penetrating fluid (such as WD-40 or
LPS-1) to interfacing areas of retaining
ring.
B. With a screwdriver handle or similar tool,
tap the retaining ring to release the
bond.
C. Again, attempt to remove the retaining
ring.
Applying penetrating fluid
CAUTION
When applying penetrating fluid, be careful
to avoid element contamination.
