Maintenance
1.
HTHP cell assemblies should periodically be checked for:
a.
Cell Corrosion – Stress cracking or pitting
b. End Cap Compression
c. Elastomers – Check for flat spotting and melting
d.
Valve stems should be sharply pointed and not dull on outlet side.
2.
Always thoroughly clean up after each tests.
a.
Replace all elastomers if previous test was in excess of 300°F
(149°C).
b.
Clean out and blow dry if possible, the back pressure receiver.
c. Cell body must be completely cleaned with special attention to the o-
ring groove.
3. Periodically check for leaks.
a.
Cell Assembly – Immerse sealed pressurized cell assembly in a sink
filled with water – look for bubbles.
b.
Top Pressure Assembly – Immerse regulator, valves, and sealed cell
assembly in a sink full of water and look for bubbles. Hold assembly
by the gauge and do not let the gauge get wet.
c. Back Pressure Receiver – Similar to “b”. Hold assembly by the gauge
