After successful testing of the pressure, release the pressure,
before the store is connected to the heating system.
Procedure for leaking end seal behind pressure profile
If a passage at the end seal is leaking despite re-tightened
barrel nut, proceed as follows:
1. Empty modules
2. Remove the nut of the loading and unloading pipes on
the affected side and remove the pressure profile.
3. Pull out loading and unloading tubes with end seal so
far that the affected seal is free.
4. Check for cause of leakage.
Procedure for leaking connection between internal modules
Leaking module connections are found during pressure test,
as described below:
1. Empty modules
2. Remove the nuts of the loading and unloading pipes.
3. If enough space, it is sufficient to dismantle only one
pressure profile. The loading and unloading pipes are
pulled out to this side. Otherwise, remove the pressure
profile on both sides.
4. Pull out loading and unloading tubes with end seal so
far that the affected seal is free.
5. Remove the connecting rod, loosen and remove centre-
ing bolts on affected modules.
6. Slide modules apart where leaking.
Check for cause of leakage
1. Leakage between store plate and gasket?
Does the seal fit properly in the sheet metal?
Is the gasket sleeve damaged?
2. Leakage between the gasket and stainless steel sleeve?
Is the stainless steel sleeve damaged?
Is the gasket sleeve damaged?
3. End seal: leaks at O-ring seal?
Is the O-ring sealing surface of the stainless steel end
sleeve damaged?
Is the O ring damaged?
4. If necessary consultation with technical support and, if
necessary, order a replacement seal.
5. Fix cause of the leakage.
6. Slide the modules together.
7. Replace connecting rod and loading and unloading
loading pipes.
8. Insert the end seal and bolts, tighten nuts.
9. Pressure test and fill in accordance with procedure
above.
CAUTION:
If a gasket is removed and replaced, ensure that it
is reseated correctly.
Clean the sealing surfaces on the container and remove
any traces of rust. Apply a thin layer of lubricating grease
When the store is full to the top remove the last of the air
through the air vent.
The manual air vent on the end module opens by pulling on
the hose.
It closes by pressing on the vent.
With a test
pressure of 3.9 bar
(based on the require-
ments of the European pressure equipment directive, 1.3
times nominal pressure) perform the pressure test.
Use a class 1 pressure gauge.
CONTROL
The following points must be documented:
Passages on end seals dry (check slot in 2" washer),
otherwise
depressurise store
and tighten barrel
nuts of loading and unloading loading pipes in
small
increments: not only the affected gland, but
also the others
, so that the entire pressure profile
gets more pressed against the container.
Re-tighten
alternately on either side in doing so
.
Floor between storage modules dry
Vent plugs dry.
