Fiberglass reinforced plastic (FRP) Pressure vessels are extremely rugged and durable. They
are designed for safe, long-term service when they are handled and installed properly. However,
damage to the vessel shell or related components from improper handling or installation could
result in malfunction or explosive head failure while in service. Therefore exercise the following
precautions whenever handling vessel.
1. Never lift or move a vessel by placing anything inside it. The vessel is durable and ideally
suited to its purpose, but careless handling can permanently damage it.
2. Be careful not to scratch the inside wall of the shell, especially in the sealing area inboard of
locking segment groove near the end.
3. Do not drop vessel or allow it to hit hard on the ground or against other objects.
4. Do not apply undue stress to shell.
5. Before using a forklift to handle the vessel, pad the forks to lessen the chance of damaging
the shell. Severe scratches or gouging of the vessel can result in failure of the vessel wall.
6. Do not allow undue stress to act on the Feed/Concentrate port, which might cause impact
damage to the port area, leading to leakage. Do not use the Feed/Concentrate port or the
permeate port as a tool to lift the pressure vessel or as a support to manifolds. Manifolds
should be self-supporting.
NOTE ON IMPACT DAMAGE
Exterior vessel damage can lead to early vessel failure. Damage received in shipment should be
reported to the shipping company immediately upon receipt minor damage such as scratches
that go no deeper than the paint may be acceptable. Call the Pentair customer service
department for advice if in doubt.
STORAGE
Pentair recommends storing the vessel in the received packing or in a secure place. Vessel
should not be stored in such a manner that they will roll over and get damaged.
If ambient or storage temperature drops below or increase above the operating temperature than
do not use such vessel under same condition wait to normalize the temperature within the
operating range.
