Servicing
The regulator was checked by SAMSON
before it left the factory.
− Certain test results certified by SAMSON
lose their validity when the regulator is
opened. Such testing includes seat leakage
and leak tests.
− The product warranty becomes void if
service or repair work not described in
these instructions is performed without
prior agreement by SAMSON's After-sales
Service.
− Only use original spare parts by
SAMSON, which comply with the original
specifications.
SAMSON's After-sales Service can support
you in drawing up an inspection and test
plan for your plant.
