NOTE: All assemblies are tested at the fac-
tory for proper operation and leakage. If the
valve does not pass the field test, it is most
likely due to a fouled check valve. This is not
covered by the factory warranty. The valve
cover(s) must be removed and the check
seats inspected and cleaned. Any damage
or improper operation caused by pipeline
debris or improper installation/start-up is not
included in the factory warranty. In case of
a possible warranty claim, contact your local
supplier or FEBCO Representative. DO NOT
REMOVE THE VALVE ASSEMBLY FROM THE
PIPELINE.
