4 STORAGE AND UNPACKING
4.1 Storage
FLOWSERVE Control valve packages (a control valve and its instru-
mentation) are typically well protected from corrosion. Nevertheless
FLOWSERVE products must be stored in a clean, dry environment such
as an enclosed building that affords environmental protection. Heating
is not required. Control valve packages must be stored on suitable
skids, not directly on the floor. The storage location must also be free
from flooding, dust, dirt, etc. Plastic caps are fitted to protect the flange
faces and positioner ports to prevent the ingress of foreign materials.
These caps should not be removed until the valve or positioner is
actually mounted into the system.
If FLOWSERVE products (especially sealing materials) have been in
storage for longer periods check these for corrosion or deterioration
before using these products. Fire protection for FLOWSERVE products
must be provided by the end user.
4.2 Unpacking
While unpacking the valve and/or Logix 500MD+ positioner, check the
packing list against the materials received. Lists describing the system
and accessories are included in each shipping container.
In the event of shipping damage, contact the shipper immediately.
Should any problems arise, contact a Flowserve Flow Control Division
representative.
4.3 Pre-installation Inspection
When installing a positioner, verify the shaft has not been damaged
and that the plugs and cover are in place. The plugs keep debris and
moisture from damaging the internal components of the positioner. If
the positioner has been contaminated, clean the positioner components
gently with a soft damp cloth. Some components may be removed
for better access. See section 13 MAINTENANCE AND REPAIR. Check
connectors to ensure that no debris is present. Port screens can be
removed with a flat screwdriver for access to internal passages.
