3 Unpacking and Storage
3.1 Unpacking
1. While unpacking the Logix 3400IQ positioner, check the packing list against the materials
received. Lists describing the system and accessories are included in each shipping
container.
2. When lifting the system from the shipping container, position lifting straps to avoid damage to
mounted accessories. Systems with valves up to six inches may be lifted by actuator lifting ring.
On larger systems, lift unit using lifting straps or hooks through the yoke legs and outer end of
body.
c WARNING: When lifting a valve/actuator assembly with lifting straps, be aware the
center of gravity may be above the lifting point. Therefore, support must be given to
prevent the valve/actuator from rotating. Failure to do so can cause serious injury to
personnel or damage to nearby equipment.
3. In the event of shipping damage, contact the shipper immediately.
4. Should any problems arise, contact a Flowserve Flow Control representative.
3.2 Storage
Control valve packages (a control valve and its instrumentation) can be safely stored in 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.
Long Term Storage of Logix 3000 series Positioners in Humid Locations
The Logix 3000 series positioners are designed to operate in humid environments when connected
to a proper instrument air supply. There are some occasions when valves and positioners are stored
at job sites or installed and commissioned and then left without instrument air for months. To make
startup easier for units that are left without instrument air and insure that the positioners will be
ready to operate, it is recommended that the vent assembly of the positioner be sealed preferably
with a desiccant pouch sealed with the vent assembly.
