Storage - Flowserve D30 Installation, Operation & Maintenance Manual

2. Storage

General
The D30 positioner is a precision instrument.
Therefore it is essential that it is handled and
stored in the correct way. Always follow the
instructions in this IOM!
Note: As soon as the positioner is connected
and started, internal air venting will provide
protection against corrosion and prevent
the ingress of moisture. For this reason, the
air supply pressure should always be kept
on unless repair/maintenance work of the
positioner, actuator or valve equipment is in
progress.
Keep the cover mounted on the positioner and
replace any damaged window.
Storage indoors
Store the positioner in its original packaging.
The storage environment must be clean, dry,
and cool (15 to 26°C, 59 to 79°F).
Storage outdoors or for a longer period
If the positioner must be stored outdoors,
it is important that all the cover screws are
tightened and that all open ports/connections
are properly sealed and/or plugged.
D30 Digital Positioner
The red shipping plugs are not intended as a
permanent outdoor plug. The unit should be
packed with a desiccant (silica gel) in a plastic
bag or similar, covered with plastic, and not
exposed to sunlight, rain, or snow.
This is also applicable for long-term storage
(more than 1 month) and for long transport by
sea.
Storage in a warm place
When the positioner is stored - without air
supply pressure applied - in a warm place with
a high relative humidity and is subjected to
daily temperature variations, the air inside the
unit will expand and contract.
This means that air from outside the unit may
be drawn into the positioner. Depending on the
temperature variations, relative humidity, and
other factors, condensation and corrosion can
occur inside the unit, which in turn can give rise
to functional disorders or a failure.
