5 Operation
5.1 Bath
Fill each bath with the appropriate heat transfer
fluid based upon the testing temperature. Fill the
bath with the medium from the top through one of
the seven port openings using a wide neck funnel
with a 500mL griffin beaker adding about ½ L at a
time to 2" (5 cm) from the top of the bath to allow
room for fluid expansion.
NOTE: Do not attempt moving the
instrument when filled with fluid medium. Drain all
fluid before moving or relocating the instrument.
See section 7.2 of this document. Sudden starting
and stopping could result in hot bath fluid being
forcefully ejected from the bath. It could also result
in overbalancing and tipping over the instrument.
NOTE: Do not drain the bath until the fluid is at
ambient temperature.
