In preparation for the plate removal and installation process, the operator must evaluate the
meter system to determine the amount of time between the Top (14) fluid evacuation and the
plate change to the full replacement of the Clamping Bar (12 or 12HP), the Sealing Bar (9 or
9HP), and the Sealing Bar Gasket (9A, 9A-HP or 9CF) back on the Top (14).
If the operator determines that the time between the Top (14) fluid evacuation and plate change
to the full replacement of the Clamping Bar (12 or 12HP), the Sealing Bar (9 or 9HP), and the
Sealing Bar Gasket (9A, 9A-HP or 9CF) back on the Top (14) is less than 15 minutes, then the
operator may use the “QUICK CHANGE” procedure.
If the operator determines that the time between the Top (14) fluid evacuation and the plate
change to the full replacement of the Clamping Bar (12 or 12HP), the Sealing Bar (9 or 9HP), and
the Sealing Bar Gasket (9A, 9A-HP or 9CF) back on the Top (14) is greater than 15 minutes, then
the operator must use the “EXTENDED TIME” procedure.
If, for any reason, the operator cannot determine the total time between the Top (14) fluid
evacuation and the plate change to the full replacement of the Clamping Bar (12 or 12HP), the
Sealing Bar (9 or 9HP), and the Sealing Bar Gasket (9A, 9A-HP or 9CF) back on the Top (14), then
the operator must use the “EXTENDED TIME” procedure.
Prior to performing any maintenance or Orifice Plate (13) installation and removal operations on
the Senior, personnel must visually confirm the presence of the Indicator Plate (5A) on the Slide
Valve Shaft (5) and the Indicator Pointer (5B) on the Body (4). Both the Indicator Plate and the
Indicator Pointer must be installed to operate this equipment safely.
