2.1.10. Setting Paddle / Basket Heights
To complete the 708-DS accessory installation, it is necessary to properly
set the Basket or Paddle shaft height – 25 ± 2mm from the bottom of the
dissolution vessel.
If basket shafts have been installed, locate the clip-on basket height
gauge. Clip the gauge onto the bottom of the basket shaft. Place the drive
unit in its operating position (fully lowered). With the shaft locking collar
loose, carefully lower the shaft until the bottom of the basket height gauge
rests against the bottom of the vessel. Ensure the shaft locking collar is
flush against the top of the spindle assembly by rotating the shaft until
resistance is met. Tighten the shaft locking collar securely with the 7/64”
T-handle allen wrench. Repeat for all active vessel positions.
Figure 2-11. Setting Paddle / Basket Heights
For units with paddle shafts installed, locate the 25-mm height spheres.
Place a sphere in each vessel. Place the drive unit in its operating
position (fully lowered). With the shaft locking collar loose, carefully lower
the shaft until the bottom of the paddle blade rests against the height
sphere. Ensure the shaft locking collar is flush against the top of the
spindle assembly by rotating the shaft until resistance is met. Tighten the
shaft locking collar securely with the 7/64” T-handle allen wrench. Repeat
for all active vessel positions.
