used to set the initial height. Once the unit's height is calibrated the Quick
Change Height Adjustment Knob (Paddles or Baskets) procedure should be
followed to switch between paddles and baskets.
Initial Height Setting for Paddles and Baskets:
1. Press brake release button and raise drive unit.
2. Turn height adjustment knob (see Figure 2-9) to either horizontal position.
3. Loosen shaft locking collars so they slide freely on shafts. Use 7/64” Allen
(hex) wrench.
4. Raise shafts slightly by pulling up on protective covers (gray handles).
5. IMPORTANT: Install paddle blades on all shafts, even if baskets will be used
for testing. Paddle blades must be used to set shaft collars!
6. Lower drive unit slowly to lowest position so drive plate extension rests on
height adjustment knob.
7. While applying slight downward pressure on drive unit, let go of brake
release button to lock drive unit in place. Make sure drive plate extension
touches height adjustment knob.
8. Lower shaft gently until paddle blades touch the bottom of each vessel.
9. Lock each shaft collar using 7/64” Allen wrench.
10. Raise the drive unit approximately six inches.
11. Turn the height adjustment knob to “PADDLES” position as seen from the
front of the unit (see Figure 2-9).
12. Lower drive unit gently until it comes to rest on height adjustment knob and
release brake button.
13. Check paddle or basket height using Distek HeightChek or other means.
Verify and record distance from bottom of each paddle or basket to bottom
of vessel. (Do not change the position of the shaft collars.)
14. To switch to baskets, raise the drive unit and install baskets on the shafts.
15. Turn the knob to "BASKETS" position (see Figure 2-9).
16. Lower drive unit gently until it comes to rest on height knob and release
brake button.
17. Check paddle or basket height using Distek HeightChek or other means.
Verify and record distance from bottom of each paddle or basket to bottom
of vessel.
If shafts do not slide up smoothly, a very thin film of
lubricant may be applied to shaft, only to area just
below spindle. Wipe off any excess grease. Move shaft
up and down gently to distribute lubricant. If
necessary, Distek recommends Dow Corning High
Vacuum Grease. Do not use a lubricant which may
affect your test results.
