2.4 Diverter Valve
Adjustment
The height of the diverter valve should be adjusted to minimize
the distance above the collection tubes.
This vertical adjustment should be performed whenever different
types of racks or collection tubes are installed.
CAUTION
To prevent damage to the arm, drop former, or collection tubes,
always adjust the diverter valve to its highest position before
installing different types of racks or tubes. After installing racks
and tubes, lower the diverter valve to its operating position.
1. Ensure that the unit is in Standby. If not, touch the
Standby/On icon to place the unit in Standby.
2. Move the arm and drop former to a convenient location
over the installed collection rack.
3. While holding the diverter valve with one hand, loosen the
thumb screw(s) with the other. Do not remove the thumb-
screw(s).
4. Lower the diverter valve so that the drop former is close to
the top of the collection tubes (Figure 2-14). Generally, a
1
/
2
-inch or 1 cm space between the drop former and the top
of the tubes will sufficiently allow unobstructed movement
of the arm.
5. Tighten the thumbscrew(s) to secure the diverter valve
position.
6. Move the diverter valve over the tubes in each corner of the
rack to ensure there is clearance.
7. Turn on the fraction collector by touching the touch screen
display. The arm will return to the home position. The drop
former should clear the top of the tubes.
