7.5 Installing the Kit for Low Flow Rates
Description
Kit for low flow rates, including:
1.0 mm ID diverter valve with 0.4 mm ID PEEK drop former
The kit for low flow rates includes a tool for installation and a piece of 0.3 mm ID PTFE
tubing. Before you start, make sure that you have all parts of the kit at hand.
1. Shut down and unplug the fraction collector. Set the pump flow to 0.
2. Dismount the current diverter valve from the assembly (→ page 67).
3. Connect the diverter valve cable to the auxiliary I/O connection on the AFC-3000 rear
panel (→ Fig. 2, page 18). Tighten the knurled nut finger-tight.
4. Remove the two valve screws that are attached to the new diverter valve.
5. Remove the drop former and drop former screw from their packaging and insert the
drop former into the screw (→ Fig. 27). Then place the screw in the diverter valve
(bottom side). Use the screwdriver tool shipped with the kit to carefully tighten the
screw. You may have to retighten the screw if you observe leakage during operation.
6. Mount the diverter valve to the diverter valve assembly by using the hexagon wrench
shipped with the kit (→ Fig. 28, page 67). The diverter valve must be mounted with
the waste connection facing upward.
7. Tighten the finger-tight knurled screw that attaches the rear cable to the mounting
block (→ Fig. 30, page 68).
8. Tighten the finger-tight knurled screw that attaches the rear cable to the diverter valve
and connect the grounding cable from the rear cable to the ground cable screw and
tighten the screw (→ Fig. 29, page 68).
