6. Priming

Warning!
Wear protective clothing, eye protection and gloves! Never press
down the piston when the closure cap is put on! Avoid splashing
the reagent! Liquid may accumulate in the closure cap. To avoid
splashes dispense slowly. Follow all safety instructions and observe
limitations of use and operating limitations (page 30-32).
Note:
Before using the instrument for the first time, ensure it is rinsed
carefully and discard the first few samples dispensed. Avoid
splashes.
6.1. Instruments with recirculation valve
1. Remove closure cap and open discharge tube (Fig. 1).
2. Set valve to ‚Recirculate' (Fig. 2).
3. For priming gently pull up the piston approx. 30 mm and push it
down rapidly until the lower stop. Repeat this work step until there
are no more air bubbles in the cylinder (Fig. 3).
4. Turn valve to ‚Dispense' (Fig. 4).
5. To avoid splashes when priming hold the discharge tube on the
inner wall of a suitable receiving vessel and dispense liquid to
prime the discharge tube until it is bubble-free. Wipe away any
remaining drops from the discharge tube (Fig. 5).
6.2. Instruments without recirculation valve
1. Remove closure cap and open discharge tube (see 'instrument with
recirculation valve', Fig. 1).
To avoid splashes, hold discharge tube orifice on the inner wall of
a suitable receiving vessel.
2. For priming pull up the piston approx. 30 mm and push it down
rapidly until the lower stop. Repeat this work step until there are
no more air bubbles in the cylinder (Fig. 3).
