Shutdown
It is recommended to shut down the Wellwash Versa at the end of the
day.
1. Remove any plates still in the instrument.
2. Empty the wash bottle(s) and fill them with deionized distilled
water. Then prime the instrument.
3. Rinse the liquid system with deionized distilled water to remove any
buffer solution from the liquid tubing and wash head. The rinsing
procedure should be performed if the instrument is left to stand or is
switched off at the end of operation.
If the instrument will be left to stand for a short time during the
same day, the wash head can be immersed in wash buffer or
deionized distilled water. Refer to "Soak wash head" on page 92 and
"Move wash head" on page 93.
Caution If the wash heads are not rinsed, the tips may become clogged.
If this occurs, the wash heads will need to be cleaned, repaired or may
have to be replaced.

4. If the instrument will be left to stand for a longer time, priming
must be performed to remove all liquid from the system. For this
purpose, remove all tubes from the liquid bottles. Prime the
instrument without liquid to empty all liquid from the system.
5. Switch off the instrument.
6. If you have spilled infectious agents on the instrument, disinfect
with 70% ethanol or another disinfectant (see "Decontamination
procedure" on page 122).
7. Finally empty the waste bottle.
Warning The wash heads and priming vessel may be infectious after the
instrument has been used. ▲
