Before starting
a program
At the end
of a program
Carry out a visual check before starting every program:
- Is everything correctly loaded/connected for cleaning?
- Can the wash water consistently permeate wash items with 2 open-
ings, such as pipettes and viscometers?
- Are the spray arms clean and do they rotate freely?
- Is the filter combination clean?
Remove any coarse soiling and clean the filter combination if nec-
essary.
- Is the mobile unit correctly connected to the water supply?
- Are the removable modules, nozzles, irrigation sleeves, and other
rinsing fittings securely connected?
- Are all process chemical containers sufficiently filled?
The following must be checked at the end of every program:
- Are the nozzles and connectors securely held in position in the mo-
bile unit, module, or insert?
- Are all lumened wash items still attached to the appropriate noz-
zles?
- Have any of the wash items on the load carriers moved during
cleaning?
If any of the wash items move during cleaning, this can have a neg-
ative effect on the wash result.
Assess whether wash needs to be repeated: for example, if petri
dishes have overturned or glass beakers have fallen over.
- Carry out a visual check of the wash items for cleanliness.
- Can wash water access the insides of wash items with 2 openings?
- If the machine is equipped with a drying unit, carry out a visual
check of the wash items for dryness.
