Preventive maintenance is performed to keep equipment in proper working order. When
periodically performed, preventive maintenance will result in longer life for the
equipment and will reduce time lost due to equipment failure.
34.1 Cleaning
After each fermentation or cell culture run, remove any dirt from the fermentor
console, wiring cables and connectors.
Use a clean, dry, lint-free cloth or a dry brush to clean the outside of the
fermentor. If necessary, wipe any headplate parts with a clean cloth saturated
with water. The vessel may be scoured and flushed clean,
but do not use steel
wool to clean the vessel.
To maintain better life from O-rings and gaskets, be sure all surfaces are clean
and that gaskets and O-rings are wiped clean before reassembling filter covers,
fermentor tops, vessel and all gasket openings. A
light coat of silicone grease
should be applied to all O-rings before reassembling.
34.2 Vessel Removal
The procedure to remove the vessel mirrors the installation procedure—in reverse
order, with these very important exceptions: disconnect power to the fermentor
and close the port steam valve located on the side panel before you do anything
else toward disconnecting the vessel from the console.
34.3 Three-Month Intervals
Perform the following checks and inspections every three months:
CAUTION!
Always disconnect power to the fermentor and ensure that
the port steam valve is closed
before attempting to remove
the vessel from the console.
