Routine Maintenance Procedures and General Guidelines
To disassemble and reassemble the Evolve™ Process Columns follow the instructions below. Note:
after reassembling the Evolve™ Process Column ensure that the column does not leak by performing
a hydrostatic leakage test.
When assembling/dissembling attention should be paid to:
CAUTION! Column units are heavy and can roll
1.
Always use the correct size tools. A comprehensive tool kit is provided with the columns. See
table below.
2.
Ideally components should be used at room temperature (15-25°C). If not, take particular care
as thermal expansion or contraction may make components fit more tightly and thus be more
difficult to disassemble.
3.
Dismantled assemblies should be rested on a clean, dry surface.
4.
Pay particular care not to damage the edge of the flow cells.
5.
When unpacking columns be careful not to scratch the inside of the acrylic column tubes.
6.
Be careful not to damage stainless steel surfaces by bumping, knocking or scratching.
7.
Do not over-tighten components and use correct torque settings as given in this guide.
8.
Good engineering practices should always be followed, and operations carried out in an approved
and safe manner.
