Routine Maintenance ProceduresGeneral guidelines To disassemble and assemble the columns follow the instructions below. After reassembling the column ensure that the column does not leak by performing a hydrostatic leakage test.

When assembling/dissembling attention should be paid to: 1. Always use the correct size tools. A comprehensive tool kit is provided with the columns. See Table below.

2. Ideally components should be at approximately room temperature (approximately 20° C). If not, take particular care as thermal expansion or contraction may make components fit more tightly and thus 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 flowcells 5. When unpacking column components and kits be careful not to scratch the inside of the 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 be followed at all times and operations carried out in an approved and safe manner.

9. Components of the Evolve® are heavy and an overhead hoist MUST be used to remove the adjuster unit. Further guidance is given in operating manual. ALL operations must be performed by two people.

Fitting Instructions Removal of tube from column 1. Use the instructions in the main operating manual to remove the adjuster cell assembly from the column.

2. Attach the spare set of eye bolts provided with the original column, to the top tube flange 3. Using appropriate lifting slings or equipment attach the hoist to the eye bolts.

4. Identify column components using the schematic diagram shown below.

5. Using the correct Allen Key carefully remove top tube flange by removing the tube support rod bolts.

6. Retain the bolts and place the flange on a horizontal clean surface.

7. Remove the top tube seal from the flange and the tube buffer seal and discard 8. Lift out tube from the bottom flange, remove bottom tube seal and buffer seal and discard.

9. Lift the column tube unit away from the column base unit and move over the maintenance blocks. Slowly start to lower the unit when approximately 5cm above the maintenance blocks PAUSE and check position of the blocks 10. When maintenance blocks are in the correct position, ensure that access can be gained to the tie bar fixing bolts.

11. continue to lower the column unit until the unit rests on the blocks and hoist slings are slack.

13. Loosen the column bottom tie bar bolts using the socket adjuster. Remove tie bars by manually twisting the bars. (Figure 6b). Retain the tie bars and bottom fixing bolts.

14. Remove the bottom buffer seal from its location (Figure 7a) and slide it up the tube so it is clear of the flange shield ring. It is now possible to remove the tube.

NOTE: TWO PERSON OPERATION 15. Two people should stand opposite each other and using correct lifting techniques, lift the column tube out of the flange shield ring. (Figure 7b). Discard the tube and buffer seals.

16. When tube is removed, and moved clear of the maintenance area, lift out flange shield ring complete with tube seal and discard. Retain the stainless steel flange. (Figure 7c).

Step 2-Reassembly of the Tube unit.

In the tube replacement kit, the tube is supplied ready for assembly with scale label, Evolve®label and rating plate and buffer seals on the tube wall.

Ensure the column bottom flange is located on the maintenance blocks and the blocks are evenly spaced but do not obscure the tie bar fixings Insert the flange shield ring into the stainless steel column flange. (Figure 8a)

1. Identify the location of the alignment indicator as this will assist in orientating the tube correctly.

2. Identify the replacement bottom flange shield ring and locate into the bottom flange.

(Figure 8b) 3. Fit the column bottom tube seal into the seal groove in the column flange shield ring.

Ensure this seal is located completely within the groove. (Figure 8c and Figure 8d) 4. The buffer seals should be in place on the outside diameter of the tube at a distance approximately 2cm from each end of the tube.

5. Before lifting the tube into place ensure the tube is orientated correctly. The correct orientation is that the scale label should be at the front of the column perpendicular (90O) from the alignment indicators on the side of flange. See Figure 9 below.

Figure 9 Orientation of tube unit relative to alignment indicators 6

6. Two Person Operation Lift and locate the acrylic tube. Ensure it is located centrally and evenly within the shield ring. (Figure 10a) 7. Locate and secure tie bars on the bottom flange using the bottom fixing bolts. Initially hand tighten the bolts, working diametrically opposite. When complete, use the torque wrench (set to 50Nm) tighten the tie bar bolts, working diametrically opposite.

8. Using the hoist, lift the top column flange (Figure 10b). A top column tube seal is provided and although this seal is not process wetted it can be replaced. To do so place the flange on a flat surface, remove lifting eyes and invert. Remove seal and replace.

When complete turn over the top flange and reattach lifting eyes. Re attach hoist and move over tube unit.

9. Place the flange over the tube unit so that the top fixing bolts can be engaged. Ensure alignment indicators are positioned correctly.

Figure 10 Reassembly of Column Tube Unit 10. Lower the top flange (Figure 10c) and secure the bolts by hand but do not tighten the bolts.

11. Locate the upper and lower buffer seals into the bottom flange and underside of the top column flange.

12. Using the torque wrench (set to 50Nm) tighten the tube support rod bolts located in the top column flange.

13. Recheck the bottom fixing bolts and tighten if necessary.

Column Reassembly and Preparation For Use Note: Reassembly of the column is the reverse of disassembly and starts from column bottom upwards. Each sub assembly is reassembled before attached to the column.

Step 1 – Assemble Tube Unit onto the Column base and Bottom flowcell.

1. Attach appropriate lifting slings to the eye bolts located on the tube unit flange. Lift the tube unit.

2. Move the tube unit over the fixed end assembly. (Figure 11a)

3. Align the tube unit using the alignment indicators. (Figure 11b) 4. Replace the bottom column flange bolts/washers in the tube unit.

5. Slowly lower the tube unit and use the column bottom flange bolts to align the tube unit onto the bottom flange.

6. When tube unit is in place on column base, locate the column bottom flange nuts, initially, hand tighten, working diametrically opposite to ensure equal loading on the seal.

Then using the correct spanner working diametrically opposite to tighten.

7. Remove the eye bolts from the top flange and store with other column tools.

8. Attach appropriate lifting slings to the eye bolts located on the adjuster assembly. Lift the adjuster assembly.

9. Move the assembly over the column unit. Use alignment indicators to line up the adjuster. Slowly, position the adjuster unit into the column tube (Figure 11c). Alignment pins located in the top flange are provided to assist positioning. (Figure 12a).

CAUTION

10. Locate the top flange fixing bolts/washers, initially, hand tighten, working diametrically opposite to ensure equal loading. (Figure 12b). Then, using the correct spanner working diametrically opposite to tighten fully.

11. Remove lifting slings, (Figure 12c). Column has been successfully assembled and ready for hydrostatic leak test and return to operation.

It is advisable to perform a Hydrostatic Leak test before the column is used.

Hydrostatic Leak Test The purpose of this test is to check that there are no leaks from the column and the column is ready to use. Due to the materials of fabrication, when the column is initially exposed to pressure the column will flex. It is necessary to perform the hydrostatic leak test using a two-step procedure.

1. Fill the column with WFI or high quality water and position the adjuster at the operating bed height.

2. Ensure the adjuster seal is wetted with buffer or other suitable liquid prior to assembly. This helps ‘lubricate’ the seal to ensure correct seating.

3. Activate the adjuster seal 4. Ensure all air is removed from the column and any connections.

5. Attach a calibrated pressure gauge to the top inlet of the column 6. Raise the column pressure until 1bar (15 psi) and close bottom inlet valve . Wait 15mins for the pressure to stabilize.

7. Open the valve and increase the pressure to maximum working pressure 3bar (43.5 psi).

8. Wait 15mins for the pressure to stabilise. Check the pressure and ensure pressure is 3.0bar (43.5psi).

9. Wait for 15mins.

Due the nature of materials it is likely there will be a small pressure drop however, this should not exceed 0.2 bar.
