Preparing for Column Use

Step 1 - 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 components will
flex. It is important that the hydrostatic leak test is performed as outlined below following a multiple step operation.
1.
Fill the column with WFI (water for injection) 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.
Open the valve and increase the pressure until 2.0bar (29psi) and close bottom inlet valve. Wait 15mins for the
pressure to stabilize.
7.
Release the pressure in the column.
8.
Open the valve and increase the pressure until 4bar (58psi) and close bottom inlet valve. Wait 15mins for the
pressure to stabilize.
9.
Check the pressure and ensure pressure is 4 bar (58psi).
Due the nature of materials it is possible there will be a small pressure drop, however, this should not exceed 0.2 bar.

Step 2 - Levelling the 350mm Columns

The 350mm columns are fitted with height adjustable feet and a spirit level is provided. This enables the column to be
leveled or to increase ground clearance.
1.
Ensure the column is in the final process position and the column has been disconnected from any overhead hoist.
2.
Place the spirit level on the top surface on the column.
3.
Locate the flat portion on the column feet bolt and using the correct spanner adjust so that the bubble is located
centrally on the spirit level.
4.
Turn the spirit level by 90 degrees and repeat.
