2. Carefully slide the magnetic insert out from the bottom port of the series CRS separator.

6.4.3 Drain the fluid

1. Wait for 10 minutes before flushing the separator.
1. Allows the residual magnetic field from the magnet insert to dissipate
2. Drains the magnetite and other contaminants during system flushing.
2. Open the skim valve at the top of the coalescing separator to release any trapped air.
3. Open the adjacent blowdown at the bottom of the series CRS separator to drain the
contaminants.
4. Use applicable equipment to drain the fluid.
5. Dispose of the fluid in accordance with local regulations.

6.4.4 Install the magnetic insert

1. Carefully open the upstream isolation valve nearest to the coalescing separator.
The flushing must continue until the system fluid runs clear.
2. Close the separator blowdown.
3. Close the skim valve.
4. Insert the magnetic insert into the separator.
5. Use a torque wrench to tighten the screws.
The torque must be 24.0 lbf.in +4.0 lbf.in / -0 (2.7 Nm +0.5 Nm / -0).
6. Open the upstream isolation valves.
7. Open the downstream isolation valves.

6.5 Service the air bleed ports or drain plugs

1. Remove the required component from the magnetic separator.
2. Clean the old thread sealant by using a wire brush.
3. Allow the separator and the component to dry.
If damaged, replace the component or separator.
4. Apply the 360° bead of Loctite 567
RectorSeal No. 5 pipe thread sealant for all non-glycol based applications or any PTFE
thread sealing tape must be used as sealant.
For more information, see Loctite handling precautions.
5. Install the component in the CRS.
6. Use a torque wrench to tighten the component.
7. Apply a 100 psi or less pressure on the assembled component.
