8.2 Replacing spare parts.
There are some spare parts available for the ILVA20/MVT10.
These are shown in Section 10.
8.2.1 How to replace the impulse hoses
Follow the procedure as per Section 8.1.1, but replacing the hoses with new ones.
8.2.2 Replacing the two way manifold seals.
1. Ensure that the steam flow through the ILVA is isolated and the line pressure has returned to atmospheric
pressure and the temperature cooled.
2. Close the isolation valves on the two way manifold and open the bleed valves on the MVT10 to allow
the condensate to drain. (Consider where the condensate is going to drain to. A container placed under
the bleed valves to catch the condensate may be advisable).
3. Loosen the hose lock nuts and unscrew the hoses from the two way manifold.
4. Loosen and remove the four screws connecting the two way manifold to the ILVA20 body.
5. Carefully remove the manifold from the ILVA20.
6. Remove the old seals and clean surfaces, including the surface of the two way manifold.
7. Refit the two way manifold ensuring new seals are used. CAUTION: Do not use old seals.
8. Refit or replace the four screws and tighten incrementally in a diagonal sequence. Finish by going round
each screw anti-clockwise to tighten each to 20 Nm.
9. Refit the hoses and tighten using good engineering practice. Tighten the lock nuts.
10. Close the bleed valves on the MVT10.
11. To recommission, follow steps in Section 6.
