23. Operating

24. Starting Checks 1 Check the system is correctly opened up from the Sea tube to the Aft BKD. 2 Shut 3x Module Vv’s. 3 Place VK120 in the operating position. Place VK121 is in the Sea Water position.

25. Starting Checks 4 Ensure the plant dosing pump is switched on. Drain the cleaning tank VK111. 5 Check that the LP Feed Vv (behind the cartridge filters) is open. 6 Open the Discharge to Bilge until Conductivity is below 2000µS.
