Before you start
- Obtain the AUX Key through the control-room sequence.
- In the AUX room, retrieve the floppy disk from the cabinet and read it on the computer.
Give me a small hint
The symbols show lever orientation. The white marks identify a line; painted arrows tell you which way to read it.

LINE 1
LINE 2
LINE 3
Step by step
- For line 1, start by the lower arrow on the cabinet wall. Follow only pipes marked with one white stroke.
- For line 2, start by the middle arrow on that same wall. Follow pipes marked with two strokes.
- Line 3 starts on the opposite wall, above line 2’s indicator. Follow the three-stroke markings.
- Apply each sequence below in its painted-arrow direction. A vertical bar means vertical; a dash means horizontal.
- Check for three green indicators, then return to the control room.
How you know it worked
Each correctly set line changes its indicator to green.
Next move
Resume the remote-system commands in the control room.
Still stuck? Puzzle spoilers
- Do not read the room as three straight horizontal rows: follow the painted pipe markings.
- Line 3 begins on the opposite wall. Starting all three at the cabinet produces the wrong order.
