A. Test of the Valve 12QM
(1) In the test that follows, on each operation of the LP valve:
-
make sure that the see/feel indicator operates smoothly, from the valve open (valve closed) position to the valve closed (valve open) position
-
make sure that the see/feel indicator marks are accurately aligned in the valve open position
-
make sure that the see/feel indicator marks are at 90 degrees to each other in the valve closed position.
