5. Direct (aim) the fire monitor (figure 4, item 1) to place foam/water at the base of the fire.

6. OPEN the cutoff valve (figure 4, item 2) for the desired monitor.

7. When operation is complete:

a. CLOSE the cutoff valve (figure 4, item 2) for the monitor.

b. CLOSE FM-13, F.F. TO F.M. CRSVR (figure 2, item 2), fire pump to fire main cross connect.
