if necessary, according to the following instructions:
1) Remove the Cap from the E.P.R. Access Valve, and connect a pressure gauge (The
E.P.R. needs no adjustment if the pressure gauge shows 22 PSIG for F-2000MLF.)
2) Remove the Cover from the E.P.R., and rotate the Adjustment Screw by a hexagon
wrench until the pressure gauge shows 22 PSIG (F-2000MLF). Rotate clockwise to
increase the pressure setting, and rotate counterclockwise
