Due to different tolerances in components and proportional valve coils, jump jacks JJ1 through
JJ6 (JJ1 through JJ3 affect side 1, JJ4 through JJ6 affect side 2) were added to allow adjusting
the SLOW flow rate. If the SLOW flow rate is too slow, adding a jumper on one of these jump
jacks will increase the valve drive output in SLOW flow mode. Each jumper added increases
the drive output (maximum 3 per hose outlet). They do not affect FAST (or full) flow. If
jumpers have been added and the SLOW flow is too fast (for example, over run of presets),
removing a jumper will decrease the drive output in SLOW flow mode.
