6.2 Startup
6.2.1 Output Adjustment
When starting up the pump for the first time, it is best to set the stroke adjustment to
0% output and then slowly increase the setting to 100%. This allows you to react to
any leaks that may be present in the piping system before they become severe.
The
PulsaPro 900
uses a hand wheel for manual stroke adjustment. It is mounted on the
rear of the stroke adjust housing (refer to Figure 10). The hand wheel can be adjusted at any
point from 0 to 100%. It includes a stroke lock mechanism. Before making an adjustment
pull out the stroke lock handle and rotate it ¼ turn to hold it in the disengaged position. With
the stroke lock disengaged, crank the hand wheel in either direction to adjust the stroke length
to the desired setting – do not go below the 0% or above the 100% marks. After you have
completed your stroke length setting, re-engage the stroke lock by turning the stroke lock
handle ¼ turn.
Please be sure the stroke lock is then engaged during pump operation to prevent drift.
