Pre-set pilots as noted:
Opening and Closing Speed
– Prior to pump start, actuate manual operator on solenoid to enable diaphragm assembly to stroke
open and closed. Observing the limit switch stem indicator, monitor rate of opening and closing speed. Adjust accordingly per applica-
tion requirements.
Note: Cycle diaphragm multiple times to confirm rate of movement and remove excess air trapped within the cover chambers (See
Figure 1 Below).
To increase the rate of opening/closing, turn the adjustment screws on the speed controls OUT, counterclockwise. In decrease the rate
of opening/closing, turn the adjustment screws on the speed controls IN, clockwise.
