WARNING The installer is required to reset the “Max. RPM setting” to position 2, illustrated
below. Failure to perform this adjustment may cause damage and will void the warranty.
The
ETAPUMP

SunCentric P
pumps is manufactured for a variety of
solar pumps.
SunCentric P
applications require this change from the standard factory setting.
How to reset the Maximum RPM
setting
1. Remove the bottom end of the EP-600A controller enclosure (the end with the conduit openings)
2. Locate the adjustment knob shown in the photo below (circled)
3. In most cases, the knob will be at the standard factory setting full clockwise. Turn it counter-clockwise
to the ink mark illustrated as #2 in the illustration below. The exact position may vary from this
illustration. Follow the ink marks in the unit.

[ ____ ]
You can reduce the maximum RPM further if you desire to limit the peak flow rate to less than this
normal setting. This will only reduce the flow in high-sun conditions. It will not influence low-light
performance. Turning the control counterclockwise from position 2 allows reduction in pump speed down
to about 50%.
