Calculating Cleaner Speed/Rpm - Pentair Racer Installation And User Manual

Calculating Cleaner Speed/RPM

1. To determine whether the RACER™ Pressure Side Pool Cleaner is receiving the proper water pressure,
turn off the pool pump, and carefully remove the cleaner from the pool.
2. Mark the front tire/wheel with a marker, such as a blade of grass stuck under the tire.
3. Have someone restart the pool pump and booster pump while you place the cleaner just beneath the
pool's water surface.
Note: Be sure to hold onto the sweep hose (if installed) to avoid getting wet, as flow will return to the
sweep hose regulator when the pump is restarted.
4. Count the number of full rotations made by the marked wheel over a period of one minute. The number of
rotations will give you the revolutions per minute; or RPM's.
Note: Be sure that the back-up valve isn't cycling at this time.
5. For proper performance, the RACER cleaner operates between 31 - 33 RPM's with a sweep hose
installed and 33 - 36 RPM's without a sweep hose.
If the RPM is below 31 with a sweep hose installed, or below 33 without a sweep hose, then call your
local Pool Professional or contact Pentair's Technical Support Department at 1-800-831-7133.
If the RPM is higher than 33 with a sweep hose installed, or higher than 36 without a sweep hose, at the
wall fitting adjust the valve, as described under "Setting the Water Flow to the Cleaner" on page 2, until
the RPM falls back into the optimal range.
