Check for Proper RPM
Before operating the Polaris
proper wheel revolutions per minute (RPM).
For maximum efficiency, the cleaner should
operate between 32 and 34 RPM.
1. Mark the single-wheel
side tire.
2. Turn pump on, hold cleaner
below water level and count
wheel revolutions for one minute.
If count is not in target range,
refer to Adjusting the Wheel RPM
in the Troubleshooting section for
more information.
Adjusting the wheel RPM:
• If an adjustable valve is installed on the cleaner line, open it completely so water
can flow freely to the Polaris
• Check the filter screen in the in-line filter for debris that restricts water flow.
• Clean the skimmer, filter and pump basket, clearing debris that restricts water flow.
• Check the hoses, connections and swivels for leaks that cause loss of water pres-
sure.
• Remove the blue restrictor disk from the UWF.
If count is more than 34 RPM:
• Replace the blue restrictor disk in the UWF with the red restrictor.
• If the flow is still too high, unscrew
the pressure relief valve until the proper RPM is reached.
Note:The pressure relief valve should only be adjusted when a restrictor is
installed.
