To ensure the Redi-Flo Variable Performance Pumping system operates properly, follow these guidelines:
• The Redi-Flo2® or Redi-Flo4™ pump must be installed vertically with the discharge end pointed upwards.
• The electrical voltage supply to the Redi-Flo VFD must always be or - 10% of the specified power
supply ( 103.5 - 126.5 VAC at 115V connection or 207 - 253 VAC at 230V ).
• For best performance when operating on a generator, 115V generators should be set at 120V without load and
230V generators should be set at 240V without load. Use a separate meter to set voltage; do not rely on built-
in meters found on generators. Verify generator voltage stays within tolerance at full load.
• The pump and motor must always be completely submerged in fluid to ensure
lubrication and cooling of the motor.
• The temperature of the fluid being pumped should be according to the technical
specifications shown in the motor specifications.
• The installation depth of the pump should always be at least three feet below the maximum drawdown level
of the well.
• Redi-Flo pumps are not recommended for well development or pumping fluid
containing abrasives.
• Redi-Flo2® pumps are not recommended for continuous operation applications.
• The warranty of the Redi-Flo pumps will be void if other than the Redi-Flo VFD is used or if corrosive fluids are
pumped.
• The service life of dedicated Redi-Flo pumps may be compromised if the ambient water quality exceeds one or
more of the following values:
pH<5 DO>2 ppm H2S>1 ppm CL->500 ppm TDS>1000 ppm

When handling and operating the Redi-Flo Variable Performance Pump system, all environmental regulations
concerning the handling of hazardous materials must be observed. When the pump is taken out of operation,
great care should be taken to ensure that the pump contains no hazardous materials that might cause injury to
human health or to the environment.

If the pump is used to purge a well, start the pump at minimum speed and gradually increase to desired speed.
Redi-Flo products are not recommended for well development.
