WWAARRNNIINNGG::
Do not touch any circuit board, power device or electrical
connection before you first ensure that power has been
disconnected and there is no high voltage present from this
equipment or other equipment to which it is connected. Electrical
shock can cause serious or fatal injury. Only qualified personnel
should attempt the start–up procedure or troubleshoot this equipment.
WWAARRNNIINNGG::
Be sure the system is properly grounded before applying power.
Do not apply AC power before you ensure that grounds are
connected. Electrical shock can cause serious or fatal injury.
WWAARRNNIINNGG::
Do not remove cover for at least five (5) minutes after AC power is
disconnected to allow capacitors to discharge. Electrical shock can
cause serious or fatal injury.
CCAAUUTTIIOONN::
Disconnect motor leads (T1, T2 and T3) from control before you
perform a “Megger” test on the motor. Failure to disconnect motor
from the control will result in extensive damage to the control. The
control is tested at the factory for high voltage / leakage resistance
as part of Underwriter Laboratory requirements.
CCAAUUTTIIOONN::
Do not connect AC power to the Motor terminals T1, T2 and T3.
Connecting AC power to these terminals may result in damage to

QUICK START GUIDE
21
QQUUIICCKK SSTTAARRTT GGUUIIDDEE
To operate the Redi-Flo VFD system, simply:
1. Submerge the RF2 or RF4 pump in the water to be pumped.
2. Connect the motor lead to the Redi-Flo VFD. (Note: With RF4 Variable Performance
Pumps you must have an adapter cord to connect to Redi-Flo VFD.
3. If using a generator, start the generator and allow it to warm up.
4. If the generator has a circuit breaker, close the breaker and check the output
voltage from the generator. The output voltage must be within the specified
ranges (refer to Technical Specifications, at the end of this manual) to ensure proper
operation and prevent damage to the system. If the voltage is too high or too low,
adjustments to the generator must be performed to allow the system to run.
5. Plug the Redi-Flo VFD into a generator or connect to utility power supply. The unit
accepts 115V or 230V sources. Refer to the Input Power Terminals section for wiring instructions.
6. The VFD will initialize and be ready to drive the motor. After the initialization screen
appears, the following will be displayed:
• STP means the drive is stopped
• V indicates motor volts
• REDIFL2 indicates Redi-Flo2 pump mode
• LOC means the drive is in Local Keypad Mode
• A indicates motor amps
• HZ indicates motor frequency
The VFD defaults to Redi-Flo2 operation. To change to Redi-Flo4 press the sequence SHIFT-▼-SHIFT keys.
Use sequence SHIFT-▲-SHIFT to return to Redi-Flo2.
7. Press the FWD key to start the motor and use the ▲ and ▼ arrow keys to increase
or decrease speed. Continuous holding of the arrow key will increase the rate of speed
change. The STOP key is used to stop the motor.
8. Pressing the ENTER key allows the user to quickly set the speed to any given value
by using the ▲ and ▼ arrows to change speed and the SHIFT key to cursor between digits.
9. When powering down, unplug the Redi-Flo VFD from the generator BEFORE
removing the motor lead from the Redi-Flo VFD or turning off the generator.
Your Redi-Flo Variable Performance Pump system should contain the following
components:
1. Redi-Flo Variable Frequency Drive, (See Figure 1)
2. Either a Redi-Flo2® pump and motor with lead (Figure 2) or a Redi-Flo4™ Variable
Performance pump, motor, lead, lead/plug and RF4 x VFD adapter cord (Figure 3).
When connecting the discharge pipe or tubing to the pump, a back-up wrench should be used. It is
recommended that a safety cable be attached to the pump (using special brackets and cables, sold separately)
anytime plastic pipe or flexible tubing is used (as shown if figure 6). A check valve may also be added to
Redi-Flo2® pumps to prevent fluid from flowing back into the pump after it is turned off (backflow prevention).
A check valve is standard on Redi-Flo4™ pumps. Always check to ensure joints are fastened securely. The use of
a torque arrestor is not required when using the Redi-Flo VFD.
Make sure the electrical motor leads are not cut or damaged in any way when the pump is being lowered into the
well. Do not use the motor leads to support the weight of the pump. To protect against surface water entering the
well and contaminating the well, the well should be finished off utilizing a locally approved well seal.
The motor lead should be secured to the discharge pipe or tubing at frequent intervals to prevent sagging,
looping and possible motor lead damage. Teflon® wire ties are recommended for environmental applications.
IIMMPPOORRTTAANNTT
Plastic pipe and tubing tend to stretch under load. This stretching must be taken into account when securing the motor lead
to the riser pipe or tubing. Leave three to four inches of slack between clipped points. This tendency to stretch will also affect
the calculation of the pump setting depth. When plastic pipe or tubing is used, it is recommended that a safety cable be
attached to the pump to raise and lower it. Redi-Flo4™ pumps are designed to accommodate this cable and Redi-Flo2®
pumps can be fitted with a safety cable bracket (part number 1A0019).

ASSEMBLING THE REDI-FLO VFD SYSTEM
15
OOPPEERRAATTIINNGG CCOONNDDIITTIIOONNSS
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 within + 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 builtin 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
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.
PPuurrggiinngg AA WWeellll
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.
