PRE-INSTALLATION CHECKLIST
ASSEMBLING THE REDI-FLO VFD SYSTEM
SAFETY WARNING
All electrical work should be performed by a qualified electrician in
accordance with the latest edition of the National Electrical Code,
local codes and regulations.
To operate the system you will also need:
1. A discharge hose or pipe to connect to the pump (See Figure 4).
2. An electrical plug to connect the Redi-Flo VFD power cord to your portable
generator may be needed if the supplied plug is not compatible with your generator
(See Figure 5).
3. Safety cable and hardware for lowering and lifting the pump (See Figure 6).
Figure 6
The exact type of plug used will depend
upon your generator, The Redi-Flo VFD
is supplied with a standard NEMA, 115V,
3 prong plug.
Unpack the components of the Redi-Flo Variable Performance System. With Redi-Flo2®
pumps, the pump will be packed in the center of the motor lead spool as shown on page 6,
Figure 2. Make sure that you have the correct pump for the installation. If you purchased a
Redi-Flo4™ pump in component form, see instructions on pages 25-26, and refer to the Redi-
Flo4™ Installation guide for assembly instructions.
Attaching the Pump to the Pipe
When connecting piping to the pump, a back-up wrench should be used. Redi-Flo4™ pumps
should only be gripped by the flats near the top of the discharge chamber. Under no
circumstances grip the body of the pump, cable guard or motor. When tightened down, the
threaded end of the first section of riser pipe or nipple must not come in contact with the check
valve retainer in the discharge chamber of the pump. After the first section of pipe has been
attached to the pump, the safety cable should be connected to the pump(as shown if figure
6). Do not clamp to the pump. When raising the pump, be careful not to place bending stress
on the pump by picking it up by the pump end only. A safety cable should be attached to the
pump (using special brackets and cables, sold separately) anytime plastic pipe or flexible
tubing is used. 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.
