Electrical Work
Before beginning installation procedures, these installation and operating instructions should
be studied carefully. All electrical work should be carried out by a qualified electrician in
accordance with the latest edition of the National Electrical Code(NEC), local codes and
regulations.
Adherence To Environmental
Regulations
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.
Returning a Pump for Service
Only pumps that are certified as uncontaminated will be accepted by GRUNDFOS for
servicing. GRUNDFOS must receive this certification prior to receiving the pump. If not,
GRUNDFOS will refuse to accept delivery of the pump. In these cases, all costs incurred in
returning the product to the customer will be paid by the customer. Contact your distributor
for details on returning Redi-Flo products for servicing.
Electrical Hazards
The Redi-Flo Variable Performance Pump system is not approved for Class 1, Division 1,
Group D locations as specified by the National Electrical Code (NEC). Consult local authorities
and regulations if you have any doubt about its suitability for a specific application.
WARNING
Hazard of Electric Shock: Do not expose the Redi-Flo Variable Frequency Drive
(VFD) to moisture. If unavoidable exposure to moisture occurs, disconnect the
electrical supply power immediately and have the unit inspected by an authorized
service center to insure all safety features of the unit are in tact. To reduce the
risk of electrical shock during operation of this Redi-Flo product, extreme care
should be taken to ensure adequate grounding. All Redi-Flo products are provided
with grounding provisions which comply with NEC guidelines. Always verify power
source is properly grounded and there is a solid ground connection between the
power source and the Redi-Flo VFD before energizing. If the means of connection
to the supply power source is other than grounded metal conduit, ground the Redi-
Flo VFD back to the service by connecting a copper conductor, at least the size
of the circuit supplying the Redi-Flo VFD, to the grounding screw/terminal provided
within the wiring compartment of the Redi-Flo VFD.
