ELECTRIC CONNECTIONS
All wiring, electrical connections, and system grounding must comply with the National Electrical Code
(NEC) and with any local codes and ordinances in force within the country of installation. Employ a
licensed electrician.
Confirm correct pump rotation. Standard 3VR, 5VR, and 9VR should rotate clockwise when viewed
from above.
Install an all-leg electrical power disconnect switch near the pump.
Disconnect and lockout electrical power before installing or servicing the pump.
Electrical supply MUST match pump's nameplate specifications. Incorrect voltage can cause fire, damage
motor and void the warranty.
Motors without built-in protection MUST be provided with contactors and thermal overloads for single phase
motors, or starters with heaters for three phase motors. See motor nameplate. Use only copper wire to
motor and ground. The ground wire MUST be at least as large as the wire to the motor. Wires should be
color coded for ease of maintenance. Follow motor manufacture's wiring diagram on the motor nameplate
or terminal cover carefully.
Avoid any contact of the electric cables with the pipes or other parts of the pump. Carefully insulate the
cables against humidity.
