Pentair SHURFLO 5321 Series Installation And Operation Manual page 5

INSTALLATION AND OPERATION
ELECTRICAL
Electrical wiring should be performed by a qualified electrician,
in accordance with all local electrical codes.
The pump should be on a dedicated (individual) circuit,
controlled with a double pole switch (U.L./C-UL certified) rated
at or above the fuse ampere indicated by the pump motor label.
Depending on distance of the power source from the pump and
ampere load on the circuit, wire may need to be heavier than
indicated by the chart.
All 115 VAC and 230 VAC pump motors and systems MUST be
grounded per local and state electrical codes.
Improper duty cycle and/or rapid start & stop conditions may
cause the internal thermal breaker (if equipped) to trip, or can
result in premature motor failure due to excessive heat. Refer
to the pumps Product Data Sheet.
For the pump to meet U.L./C-UL requirements the circuit MUST
be protected with a slow-blow fuse (U.L./C-UL certified) or
equivalent circuit breaker as indicated on the motor label. Use
an approved wire of the size specified or heavier.
Circuit protection is dependent on the individual
application requirements. Failure to provide proper overload /
thermal devices may result in a motor failure, which will not be
covered under warranty.
