Suction Piping - Franklin Electric I Serie Manual De Instalación, Funcionamiento Y Mantenimiento

READ AND FOLLOW SAFETY INSTRUCTIONS
This is the safety alert symbol. When you see
this symbol on your pump or in the manual, look
for one of the following signal words and be alert
to the potential for personal injury:
warns about hazards that will cause
D A N G E R
serious personal injury, death or major
property damage if ignored.
warns about hazards that can cause
WA R N I N G
serious personal injury, death or major
property damage if ignored.
warns about hazards that will or can
C AU T I O N
cause minor personal injury or major
property damage if ignored.
The label NOTICE indicates special instructions, which
are important but not related to hazards.
Carefully read and follow all safety instructions
in this manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
Wire motor for correct voltage.
Ground motor before connecting
to power supply.
HAZARDOUS VOLTAGE Can shock, burn
WA R N I N G
or cause death. Ground pump before
connecting to power supply. Disconnect
power before working on pump,
motor or tank.
Engineering Data:
Maximum Liquid Temperature:
212 °F (100 °C) – standard seal or packing
Maximum Working Pressure (fluid temperature dependent):
• NPT connections, 250 pounds per square inch (psi)
• Class 150 ANSI flanged connections, 250 psi
Maximum Suction Pressure: 100 psi
Starts per Hour: 20 MAX, evenly distributed.
Installation Location:
• Locate the pump as near liquid source as practical,
below level of liquid for flooded suction, and
automatic re-priming capability.
• Allow adequate space for servicing and ventilation.
Protect the unit from weather and water damage
due to rain, flooding or freezing temperatures.

Wiring And Grounding
Install, ground, and wire according to local and
National Electrical Code requirements.
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 manufacturer's wiring diagram on the
motor nameplate or terminal cover carefully.
This equipment must not be used by children or
WA R N I N G
persons with reduced physical, sensory or mental
abilities, or lacking in experience and expertise,
unless supervised or instructed. Children may not
use the equipment, nor may they play with the unit
or in the immediate vicinity.

INSPECTION
All equipment is inspected at the factory prior to shipment.
However, you should inspect all equipment upon arrival for
shipping damage and item shortages from the packing slip.
Report any damage or shortages to the carrier.
INSTALLING PUMP
Ensure that all foreign material has been removed from the pump
before mounting. Be sure to remove all shipping protection prior
to operation.
NOTICE: Many of the pumps may be shipped with protective
guards and coatings.

SUCTION PIPING

For best performance the suction piping should be at least as large
as the pump flange, never smaller and ideally, at minimum, one
size larger. Use an eccentric reducer at the suction flange with the
straight side mounted up. The use of flow-retarding fittings is to be
avoided and, if necessary, should never be placed closer than four
times the pipe diameter to the pump suction. The pump should
be at the highest point of the piping. Slope the piping up to the
pump to prevent air pockets and avoid changing pipe size with the
exception of the eccentric reducer mentioned above. All suction
piping and fittings are to be checked for any foreign material (rocks,
bolts, wire, etc.) and also any sharp burrs that could disrupt the flow.
