California Proposition 65 Warning
This product and related accessories
contain chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm.
APPLICATION LIMITS
Maximum Immersion Depth: 985 ft. (300 m)
Maximum Water Temperature: 95°F (35°C)
pH content of the water: 6.5–8
Minimum Cooling Flow Rate: 0.5 feet per second (fps)
(0.15meters per second (mps)).
Required line voltage at the motor under operating
conditions (±10%).
NOTICE When calculating voltage at the motor, be sure
to allow for voltage drop in the cable.
The sum of the absolute values of the voltage and
frequency must not vary from the sum of the nominal
values by more than ±10%.
Operating with current unbalanced on the three legs of
the circuit can overheat and damage the motor and will
void the warranty. Current imbalance must not exceed
5% maximum.
Maximum Sand Content: 50ppm (max. size 0.1–0.25mm)
Maximum Chlorine Ion Content: 500ppm

capable of lifting motor and attached equipment. Check
over all tools, especially the hoisting gear, for wear or
damage before hoisting the unit.
2. If the total length of the pump and motor unit (without
any riser pipe attached) exceeds 10ft (3m), support the
unit with a girder while hoisting (see Figure 1). Do not
remove the supporting girder until the unit is standing
vertically in the hoist. Check for damage.
Risk of electrical shock if the cable is
damaged. Inspect the motor cable for any nicks or
cuts. Do not use the motor cable to pull, lift, or
handle the motor. Protect the motor cable during
storage, handling, moving, and installation of the
motor.
horsepower, voltage, and size for the job and that
there is no shipping damage. Verify that the motor
nameplate voltage matches the available power
supply voltage. The nameplate rated voltage must
not vary more than ± 10% from the power supply
voltage.
sat idle for a long period of time, check the motor's
internal electrical resistance with a megohmmeter
with lead wires connected. Prior to installation, the
motor should have an insulation value of at least
500 megohms. After installation, the motor and
power cable should have a minimum insulation
value of 1 megohm. If the minimum values are
below the listed values, contact the factory before
starting the motor.
