Important Safety Instructions
SAVE THESE INSTRUCTIONS - This manual contains
important instructions that should be followed during
installation, operation, and maintenance.
This is the safety alert symbol. When you see this
symbol in this manual, look for one of the following
signal words and be alert to the potential for personal
injury!
indicates a hazard which, if not avoided, will
result in death or serious injury.
indicates a hazard which, if not avoided,
could result in death or serious injury.
indicates a hazard which, if not avoided,
could result in minor or moderate injury.
NOTICE
addresses practices not related to
personal injury.
Carefully read and follow all safety instructions in this
manual.
Keep safety labels in good condition. Replace missing
or damaged safety labels.
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
6.2 Testing
ELECTRICAL
(See Table 1, Page 4, for Motor Electrical
Specifications)
1.
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.
2. Inspect the motor to determine that it is the correct
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.
3. On all new installations and after the motor has
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.
4. Fuses or circuit breakers and overload protection
are required. Fuses or circuit breakers and
overloads must be sized in accordance with National
Electrical Code (NEC) or Canadian Electrical Code
(CEC) requirements, as applicable, and with all
applicable local codes and ordinances. See
Section 6 for these specifications.
5. Wire and ground the motor in accordance with
National Electrical Code (NEC) or Canadian
Electrical Code (CEC) requirements, as applicable,
and with all applicable local codes and ordinances.
6.3 Storage and Drain/Fill Instructions
LIFTING
1.
Heavy Object. Lifting equipment must be
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.
