12 CP-Series Submersible Motors Installation, Operation and Maintenance Manual
VI. Pre-Installation
1. Maximum Water Temperature:
A) Standard Version: 30° C (86° F)
Must maintain flow rate of .75 fps (5 - 10 HP), 1.0 fps (15 - 30 HP), 1.75 fps (40 HP and greater). For
temperatures above 30° C (86° F), motor output must be reduced to ensure
correct cooling: maximum temperature allowed is 35° C (95° F).
B) HT Version: 45° C (113° F)
Must maintain flow rate of .75 fps (5 - 10 HP), 1.0 fps (15 - 30 HP), 1.75 fps (40 HP and greater). For
temperatures above 45° C (113° F), motor output must be reduced to ensure
correct cooling: maximum temperature allowed is 60° C (140° F).
2. PH content of the water between: 6.5–8
3. Maximum Chlorine Content: 500 PPM
Maximum Sulfuric Acid Iron Content: 15 PPM
Maximum Flourine Content: 0.8 PPM
Maximum Electric Conductivity: 118 μMHO/INCH
4. Maximum Sand Content: 50 PPM
5. Proper approved three phase overload protection. Class 10, quick trip overloads are mandatory.
See Tables 1 - 4, 9 or 10.
6. Proper fusing for motor circuit protection. See Table 5.
7. Proper Line Voltage During Running Conditions:
460V ±10%, i.e. 506 to 414 volts
230V ±10%, i.e. 253 to 207 volts at 60 cycle system at motor lead wire terminal. (Voltage drop of cable
should be considered by user.)
Combination of Voltage and Frequency Variation: ±10% (sum of absolute values of voltage and frequency).
Phase Unbalance: ±5% (3 phase)
8. Proper sizing of motor (current, thrust, voltage, etc.) and a 10 feet clearance from the bottom of the well are
required.
9. In the case of horizontal installation, the motor is to be rigidly aligned with the pump and firmly mounted to
prevent any load on the shaft and bearings and to avoid any damaging vibrations to the motor. Also, see #8
in Section IV.
10. The maximum depth of immersion for all motors is 1,150 ft (350 m).
11. The power cables shall be sized large enough so that at rated current there will be less than a 5% voltage
drop. Cables must be waterproof submersible type.
12. For 3Ø motors a balanced and properly sized transformer bank shall be provided. Improper electrical supply
(for example, phase converter, V-connection transformer, etc.) or connections will void the warranty.
13. Single phase protection is recommended for protection of the installation. Any failure due to single phasing
of the incoming voltage causing the motor to fail will void the warranty.
14. Lightning arrestors are recommended in the interest of protecting the control panel, as well as the insulation
system of the motor. Any motor failure due to lightning or other Acts of God will void the warranty.
15. Provide waterproof insulation splices between all lead wires and well cables.
16. In the event that a reduced voltage starter is used to start the motor, the following should be verified:
A. Correct quick trip ambient compensated overloads are incorporated.
B. Proper short circuit protection is utilized.
C. The torque required by the motor and pump package is attainable by this type starter.
