If minimum values are not obtained, contact factory.5) C heck the tightness of drain plugs, mounting bolts and cableconnections.6) D o not hammer the shaft, coupling or slinger since this maydamage the thrust bearing. Check the rotation of the shaft byhand to insure that it turns freely.7) D o not drop the bottom end of the motor in the dirt or mudsince this may plug up the diaphragm opening.8) I f motor is to be installed in a horizontal position, make surethat the lead wires are at the 12 o'clock position when facingthe motor shaft (in horizontal position).TROUBLE SHOOTING OF SUBMERSIBLE MOTORS1) Motor does not start.• No power supply.→ Check for loose or corroded connectionsand motor lead terminals.• Defective connections. → Correct connections.2) Fuses or relay blow when motor starts.• Incorrect voltage. → Apply correct voltage (Nameplate).• Incorrect fuses or relay.→ Replace with proper fuses and relay.• Defective capacitors. → Replace with proper capacitors.• Wrong connections. → Correct wrong connections or shortcircuit.• Locked rotor conditions. →Correct pump or well conditions.• Insulation resistance down. →Check the line and correct.3) Motor runs for a while and then blown fuses or relay.• Low voltage or high voltage. → Apply rated voltage.• Defective capacitors. → Replace with proper capacitors.• Different control box for the motor. → Replace with propercontrol box.• Defective starting voltage relay. → Replace with proper relay.• Pump is sand clogged. → Pull pump and clean well.• Overheated protector. → Shield the control box from heatsource.The following conditions are stated to provide the owner with a listof criteria for maximum motor life and to assure motor warranty.PRE-INSTALLATION1) Maximum water temperature:A) 35°C( 95°F): 6" (5 40HP) motors.B) 25°C( 77°F): 6" (50,60HP), 8", 10", 12" and 14" motors.2) PH content of the water between: 6.5 -83) Maximum chlorine content: 500 PPMMaximum Sulfuric acid iron content: 15 PPMMaximum Fluorine content: 0.8 PPMMaximum Electric conductivity: 118 μMHO/INCH4) Maximum sand content: 50 PPM5) Proper approved three-phase overload protection. See TABLE B.6) Proper fusing for motor circuit protection. See TABLE C.7) Proper line voltage variation during running conditions:60Hz: 460V, 230V ±10% , 50Hz: 380V ±10%at motor lead 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)Current unbalance between legs should not exceed 5% of theaverage.8) Proper sizing of motor HP. (current, thrust, voltage, etc.)9) Motor must be set with minimum 10 feet clearance from thebottom of the well.H I TACH I SUBMERS I BLE MOTORSF1Date: 03/22/16Supersedes: 09/01/0710) In the case of horizontal installation, the motor is to be rigidlyaligned with the pump and firmly mounted to prevent any load on the shaft and bearings and to avoid any damaging vibrations to the motor.11) The motor must always be immersed in water so that a flowvelocity of cooling water at a rate of 0.5 feet per second flows past any and all parts of the motor. The motor will not operate in mud or sand.12) Hitachi motor leads are sized for operation while submergedin water at the maximum rated ambient water temperature.The factory motor leads must be fully submerged at all times during operation to avoid damage or failure.13) The power cables shall be sized large enough so that at ratedcurrent there will be less than a 5% voltage drop. See TABLEC. Cables must be waterproof submersible type.14) For three-phase motors a balanced and properly sizedtransformer bank shall be provided. Improper electrical supply (for example, phase converter, V-connection transformer, etc.) or connections will void the warranty.15) Single-phase protection is recommended for protection of theinstallation. Any failure due to single phasing of the incoming voltage causing the motor to fail will void the warranty.16) Surge suppressors are recommended in the interest ofprotecting the control panel, as well as the insulation system of the motor. Any motor failure due to lightning or other natural disasters will void the warranty.17) Provide waterproof insulation splices between all lead wiresand well cables.18) In the event that a reduced voltage starter is used to start themotor, the following should be verified:A. Correct quick trip, class 10 or better, ambient compensatedoverloads are incorporated.B. Proper short circuit protection is utilized.C. The torque required by the motor and pump package isattainable by this type starter.D. The lead arrangement of the motor is acceptable with theproposed starter load connections.E. Verify that if any time delay relays are used in switchingcontactors in and out, that the time settings do not exceed 2 seconds; this could damage the motor.F. If a manual auto-transformer starter is used, voltage shouldbe minimum 60% of rated voltage, and switched to "Run"condition within 2 seconds. Double check TABLE B and C for correct protection.19) Single-Phase Motors (5-15HP)Proper connections and correct capacitors and relays are necessary for single-phase motor starting and running.Connection diagram: See Fig. 1.Performance and recommendable capacitors: See TABLE D.20) VFD (Inverter)Please contact Hitachi for VFD(inverter) usage on Hitachi Submersible MotorsMAINTENANCEThere are no bearings that need oil or grease. The motor, being inaccessible, should be monitored through its electrical connections.1) Measure and record operating current and voltage.2) Measure and record the motor insulation resistance. Anyresistance of less than 50 megohm for a new motor should be evaluated or checked further by a qualified service shop.3) Lightning arrestors and/or surge capacitors will help preventdamage to the control box, cables, and motor.4) Single-phase protection will help in preventing motor failuredue to adverse incoming primary power.5) Based on the values obtained in A and B above and the outputflow rates and pressures of the pump, a complete picture of total performance can be obtained. This can be used to determine any pump and motor maintenance and overhauling which might be required.6) If the motor is to be stored, protect the unit from freezing bystoring in an area with a temperature higher that -30°C(-22° F). OPERATION1) After energizing the motor, check the flow and pressure of thepump to make sure that the motor is rotating in the correct direction. To correct a wrong rotation, switch any two of the three cable connections. (Three-phase motor only)2) When starting the pump for the first time, inspect the waterfor sand. If sand appears, then continue to pump till the water clears up; otherwise, sand will accumulate in the pump stages and will bind or freeze the moving parts if water is allowed to flow back down the well.3) During testing or checking rotation (such as "bumping" or "inching")the number of "starts" should be limited to 3, followed by a full15 minutes cooling-off period before any additional "starts" areattempted. Depending on the depth of the well and/or method of checking, these rotational checks or "starts" may actually be full-fledged starts. If this is the case, then a full cooling-off period of 15minutes is required between this type of start.4) For automatic (pilot device) operation, the motor should beallowed to cool for 15 minutes between starts.5) Input voltage, current and insulation resistance values shouldbe recorded throughout the life of the installation and should be used as a from of preventive maintenance.TABLE A.
