    Precautions During Installation Hose clamp Hose (1) Push the hose all the way to the base of the hose Discharge connection coupling. Tighten the hose clamp to secure the hose in Hose coupling place. Note: A hose coupling designed for use with a suction hose is available separately.
  • Page 10 (4) When using a hose to provide piping to the pump, observe the following: Use the shortest possible length of discharge hose and minimize the number of bends. Verify that the end of the hose (discharge side) is lifted above the water surface. If the end of the hose is submerged in water, it may cause the water to flow back when the pump has been stopped.

    5 ELECTRICAL WIRING Electrical Wiring Work WARNING • All electrical work must be performed by an authorized electrician, in compliance with local electrical equipment standards and internal wiring codes. Never allow an unauthorized person to perform electrical work because it is not only against the law, but it can also be extremely dangerous.
  • Page 12: Operation

    KTZ models (models with 22kW power output) Ground Miniature Protector 6 OPERATION Before Operation CAUTION Improper voltage and frequency of the power supply will prevent the pump from attaining its full potential, and may also lead to current leakage, electrical shock, or fire. (1) Once again, check the nameplate of the pump to verify that its voltage and frequency are correct.
  • Page 13 Direct-on-line starting To reverse the rotation, the following countermeasure must be taken. COUNTERMEASURE Interchange two of the three wires designated U, V, and W, respectively. Ground (Example) Interchanging phases V and W (2) Operate the pump for a short time (3 to 10 minutes) and perform the following checks: Operating current Using an AC ammeter (clamp), measure the current at the phases U, V, and W that are connected to the terminal board.
  • Page 14: Motor Protection System

    Motor protection system WARNING • During inspection and repair, disconnect the power supply to avoid starting the pump unintentionally. Failure to disconnect the power supply may lead to serious accidents including electrical shock, short, and injury. • During a power outage, disconnect the power supply to the pump. Unintentional operation of the pump after power resumption would be extremely dangerous to people around the pump.
  • Page 15 In the Case of Automatic Pumps Starting of a pump The pump starts when the current (micro current) continuously flows between a conductive part(Shaft, Bolt, etc.) and the electrode level sensor for more than one (1) second. Note: The electrode may not detect the water surface under conditions such as purif ed water or distillated water with which the current does not f ow because of high specif c resistance.
  • Page 16 Operating Principle of the Automatic Pumps This explains the control form by a combination of an electrode and a timer function. Please understand the performance of this pump and apply it. Water Electrode Level Sensor Pump Condition Level Electrode level sensor will submerge and the [Switch on] pump will operate by the current.
  • Page 17: Maintenance And Inspection

    7 MAINTENANCE AND INSPECTION Periodic maintenance and inspection are indispensable in maintaining the pump's performance. If the pump behaves differently from its normal operating condition, refer to the section "9. Troubleshooting" on page 23 of this manual and take appropriate measures at an early stage. It is recommended that a spare pump be prepared on hand.
  • Page 18: Replacement Parts

    Storage If the pump will not be operated for a long period of time, pull the pump up, allow it to dry, and store it indoors. Note: Be sure to perform a trial operation before reinstalling the pump. If the pump remains immersed in water, operate the pump on a regular basis (i.e. once a week) to prevent the impeller from seizing due to rust.
  • Page 19: Disassembly And Reassembly Procedure

    8 DISASSEMBLY AND REASSEMBLY PROCEDURE Prior to Disassembling and Reassembling WARNING Before disassembling and reassembling the pump, be sure that the power supply (i.e. circuit breaker) is disconnected, and remove the cabtyre cable from the terminal board. To prevent serious accidents, do not perform a conducting test during disassembly and reassembly.
