    3. Transportation, conveyance, storage and installation Precautions for transportation, moving and storing the pump (1) Do not unpack the container unnecessarily. If you unpack the container unnecessarily, securely pack again in such a manner that the product body does not jump out of it and fall down during transportation, conveyance or storage. (2) When you transport, move, or store the pump, ensure that the pump is located in a well-ventilated place with minimum exposure to dust and moisture in an environment at an ambient temperature of -25 to 55 degrees Celsius and humidity of lower than 85%RH.

  • Page 29: Precautions For Installation

    Caution Do not run a pump designed for 50Hz power supply at 60Hz. Otherwise, it may lead to overload and motor burnout. Running a 60Hz pump at 50Hz reduces its performance. Precautions for installation Warning Before turning the pump shaft by hand to check its rotation, be sure to turn off the main power.
  • Page 30 Note Always keep the liquid level in the tank (oil tank) above the Minimum liquid level. Keep the suction port of the pump at least t mm away from the bottom of the tank (oil tank). (9) The product is coated. If you need to overcoat it in a different color for a compelling reason, lightly roughen the product surface with sand paper or the like and then coat it, which improves the adhesion properties of the coating film.

  • Page 31: Precautions For Piping Work

    (15) If the pumping liquid is cold, condensation may occur inside the motor while the pump is stopped. Take measures to prevent condensation, for example, by installing the pump in a sufficiently dry room or by heating and insulating the motor even when the pump is stopped. (16) Carry out touchup painting at a time interval suitable for the environment of use.

  • Page 32: Precautions For Wiring Work

    Refer to the “Starting electric current” and “Rated electric current” specified in “2.5. Specification table [page 2-4].” If you have any questions, contact Teral. Note When you switch from an IE1 motor-equipped product, it is necessary to verify the applicability of its protection device on the primary side of the pump.

  • Page 34 (6) Take adequate dust-proofing and drip-proofing measures using a connector, gland, or other means to prevent any cutting powder and liquid coolant from entering the terminal box through the external wiring hole. (7) Pass the power cable through a metal tube or a metal conduit for shielding, and connect a ground wire to the outer surface of the tube.

    4. Operation Check items before test operation 4.1.1 Check items related to the electrical system (1) Check that the equipment is correctly wired. (2) Check that the terminals are securely connected. (3) Check that the equipment is securely grounded. (4) Check that the setup value of the overload protection device is consistent with the rated current value of the motor.

  • Page 36: Running The Pump (Test Operation)

    (5) If you run the motor at variable speed with the inverter, be sure to check the following points through test operations. • The pump may produce resonance depending on installation conditions. If the pump produces resonance, avoid that frequency. •...
  • Page 37 Caution Never check the rotation direction by running the pump dry even for a short time. Otherwise, it may damage the sliding parts (e.g. casing, bearings) in the pump, or lead to leakage or unusual noise. Caution Do not run the motor in reverse because it may cause a failure. Caution Do not run the pump dry, and do not allow a large amount of air or foreign matter from entering the pump.
  • Page 38 (8) Limit the frequency of the startups and shutdowns according to the following table: Allowable frequency of startups Model (times/hour) LVS (4.0 kW or less) LVS（5.5 to 18.5 kW） Caution Minimize the frequency of startups and shutdowns of the pump because their high frequency may quickly damage the pump.
  • Page 39 (14) Stop the pump. Caution Keep the cocks of the pressure gauges, compound pressure gauges, and other parts closed all the time except when they are used for measurement. Otherwise, they are more prone to fail. Caution Do not run the pump using the power beyond the allowable current value. Otherwise, the motor may burn out.

  • Page 40: Maintenance And Inspection

    Caution For overhaul, replacement of parts, or repairs, ask the vendor or the service center specified by Teral. Incorrect work may cause a failure or accident. Precautions for maintenance and inspection (1) Observe the following points, in particular, during daily inspection.

  • Page 41: Tightening The Coupling

    (2) f you do not use the pump for a long time, observe the following points: Caution If you do not use the pump for a long time, turn off the power for safety. Otherwise, accumulated dust may cause heating or ignition. ...

    (affixed to the motor). For the bearing type, refer to the following table. * If you use any motors other than the standard, check the maintenance plate affixed to the motor or contact Teral. [Grease refilling procedure] • Refer to the grease name plate on the motor for the grease refilling intervals and amount.

  • Page 43: Periodic Inspection

    Periodic inspection (1) Clean any dirt, oil, and other deposits off the outer surface of the coolant pump. (2) Cutting powder deposited in the tank (oil tank) may cause a pump failure. Periodically clean the tank (oil tank). (3) Check the strainer of the pump for any clogging. Clean it if it is clogged. Caution Periodically clean the strainer located on the pump suction side.

  • Page 44: Troubleshooting

    6. Troubleshooting The following table lists causes of failures and their actions. In the event of a failure, however, you should carefully investigate the problem and ask the vendor to carry out any actions that are not easy to take. Problem Cause (Reference page) Action (Reference page)

  • Page 46: After-Sales Service

    If you find anything unusual about the active pump, immediately stop the pump and then check the problem. (Refer to Section “6. Troubleshooting” [page 6-1].) For disassembly, inspection, or repair, ask the vendor from which you purchased the product or ask Teral. (Refer to the end of this document.) ...

  • Page 47: Disposal

    8. Disposal Precautions for disposal Before detaching the pump from the system for disposal or replacement, be sure to turn off the main power. Warning Before detaching the pump, be sure to turn off the main power. Otherwise, the pump may suddenly start up in automatic mode or on other occasions, thus leading to great danger.
