    3. Installation Before using the pump Upon receiving the pump, check the following points first. The container may greatly incline depending on its center of gravity. Caution Before unpacking, ensure that the delivered container is placed in the correct orientation (not upside down). Pay special attention to nails especially when opening a wooden crate.
  • Page 12 Caution Install the product so that the total suction head (suction height + suction pipe resistance) is as small as possible within the standard specifications. Also it cannot be used if the water temperature exceeds 40 , due to the °C limit for self-priming capacity.

    (6) If the system could be exposed to the freezing temperature in winter, ensure to take measures to prevent freezing in the pump room or to prevent the pump, sluice valves, piping, and other devices from freezing. (7) Use sound-insulating materials for door and walls of the pump room. Especially if there is a risk that the noise may cause problem, take necessary measures against the noise.

    (8) Be sure to align the shafts correctly. (SP(3)/SP(3)-e, MSP/MSP-e) Although the shaft is aligned at the factory before shipment, it could get misaligned during transportation or installation (at fastening the anchor bolts). Check the alignment and re-align it after the installation is complete. For the model MTP/MTP-e, the shaft of the pump is directly coupled with the motor and there is no need for alignment.
  • Page 15 (2) Be sure to provide pipe supports so that the weight of pipes is not applied directly to the pump main body. Caution Be sure to provide pipe supports for the pipes. Otherwise, the main shaft may be displaced from the center, thus leading to the equipment damage, vibration, or noise.
