The pump should always be installed with the shaft, oriented horizontally, the motor terminal box should not be in the bottom position. The pump motor should not be isolated (requires contact with atmospheric air to cool the windings), and it is important that the drainage hole in the flange of the pump was clogged. The direction of flow through the pump housing indicated by the arrow. If the pump is mounted in a vertical pipe, the flow must be directed upwards. If a stream goes down, then release the air valve should be mounted at the highest point on the suction line of the pump.
3-phase pump Taco Electrical connection:
Pumps shall be connected in accordance with existing regulations. If you use a regular starter, overload protection must be installed in accordance with rated current (NT), as indicated on the label (Note: NT varies with selectable speed).
Thermal overload protection built into the windings of the majority of electric motors. When the connection is made through contactor TACO 007 (see instrument control of this guide) overload protection automatically set regardless of the selected rate. For detail of the existing schemes of electric connections, please refer to page 15.
Release the air and the direction of rotation of the rotor:
Before starting the pump to remove air through vyvertyvaniya tube, located in the center of the badge on the motor housing. When the tube is removed, should be checked direction of rotation of the motor. Rotation must be counterclockwise, as shown by the arrow on the label. When the dual single-hull pump mounted in a horizontal pipe, the air from the upper pump must be removed through the tube on the pump casing
Preparations for the first launch:
* The system must be thoroughly rinsed from the particles remaining after soldering or welding, steel wool, plaster and other foreign particles that may be in the pipeline
* Ensure the correct alignment of the pipeline and it is secured on both sides of the pump
* We recommend installing valves on each side of the pump
* To prevent the accumulation of suspended particles in the pump, do not install the pump at the lowest point of the system
