1. Vibration isolator shall be arranged symmetrically along the central axis of the pump unit. Vibration isolator can be a clockwise direction or an anticlockwise direction

2. When the unit Vibration isolator has six mounting points，four of them are arranged on the four corners of the inert block or the section steel frame，and the other two should be set on the long side line，and its position should be adjusted so as to keep the compression deformation of the Vibration isolator as consistent as possible.

3. When installing a damping spring isolator for horizontal water pump unit，in general，the isolator should be fixed by connecting the bus between ground, inert block or section steel frames.

4. When the vibration isolator of the vertical water pump unit is installed, the profiled steel frame should be installed under the base of the water pump unit and be installed by anchoring; the profiled steel frame and the Vibration isolator should be fixed with bolts (with spring washers). An anchor bolt is set on the ground or floor, and the Vibration isolator is fixed on the ground or floor after the anchor bolt.

5. The sideline of the Vibration isolator shall not exceed the sideline of the inert block; the supporting area of the section steel frame shall not be less than the area of the Vibration isolator.

6. Before construction and installation, it should be checked in time. During installation, the static compression deformation of the Vibration isolator shall not exceed the maximum allowable value.

7. When the water pump unit is installed, the supporting ground on which the water pump unit is installed must be flat and should have sufficient bearing capacity.

8. The Vibration isolator of the unit should avoid contact with substances such as acids, alkalis and organic solvents.
