NOTES

◦Do not run signal cables along with other power or motor cables.

◦The inside diameter of process piping and fittings must be greater than the diameter of the flow path nozzle.

◦Install this product in a location where it will not be affected by magnetic fields.

◦When using the product, ensure that the main body is filled with water and that there is no air near the Impeller.

◦Do not use air blowers to blow the product. Otherwise, the Impeller and/or shaft may be damaged.

◦It is recommended that a straight section with a diameter of 10 D or larger (D: Inside diameter of the connected pipe) be provided in the

upstream piping if an uneven or swirling flow is expected to occur.
