SafetyEasy installation

Fluid flow from low flow rate (0.55
GPM) can be visually checked withthe rotating two-colored impeller.

Flow Vane ASSY can be replaced
without removing it from the piping(both models).

The stopper prevents unintended
removal of the plastic parts.

The installation and replacement iseasy since the screw part of T2 siderotates freely to the left and right.

Recommended
replacement timeof Flow Vane ASSY

The recommended replacement time for this product is calculated basedon the amount of wear on the internal parts of the Flow Vane ASSY.
Refer to the graph below for the recommended replacement time.
*The durability varies depending on the usage environment andconditions. (pressure, temperature, etc.)30

If the Flow Vane ASSY is dirty
or cloudy and the impeller isdifficult to see, replace it
regardless of the recommended
replacement time.
