Technical Data
Specifications
* Minimum flow may vary slightly depending on the temperature setting and the inlet water temperature.
Minimum activation flow is 0.4 GPM (1.5 L/min).
Our products are continually being updated and improved; therefore, specifications are subject to change without prior notice.
The maximum inlet gas pressure must not exceed the value specified by the manufacturer. The minimum value listed is for the purpose
of input adjustment.
