Technical Data

Specicaons

* Minimum ow may vary slightly depending on the temperature seng and the inlet water temperature.

Minimum acvaon ow is 0.4 GPM (1.5 L/min).

Our products are connually being updated and improved; therefore, specicaons are subject to change without prior noce.

The maximum inlet gas pressure must not exceed the value specied by the manufacturer. The minimum value listed is for the

purpose of input adjustment.
