Notes:
1. Flow settings for fixed versions are calibrated using water at +70°F on increasing flow, with units in a
2. Adjustable units that are set to customer specification are subject to GEMS test stand accuracy.
3. Use of 150 micron filtration is recommended.
4. Minimum 5 PSI line pressure required.
