Installation Instructions
Model #GPWC310001AC001
Feed Water Chemistry Requirements
• pH: 6.5 to 8.5
• Hardness (maximum): 75 grains (1282 ppm CaCO3)
• Water Pressure: 15 psi to 90 psi (1.03 bar to 6.2 bar)
• Temperature: 40°F to 100°F (5°C to 38°C)
• Chlorine (maximum): 2 ppm
• Iron (maximum): 0.3 mg/l
• Manganese (maximum): 0.05 mg/l
• Copper (maximum): 1.3 ppm
• Oil & H2S: Must be removed before PeakFlow A
• Polyphosphate: Must be removed before
PeakFlow A
• Silica (maximum): 20 ppm
PeakFlow A + media does not reduce silica
scaling. While silica tends to have a less
significant effect on scale formation than other
minerals, it can act as a binder that makes water
spots and scale residue outside the plumbing
system difficult to remove.

and Maintenance below).
Introduction
The PeakFlow A System prevents scale build-up on the inner
pipe surfaces of the heat exchanger inside the tankless water
heater. When installing or using the filter, or when replacing the
filter, be sure to refer to the manual.
