DHC 3-1, 3-2, 4-2 ship with a 0.5 gpm (1.9 l/min) pressure compensating flow reducer/aerator that must be installed.
1
This is our recommendation for overcurrent protection sized at 100% of load. (
necessary. Tankless water heater are considered a non-continuous load.
2
Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load
