DHC 3-1, 3-2, 4-2 Classic ship with a 0.5 GPM pressure compensating flow-reducer/aerator that must be installed.
1
Overcurrent protection sized at 100% of load (DP for 240/208/277 V & SP for 120 V models). Tankless water heaters are considered a non-continuous load.
GFCI Class A circuit breakers are recommended.
2
Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
3
Suitable for supply with cold water only.
These are our recommendations. Check local codes for compliance if necessary.
