DHC-E 3/3.5-1 Trend ships with a 0.5 gpm (1.9 l/min) pressure compensating flow-reducer/aerator that must be installed.
DHC-E 4/6-2 Trend ships with 2 x 0.5 gpm (1.9 l/min) and a 1.0 gpm (3.8 l/min) pressure compensating flow-reducer/aerator that must be installed. See section 11.3, "Aerator
installation at connected faucet," pg. 17 for more information.

Factory default setting is jumper position 2 [high]
2
Overcurrent protection sized at 100% of load. Tankless water heaters are considered a non-continuous load. Use only GFCI Class A circuit breakers.
3
Copper conductors with a temperature rating of 75 °C or greater must be used.
These are our recommendations. Check local codes for compliance if necessary.
