* AQM 2-1 is internally restricted to 0.32 gpm (1.2 l/min).
1 Nominal mains voltage is 110–120 V and 220–240 V.
2 This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.
Tankless water heater are considered a non-continuous load.
3 Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.
4 For use with cold water supply only.
