1
This is our recommendation for overcurrent protection sized at 100% of load (
DP
for 2
40/208/277 V & SP
for
120 V
models).
Check local codes for compliance if necessary. Tankless water heaters 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.
3
Suitable for supply with cold water only.
Tested and certified by WQA
against NSF/ANSI 372 for lead
free compliance.
Certified to ANSI/UL Std. 499
Conforms to CAN/CSA E335-1 & E335-2-35
