Step 1: Remove cover of the water heater carefully and locate the electrical
disconnect breaker on the bottom left hand corner facing the unit.
Step 2: Use the correct wire gauge that meets all NEC or country of installation
guidelines based on the size of the breakers used to feed the unit and the
length of the wire run. Then run the set of wires from the home’s main panel
to the tankless water heater. (See above chart for minimum wire size) This
minimum wire size is based on maximum of 50’ of length.
Step 3: Take each wire pair and connect them to one breaker (see wiring
diagram). Make sure that each breaker is connected with one red wire and
one black wire.
