ELECTRICAL INSTALLATION INSTRUCTIONS
Installing Wire From Electrical Panel
STEP 1
Check the wire gauge is appropriate for the intended voltage and amperage. The power supply
wire must be connected to its own individual breaker.

STEP 2
Connect the supply wire to a breaker (see wiring diagram). Make sure the breaker is connected
with one black wire and one red wire.
NOTE: ONLY supply power from a grounded system. A green terminal (or a wire connector marked
“G”, “GR”, “GROUND”, or “GROUNDING”) is provided.
To reduce the risk of electric shock, connect this terminal or connector to the grounding terminal of
the electric service or supply panel with a continuous copper wire in accordance with the electrical
installation code.
STEP 3
Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers
used, run the supply wire from the home’s main breaker panel to the MODEL 3.
NEVER wire a single MODEL 3 to multiple breakers.
NOTE: Heatworks recommends using crimps on electrical leads when connecting electrical supply
to MODEL 3.
ALWAYS complete the plumbing installation and test to check there are no leaks and all
fittings are properly installed BEFORE starting electrical installation.
