STEP 1: Take the wire pair and connect to the breaker. Be sure that the breaker is connected
to one black wire and one red wire. Be sure the power to the unit is shut off using the dedicated
circuit breakers in the main electrical panel.
STEP 2: Run the correct set of power cable wires from the circuit breaker in the main electrical
panel to the water heater by utilizing a suitable wire gauge which meets all applicable electrical
codes for the size of the breaker. Then, connect the power cable to the block terminal within the
water heater.
STEP 3: Each incoming circuit requires a separate ground conductor.
STEP 4:
DOUBLE CHECK The electrical connections and ensure the wire connections are
correct, tight and secure. It's important to confirm that the right breaker size and wire gauge has
been used and that the unit has been connected to a ground in accordance with applicable codes.
Be sure to reattach the front cover of the unit with four screws.
STEP 5: Ensure that all the air has been purged from the water lines before turning on power to
the unit. Refer to STEP 3 in plumbing installation section. Restore power to the unit through the
dedicated circuit breaker in the main electrical panel.
It is crucial to follow the wire connection as shown and ensure all connections are made
correctly for proper operation of the unit. The unit will not operate correctly if you mix up the
wire sets, even though it turns on and otherwise appears to function .
