STEP 3: A separate 8 AWG ground (green wire) conductor for the incoming circuit is required. Route the ground
wire along the same path as Line 1 and Line 2. Using a Philips head screwdriver, tighten the ground wire to the
ground lead.
STEP 4: Use a flat head screwdriver to DOUBLE CHECK the electrical connections to make sure they are correct
and that all wire connections are tight and secure. Pull on wires to ensure that they do not pull out of their
connections. Also confirm that the correct breaker size and wire gauge has been used and confirm that the unit
has been connected to a ground in accordance with applicable codes.
STEP 5: Be sure to install the front cover back on the unit before turning on power to the unit. Confirm that all
the air has been purged from the water lines prior to turning on power to the unit. Refer to STEP 3 in the
plumbing installation section.
DANGER Failure to do so can result in property damage, injury or death.
CAUTION Ensure that you have made the correct connections. You must follow the wire connection as
shown to ensure proper operation of the unit. If you mix up one set of wires with another, the unit will not
operate correctly even though it turns on and otherwise appears to function properly.
The water heater is now installed and ready to use! Follow the General Operating Instructions to complete the
setup.
