Follow the numbered steps below for a correct installation:
1. Check that the voltage is appropriate for this appliance; you can verify this information on the
product data label (placed on one side of the heater).
2. Install the water heater as close as possible to the electric current (charging center), with the
voltage that will be used, which must be accessible and must include a switch break or QO
Breaker.
3. As a safety measure it is obligatory to install a 20 Amp thermo-magnetic circuit breaker
independently of the main line, for automatic deactivation in the case of an electrical fault or
imbalance.
4. Extend or lead the independent cables from the power supply through a conduit tube or
polyduct to the heater.
5. Use No. 12 caliber THW cable for the connections, which must be made with a interlace cable
tie. We recommend using the colors used in the water heater wiring.
6. Ensure and verify that the green physical ground wire is correctly connected to the terminal at
the charging center.
7. Insulate or tape the moorings with non-inflammable plastic insulating tape.
8. Fill the heater with water to allow the air to exit. Open a hot water service, until water comes
out the service line.
9. Once the above has been completed, you can power the heater to start its operation. Never
omit the electric circuit's ground connection (see Fig. 5). We recommend connecting the
green ground wire to a copper rod (Copperweld).
10. Grounding is obligatory for this device, and the cable (which should be a yellow-green color)
must be attached to the ground connection.
