INITIAL OPERATION AND TESTING OF CONTROLS (INSTALLER ONLY)
1. Turn on power to the water heater and fully open a hot water tap.
2. Check the operation of the water heater. Check the operation of the remote temperature
control(s). Check the operation of the power failure protection system (drain solenoids).
3. Explain the proper operation of the new Bradford White EverHot
water heater to the end user.
Troubleshooting – Electrical
There are a number of (live) tests that are required when fault finding this product. Extreme care should
be used at all times to avoid contact with energized components inside the water heater. Only trained
and qualified service technicians should attempt to repair this product. Before checking for resistance
readings, disconnect the power source to the unit and isolate the item from the circuit (unplug it).
