Visual Inspection
Confirm 30-mA ground-fault device (proper rating/function)
Confirm all electrical connections in the RayClic and HWAT-ECO are tight
and wires secure.
Visual inspection inside connection boxes for overheating, corrosion,
moisture, loose connections and other problems.
Proper electrical connection, ground, and bus wires insulated over
full length.
Correct thermal insulation used for each pipe size (Reference Table 2)
Damaged or missing thermal insulation for the entire hot water piping system.
Covered end seals, splices, and tees properly labeled on insulation.
Check HWAT-ECO for moisture, corrosion, setpoint, switch operation
