M. Heating Element Replacement Procedure
If heating elements need replacement, it is very important to use
the same voltage, wattage, and construction. The element sheath
must be incoloy and the hex plug must be made of stainless steel.
Step #1
- Turn off power to the water heater. Use a Phillips Head
screwdriver to remove the wires from the element.
Step #6
- Reattach the access cover with the two screws.
Step #7
- Restore power by
replacing the fuse or turning
on the circuit breaker.
Step #8
-
a.
After resetting the
ECO, ensure the water
heater is operating
properly before leaving
the installation.
b.
After adjusting the
water temperature, allow
the water heater enough
time to heat the water to
temperature. After the
water heater has stopped
heating, measure the
water temperature at a
hot water outlet in the
structure.
Step #9
- If the water heater
is operating properly and
the water temperature is
satisfactory, adjustment is
complete.
