(-15%, +10%).
AC
Reduce the hot water consumption. Wait un-
til the water heater heats up.
•
Make sure that the voltage between
the connections of the heating ele-
ments is 230VAC (-15%, +10%).
•
Refer to indication "A safety device is
activated", next page.
•
Make sure that the water heater is fil-
led with water.
•
Measure the resistance value between
each heating element connection and
the outside of the tank. The value
must be infinite.
•
Determine which element is defective.
•
Make sure the water heater is com-
pletely filled.
•
Tap off water, so the temperature
drops in the water heater.
•
Make sure all connections are connec-
