The antifreeze liquid mixed water inside the piping can also be discharged

heater device has been cooled down completely.

device.
Make replacement turning the
power OFF, and after removing
the blue colored socket.

As there is no need for the time for cooling down of the hot water, the replacement
works can be performed within a short time, but the antifreeze liquid mixed water
inside the piping cannot be replaced.
Further, when the power has been put on this device for a while, the temperature of
the water heater tank does not go down soon even if the power is turned OFF.
When the water heater tank is at an elevated temperature, there exists possibility of
burn injury.
