Replacing Aquapure 1400 Sensor

[engteach43]

The sensor on my AquaPure 1400 needs replacing. Two different pool repair companies want close to $400 to replace it. It looks very straight forward as far as unplugging the old sensor from the circuit board and plugging the new one in. This is the newer version of the system with the rounded cell instead of the old square edged one. If I do it myslef, is there anything else I need to do other than unplugging the old sensor and plugging in the new one to replace it? Obviously, I'll make sure the power is off to the system before changing it, but are there any other steps required? I can't find anything specific in any of the manuels for the system or on any of the forum entries. Any advice would be great.
