Go for it soon or you will regret it.
The first time is a bit daunting but it gets easier...soon you'll be an old pro and trundle the cassette without a problem.
Can suggest when you do the first evacuation and rinse it out then put a bit of water back not the cassette and, when reinserted, add the chemical straight away. Then you won't have to worry till next time.
