Our 8900 unit came in late 2018. It has been suggested that we should change the coolant in the chiller. As far as we can tell we have no instructions how to do so. We can see the drain on the back. is it as simple as
- turning off the chiller,
- unplugging the power
- putting something under the drain.
- opening the drain and collecting all the coolant in a suitable container
- closing the drain.
- opening the cap on the top and putting in fresh coolant until the max level is reached
I did see reference to to having to clean a sieve that in the coolant reservoir and also having to add a bit more coolant as the level will drop once it is turned back on but it wasn’t clear
