When distilling, small amounts of the extract can find their way into the condenser and pump assembly.
This will lead to lower pump performance, and ultimately prevent Merlin400 from gaining the necessary vacuum.
This is a cause of many error messages, but luckily it is rather easy to wash the condenser and pump array.
The following procedure ‘washes’ the pump and condenser with IPA fumes from the distillation chamber. Here is how:
1. Insert the clean, empty herb tube in the extraction chamber (left, hemp leaf imprint).
2. Mount a clean, empty collection glass with glass beads. Tighten the elevator ring.
3. Open the top lid of the distillation chamber, and add approx. 30 ml IPA to the collection glass, so that the glass is about half full.
4. Open the IPA chamber (right, drop imprint) and check if there is free space for the extra IPA.
5. Run program 4: ‘Just Distil’
6. If the machine is very dirty and has problems gaining enough vacuum, it will stop after a few minutes.
If the machine stops with an error message, just reset it by pressing and holding the select and pause buttons, then start prg 4 again.
You can repeat this until you see the IPA starts boiling in the oil glass.
6. When the IPA has evaporated and the glass is empty, you can reset the machine.
There is no need to let it perform the whole end sequence.
