====== How to flush the Coils======

===== Preperation =====

Before you start to the procedure you should get everything together, that is needed. 

=== You need ===
	* Vinegar essence
	* Destilled Water
	* Boxes (I recommend at least two)
	* Submersible pump
	* Power supply
	* Blind plugs 2x
	* Spanner (19, 17 & 14)
	* Some paper

===== Getting started =====
  - Turn off the pump and chiller.
  - Make some space where the bigger pipe is split for the upper and lower coils (underneath the S-MOT Laser-System).
  - Put a box there and remove the big pipes from the Tee. Do this above the box, since the water will start to drain out of the big pipes.
  - Close the big pipes using the blind plugs.
  - Connect the pump to the Input-Tee (labels are on the smaller pipes).
  - Put the pump into a box with water (you can use tap water) and vinegar essence (I used a quarter of a bootle).
  - Fix the Outut-Tee so that the water will drip into the box again.
  - Connect the pump to the Power supply (check that the voltage is reduced to zero).
  - Now slowly increase the Voltage until the water starts to drip out of the Output-Tee. Increasing the voltage too fast will cause the pump not to work.
  - If the water starts to circulate you can increase the Voltage to max 12V.
  - Flush the coils for a couple of hours
  - When you are done with flushing the coils you have to flush the coils with destilled water, to remove all residuals of the vinegar-water-mix (flush it with ~5 litres NOT CIRCULATING)
