16. FLM liquid cooling circuit
a) Couple the female (F) fitting of a plastic tube to male (M) fitting of the syringe and emerge the tube end. Make sure that the
piston of the syringe is completely pressed in.
b) Extract cooling liquid into the syringe by pulling out the piston.
c) Turn the syringe upside down, so that the air inside the syringe is located at the outlet.
d) Push the piston in until all air bubbles inside the syringe and tubes are expelled. Ensure that the tube end in the bottle remains
emerged.
e) Pull out the piston to fill the tubes and syringe completely with cooling liquid. Keep holding the syringe upside down.
f) Disconnect the filled syringe from the tube. Make sure that there is no air inside the tube or syringe. If necessary push the
air outside the syringe and tube before disconnecting.

4. Fill the pressure vessel with liquid as follows:
a) Couple the syringe with the inlet of the cooling circuit. Keep holding the syringe vertical with the outlet downwards.
b) Increase the pressure by pushing in the piston of the syringe (maximum 1 bar indicated on the manometer).
c) While pressing, expel air from the pressure vessel.
d) Continue expelling air while pressurizing the circuit (up to 1 bar) until the valve of the vessel becomes hard to push in. This
indicates that the pressure vessel is completely filled with cooling liquid.

5. Now that the pressure vessel is liquid filled you have to increase the pressure to 1 bar by pushing in the piston of the syringe.
Then immediately disconnected the syringe. When this is done properly, the manometer should indicate 1 bar.
6. Extract 75 ml back into the syringe by doing the following:
