16. FLM liquid cooling circuit
a) First empty the syringe but make sure that the tube of the syringe remains filled with cooling liquid.
b) Couple the syringe (plunger completely pressed in) with the inlet of the cooling circuit. Keep holding the syringe vertical with
the outlet downwards.
c) Release the plunger. Note that cooling liquid is pressed into syringe while the pressure drops.
d) Now fill the syringe by slowly pumping air into the vessel (connect air pump to valve).
e) Stop once 75 ml has been expelled.
f) Disconnect the syringe from the cooling circuit.

7. Close up the liquid cooling circuit which you interrupted in step 2.
8. Pump up the air pressure to 1barand reinstall the valve cap tightly of the pressure vessel.

9. Mark the pressure vessel with the calibration date for future reference.
The air hose fitting of the air pump must be of the Shrader valve type (A) to match with the pressure vessel,
so the Presta valve type (B) has to be removed. Futhermore, the pin (C) inside the Shrader valve has to be
removed as well.

Check within 24 hours whether the pres
