3. Couple the syringe to the inlet of the cooling circuit and press the cooling liquid inside the circuit until the manometer indicates 1
bar pressure. Ensure that no air bubbles are injected into the circuit.
Caution: Maximum 1 bar of pressure is allowed on the liquid cooling circuit. More pressure than 1 bar may damage the circuit.

4. Pressure to 1 bar by pushing in the piston of the syringe and then immediately disconnected the syringe. When this is done
properly, the manometer should indicate 1 bar.
5. Check if the cooling circuit was correctly calibrated. Proceed as follows:
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. As a result the pressure of the cooling circuit will drop from 1 to 0 bar and cooling liquid is automatically
expelled from the circuit into the syringe.
d) Check if the amount of expelled liquid is between 50 and 70 ml. If not, start the procedure "Calibrating the liquid cooling
circuit", page 175.
e) Push the plunger of the syringe to reinject the expelled liquid back into the circuit. The pressure would hence return to 1 bar.
6. Disconnect the syringe from the cooling circuit. Make sure that the pressure remains 1 bar.
7. Close up the liquid cooling circuit which you interrupted in step 1.
