15. Liquid cooling circuit
15.3 Refreshing the liquid cooling circuit
Over time the cooling liquid may show deterioration and hence less effective cooling characteristics. To main-
tain sound cooling properties, we advise ANNUAL replacement of the cooling liquid.
Necessary tools
• Half a m eter of plastic tube with male v alved fitting.
• Half a meter of plas tic tube with female valved fitting.
• Syringe equipped with male valved fitting.
• Female/female tube adapter (short tube with female v alved fittings at both sides).
• Bottle with 1 liter cooling liquid.
• Empty bottle with a volume of one liter.
•Cloths.
How to refresh the liquid cooling circuit ?
1. Interrupt the liquid cooling circuit by uncoupling the valved fitting at t he heat exchanger.

2. Insert the tube end of the plastic tube, which contains a female valved fitting, into an em pty bo ttle and then couple the female
valved fitting with the exit side of the cooling circuit.
Note: Circuit is p ressurized, so first insert tube end into empty bottle.
