16. FLM liquid cooling circuit
16.7 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 meter of plastic tube with male valved fitting.
• Half a meter of plastic tube with female valved fitting.
• Syringe equipped with male valved fitting.
• Female/female tube adapter (short tube with female valved 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 the heat exchanger.
Tip: Sometimes a little cooling liquid will be spilled. Wrap a small cloth around the valved fitting while uncoupling to absorb
the spilled cooling liquid.

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