2. Servicing the liquid cooling circuit
2.4 Refreshing the liquid cooling circuit
Over time thecoolingliquid may show deterioration and hence less effective coolingcharacteristics. To main-
tain sound cooling properties, we advise ANNUAL replacement of the cooling liquid.
Necessary tools
2 x 60 cm of plastic tube with male valved fitting.
Syringe equipped with male valved fitting.
Female/female tube adapter (short tube w ith female valved fitting 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. Close the vane.
2. Insert the tube end of the plastic tube, which contains a male v alved fitting, into a bottle filled w ith a little cooling liquid and then
couple the male valved fitting with the outlet of the cooling circuit.
Note: Circuit is pressurized, so first insert tube end into empty bottle.
3. Fill a plastic tube, which contains a male fitting, with cooling liquid as follows:
a) Connect a tube, which contains a male (M) fitting, to the male (M ) fitting of the syringe using a female/female (F) adapt er.
b) Emerge the tube end and make sure that the piston of the syringe is completely pressed in.
c) Extract cooling liquid into the syringe by pulling out the piston.
d) Disconnect the filled tube from the syringe. Make sure that the tube remains immersed.

Caution: It’s important that there is no air inside the tube. T
he pump is not self priming and hence is only capable of sucking
through small volumes of air.
4. Push the male valved fitting of the filled tube into the inlet of the cooling circuit. M ake sure that the inlet of the filled tube remains
immersed.
