16. FLM liquid cooling circuit
16.9 Pressurizing the liquid cooling circuit
Before pressurizing the liquid cooling circuit ensure that the circuit is filled with cooling liquid and that all air
bubbles are expelled.
C
AUTION
:
This procedure is only valid in case the liquid cooling circuit is calibrated. This means that the
pressure vessel was not subject to any modifications, i.e. releasing or increasing pressure via the valve of the
vessel. In case the pressure vessel was subject to modifications use the calibration procedure to pressurize
the liquid cooling circuit.
W
ARNING
:
All actions performed on the liquid cooling circuit should occur in ambient conditions (25°). The
projector should have sufficiently cooled down (minimum 2 hours).
Necessary tools
•
Half a meter of plastic tube with female valved fitting.
•
Syringe connected with short tube with male valved fitting.
•
Bottle with cooling liquid.
•
Cloths.
How to pressurize the liquid cooling circuit ?
1. Interrupt the liquid cooling circuit by uncoupling the valved fitting at the heat exchanger if not yet done.
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. Fill the syringe with cooling liquid as follows:
a) Couple the female (F) fitting of a plastic tube to male (M) fitting of the syringe and emerge the tube end. Make sure that the
piston of the syringe is completely pressed in.
b) Extract cooling liquid into the syringe by pulling out the piston.
c) Turn the syringe upside down, so that the air inside the syringe is located at the outlet.
d) Push the piston in until all air bubbles inside the syringe and tubes are expelled. Ensure that the tube end in the bottle remains
emerged.
e) Pull out the piston to fill the tubes and syringe completely with cooling liquid. Keep holding the syringe upside down.
f) Disconnect the filled syringe from the tube. Make sure that there is no air inside the tube or syringe. If necessary push the
air outside the syringe and tube before disconnecting.
