13. Disconnect the drive and flip the chamber.
14. Turn off the nitrogen supply valve.
15. Slowly open the nitrogen vent valve until the gauge reads 300 psi.
16. Turn the regulator handle out until gauge needle just moves and venting is
barely heard and reads 200-250 psi on the gauge.
7.5 Filtrate Condenser
1. Set the chamber pressure regulator to 200 psi.
2. Rotate the coolant valve to direct air into the heating jacket cooling lines to
expel water. Close the valve when only air is heard escaping from the drain
line.
3. Close the coolant valve by rotating the handle up.
4. Disconnect the cooling lines from the heating jacket.
5. Connect the filtrate unit to the sample chamber. Hand-tighten only.
6. Connect the cooling lines to the filtrate unit.
7. Slowly open the coolant valve by turning the handle to the right.
8. Check all fittings for leaks for at least 5 minutes.
9. Slowly rotate the cooling valve to the left. This directs air into the cooling lines
to expel water. Close the coolant
valve (handle up) when only air (nitrogen) is
heard escaping from the drain.
10. Turn the nitrogen and coolant valves off. Release the pressure setting on the
regulator by opening the filtrate condenser chamber with 500 mL cup under
port and allow the 400-500 mL of water to expel and then open the nitrogen
vent valve to bleed off nitrogen as the regulator is turned down.
Bleed off pressure before tightening fittings by turning off the bottle
and opening the nitrogen vent valve.
