pump, letting the fluid in the tubing drain out the instrument outlet. Leave
the tubing connected to the outlet Y-fitting.
9. Repeat this process to disconnect the outlet tubing from the other
membrane module, removing the tubing from the interior of the analyzer
and letting the fluid in the tubing drain out the instrument outlet.
10. Disconnect the pump tubing from 1/16" stainless steel tubing attached to
the bulkhead fitting and dispose of the old tubing.
12. Use a paper towel to cleanup any liquid that may have spilled inside the
instrument.
To install the new tubing:
1. Remove the tubing from the shipping container. The tubing for the
TC channel is the longer piece.
2. Connect the single end of the new tubing to the 1/16" stainless steel
tubing attached to the bulkhead fitting.
3. Feed the tubing around the sample pump and behind the syringe
pumps to the membrane modules.
IMPORTANT!
It is crucial that steps 4 and 5 are followed exactly. The shorter piece of tubing
must be used on the IC membrane module and the longer piece of tubing must
be used on the TC membrane module. Failure to do so will result in
interference with the movement of the syringe pump armature.
4. Connect the SHORTER piece of tubing to the IC membrane modules
(the one closest to the back of the analyzer).
5. Connect the LONGER piece of tubing to the TC membrane modules
(the one closest to the front of the analyzer).
6. Position the tubing one on top of the other in the slots of the support
bracket with the plastic collar just to the left of the bracket. Replace
the top piece of the bracket, and secure with the wing nut. Do not
pinch the tubing with the support bracket.
