mode to open valves. To check flow of water through the
conductivity cells:
1. Locate the restrictor tube on the DI side of the fluidics module. It is a narrow,
looped plastic tube.
2. Disconnect the PEEK fittings on each end of the restrictor tube.
3. Flush the tube with water, then reconnect it.
4. If the restrictor tube is clear, check the flow through the T-fitting that the restrictor
tube is attached to. Disconnect the PEEK fittings from the T-fitting and verify flow
by flushing the fitting with water.
