High voltage is accessible in several locations within this instrument.
Make sure you unplug the power source before removing the cover or
performing maintenance procedures.
There are four filters in the Model 3090 that may require changing at some
time during the operational life of your Model 3090. To replace the filters,
proceed as follows:
1. Obtain TSI Manifold filters: PN 1602051; TSI Pump filters: P/N 1602230.
2. Switch the instrument off and unplug the power cord.
3. Loosen the screws of the top panel and lift it off (Figure 6-1).
4. Face the left side of the instrument. Loosen the two screws on the side
of the left panel and then loosen the two screws on the back of the left
panel.

Manifold Filters
To change the large Manifold filters proceed as follows:
1. Locate the manifold filters, refer to Figure 6-23.
2. Remove the thumbscrew from the top of the filter block.
3. Lift the filter block up.
4. If necessary, separate the tubing at the block fitting by pushing the
fitting retaining collar IN while pulling the tube out of the fitting. The
collar is located where the tube is inserted.
5. Install the new manifold filters making certain they are oriented with the
flow arrows pointing DOWN.
6. Push the filter block back down over the filters and tighten the thumbnut.
7. If tubing has been removed, push the tubing back into the fittings,
inserting fully so that the tubing is coming straight out of the fitting. If it
comes out at a sharp angle, the fitting will not seal properly against the
tubing.
