12. Slide the wick back onto the saturator base using the two dowel pins to
key it. This will keep the holes aligned as the wick is replaced in the
CPC. Replace the 2-inch screw and washer.
13. Keep the CPC turned off and the vacuum supply disconnected from
the external vacuum port on the back panel. Tilt the CPC on its side to
access the bottom panel. The CPC can lie flat on its side but do not
turn it upside down.
14. Reinsert the wick and base and secure to CPC using the three screws
indicated in Figure 8-5. In case the wick does not insert easily, follow
these tips:
i. If the CPC has recently been turned off, the saturator may still be
warm. Let the saturator cool down to room temperature before
inserting the wick.
ii. Apply Krytox O-ring grease (accessory kit) to the bottom O-ring
only. Do not use silicon-based O-ring grease.
15. Reinsert the inlet tube and secure the sleeve with the screw indicated
in Figure 8-4.
