Removin g a nd Ins t a l l i n g the S a t urator
Wick
C a u t i o n
Removing the saturator wick will cause butanol (butyl-alcohol) vapors to
diffuse into the work space. Wick replacement operations must be
performed in a well ventilated area, ideally under a fume hood. If
unfamiliar with butanol, refer to the Chemical Safety information at the
front of this manual.
C a u t i o n
Whenever the instrument is turned on, the Auto-Fill is activated. Do not
run the instrument with the saturator assembly removed to prevent spilling
butanol from the butanol reservoir.
Tools Needed
Plastic bag with seal, Phillips-head screwdriver, and paper towels. Refer to
figures that follow.
To remove and reinstall the saturator wick, follow the instructions below.
1. Find a plastic bag with seal, suitable to hold the 3” 1.75” saturator wick.
The wick will likely be wet with butanol when removed and needs to be
placed in the bag immediately to reduce release of butanol vapors.
2. Connect the Drain Bottle to the drain port at the back of the instrument.
3. Initiate the Manual Drain option as described in “Draining Butanol from
the Butanol Reservoir” section.
4. Once drained, turn the CPC off and remove the vacuum source from the
external vacuum port.
5. Remove the inlet screw indicated in Figure 8-4 on the front panel and
pull out the inlet tube. The inlet tube will not pull all the way out. It will
stop when it has cleared the saturator block, approximately half an inch.
