LS-15IIE/55IIE MODELS:
1. Open the lid and remove any residues from a previous run. Make sure that the inside of the boiling chamber is
clean and free of debris.
CAUTION:
When cleaning, use only plastic or other non-metallic utensils to avoid scratching the boiling chamber
when scraping out residues. Scratching the non-stick coating results in permanent damage and voids the
warranty.
2. Install a Stilbag or a Stilpan (if used, see Installing a Stilbag). If using a JetVac attachment, prepare the JetVac
for operation (see Start-up and Operation: JetVac).
3. Fill the boiling chamber (ground all transfer equipment, containers, and personnel, see Safety Precautions). Do
not overfill. Close the lid, make sure the lid is centered on the gasket, and secure the lid clamps. Place a clean,
grounded receiving drum under the discharge hose of the Still (or JetVac, if applicable).
4. Verify that the quick-cool water supply is off, and that all cooling water is drained from the quick-cool coil by
opening the drain valve and breather valve.
5. Verify that the condenser water supply is on to the Still. If using a Little Cooler, prepare the Little Cooler for
operation (refer to the Little Cooler Instruction Manual).
6. Set the CYCLE TEMP dial to the desired temperature.
7. Set the CYCLE TIME dial to the desired length of time.
8. Pull the Still’s STOP/START switch to the START position. If the switch is pulled out from a previous run,
push the switch in, wait 5 seconds, then pull the switch to the START position.
9. Adjust the condenser’s water supply until the safety flow switch is satisfied (until the white light stays on).
10. Allow system to operate until the desired time has elapsed, or the solvent has finished processing (a drop in
temperature on the VAPOR TEMP gage indicates near completion of the process). The green light on the
STOP/START switch and the amber light will go out indicating the system is in cool-down mode (this allows
the condenser cooling water to run for an additional hour (to condense any remaining vapors) before
automatically turning the condenser water off.
WARNING:
Never push the STOP/START switch to the STOP position to terminate a process early. Instead, set the
CYCLE TIMER to the 10 MIN position (full counter-clockwise). This will automatically terminate the cycle
in ten minutes, and allows the cool-down mode to engage to help prevent the release of hazardous
vapors.
11. If using the quick-cool feature, turn on the quick-cool water supply for one hour, or until the Still has reached
the desired temperature (100°F or less), turn water supply off and drain quick-cool before starting next cycle.
12. Once all lights have gone out, push the STOP/START switch to the STOP position.
