Start-up and Operation
The LS Series equipment requires minimal operator involvement. Once set up and started, the unit can operate
virtually unattended until the process is complete. See Safety Precautions before operating this unit. Explanation of
each control and setting can be found in Instrumentation and Controls.
CAUTION:
Only process neutral waste solvents with a pH between 6 and 9. Solvents outside of this safe pH range can
cause damage to your LS Series equipment that is not covered under its warranty. Some solvents can
become acidic or basic once heated. Periodically test the dirty solvent as well as the distillate and residue
to verify a safe pH. If your pH is not in the “safe zone,” it must be neutralized. Consult your solvent
supplier for recommendations on testing the pH and pH correction.
LS-15E/55E 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. Turn on the condenser’s water supply. 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. Pull the Still’s STOP/START switch to the START position.
8. Adjust the condenser’s water supply until the safety flow switch is satisfied (until the green light on the
STOP/START button stays on).
9. Allow system to operate until solvent is no longer processing or until desired time has elapsed. Push the
STOP/START switch to the STOP position. Allow the condenser cooling water to run for an additional hour (to
condense any remaining vapors) before turning the condenser water off.
10. 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.
