WARNING: ANY ELECTRICAL TESTS PERFORMED ON THIS UNIT MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN.
WARNING: BEFORE PERFORMING ELECTRICAL TESTS, UNIT MUST BE REMOVED FROM THE HAZARDOUS AREA.
PROBLEM: No distillate (clean solvent) is being produced.
POSSIBLE CAUSES:
• No power to the unit. Check main circuit breaker and/or electrical supply to the unit.
• Boiling point of solvent is too high (consult the solvent’s MSDS). Use an LS-JrVac attachment for solvents with boiling
points between 300° and 500°F.
• Unit is not level. Install the LS-Jr on an even, level surface.
• Temperature control circuit needs reset. Push the start/stop switch to the “stop” position for a minimum of five (5) seconds
to reset.
• Cooling water flow is insufficient or not cool enough. Verify proper cooling water supply (refer to “Plumbing Connections”
section of this manual).
• Solids content in dirty solvent too high. Process less contaminated solvent.
PROBLEM: A batch takes longer than 8 hours to process.
POSSIBLE CAUSES:
• Boiling point of solvent is too high (consult the solvent’s MSDS). Use an LS-JrVac attachment for solvents with boiling
points between 300° and 500°F.
• Solids content in dirty solvent too high. Process less contaminated solvent.
PROBLEM: Distillate appears dirty or discolored.
POSSIBLE CAUSES:
• Over-filled boiling vessel. Limit each batch to 5 gallons or less.
• Violent boil or “bumping” from water in the dirty solvent. Eliminate water from the waste solvent.
• Unsafe pH. Distilled solvent appears green or blue. Neutralize the solvent to a pH between 6 and 9 (refer to the “Operating
the LS-Jr” section of this manual).
11. Keep the condenser water flowing for an additional 1/2 hour after turning off the LS-Jr. This is to recondense any remaining
vapors from the boiling chamber.
12. Allow the LS-Jr to cool down below 100°F before attempting to remove the lid. This takes approximately 8 hours (over night).
13. Disconnect the hoses from the LS-Jr lid. Using the handles, slowly lift and remove the lid from the top of the boiling chamber.
Set the lid down on a clean, flat surface.
14. Wearing proper eye and skin protection, remove the Stilbag retaining ring and carefully lift out the residue-filled Stilbag. Dis-
pose of residue according to local regulations.
NOTE: Do not attempt to re-use the Stilbag. It is designed only for one batch.
15. Clean out the inside of the LS-Jr’s boiling chamber using a soft, damp cloth. If necessary, a little bit of clean solvent can help
loosen residues. For baked-on residues, use the optional plastic Stilscraper or other plastic utensil.
NOTE: Do not use metal tools to scrape the boiling chamber. Scratching the non-stick coating voids the warranty.
