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.
