LS SERIES STILLS: BASIC TROUBLESHOOTING TIPS CONTINUED…
PROBLEM
: Stilbags break or melt during a cycle or while lifting out residue.
POSSIBLE CAUSES:
Temperature too hot. The standard temp Stilbags will become brittle if overheated. Try the hi-temp Stilbags.
Stilbag used too long. The Stilbag is designed for a maximum of up to 16 hours and for a single use only.
Chemical incompatibility. The Stilbags are made of “Nylon 6” and “Nylon 66.” Check compatibility with your
solvent supplier.
Acid or caustic attack. The Stilbags are designed for use with solvents/residues with a pH between 6 and 9.
Residue too heavy. The dirty/waste solvent should contain no more than 20% solids.
PROBLEM: Unit(s) will not turn on (no lights come on).
POSSIBLE CAUSES:
No power to the Still. Verify the electrical power/connections to the Still.
Blown fuse inside the Still’s control box (System II units only). Replace fuse. This would indicate an electrical
power surge or other problem with the circuitry (consult factory).
Flow switch not engaged (LS-15E and LS-55E only). Verify proper condenser water supply. Clean or service the
flow switch.
Controls have not reset (LS-15E and LS-55E only). Push the STOP/START switch to the STOP position for at
least five (5) seconds before pulling the switch back out.
PROBLEM: Only the green light comes on (System II only). Still not heating.
POSSIBLE CAUSES:
Flowswitch not engaged. Verify proper condenser water supply. Clean or service the flowswitch.
PROBLEM: Only the white light comes on when the STOP/START switch is pulled (System II only).
POSSIBLE CAUSES:
Controls have not reset. Push the STOP/START switch to the STOP position for at least five (5) seconds before
pulling the switch back out.
