MALFUNCTIONS, CAUSES AND REMEDIES 
Problem: 
Unit is heating up to set temps. 
Unit will recycle off water, alcohol and xylene into one container, second container, first container remains 
empty. 
Initial troubleshooting revealed that the switching module was okay and did not need replaced. 
Possible Solutions: 
Middle thermostat, which controls distillation temp may have become loose within well and is not 
registering temp. 
Middle Thermostat may need replaced. 
To Check: 
Turn unit on heat it without anything in it. Move the middle thermostat back and slowly move to higher 
temp. Watch to see if the indicator light changes from set to distillation temp. If this happens, thermostat is 
okay. 
Thermostat probe may still be out or loose in distillation chamber. Take front cover off of unit, it comes in 
on the top right side of the unit. 
Distillation time lasts much 
longer than 4 hours 
1.  Contaminated solvent 
contains too much water 
2.  Thermal oil level is low 
3.  Thermal oil is old and 
dirty 
4.  Heating elements need 
cleaning 
1.  Replace the solvent 
2.  Add oil 
3.  Change the oil 
4.  Remove and clean with 
solvent 
Heats but does not distill  1. Distilling chamber is dirty 
2.   Solvent distillation temp. is 
higher than set on working 
thermostat 
3. Distillate temperature too high 
4. Thermal oil level is low 
1. Clean chamber 
2. Increase the Working 
Thermostat temp. setting 
3. Change solvent 
4. Add oil 
Red Indicator Light is “ON”  1.   Working temperature is too 
high 
2.   The max. temp. Safety 
 Thermostat intervened 
3.   The distillate Safety 
 Thermostat intervened 
4. Cooling motor not operating 
5. Distilling Condenser scaled 
6.   Maximum Temp. Safety 
Thermostat is defective or out 
of calibration 
Condensing apparatus has 
1. Reduce the working temp 
2. Change the Working 
Thermostat 
4. Replace motor 
4. Clean or replace 
5.   Remove the protective cage 
and clean it with a brush or air 
pressure 
6. Replace Max. Temp. Safety
