DEFECTS 

CAUSES 

REMEDIES 

The solvent bleeds out of the cover 

Worn out gasket 

Replace the gasket 

Vapour manifold is clogged 

Wash manifold and condenser by 
pouring in clean solvent with a funnel 
or by blowing in compressed air 

Vapour condenser is clogged 

Replace the condenser 

The distillate outflow is blocked 

Wash the discharge line by pouring clean 
solvent in the vapour manifold with a 
funnel and blow with compressed air 
Check that the discharge line is not un-
der the distillate level in the collection 
vessel 

The 'RecBag' is damaged 

Working temperature too high 

Reduce the working temperature  
Use 'RecBag T' 

The solvent is acid 

Distil only neutral solvents 

Cover gasket swells 

The boiler cover is opened when the 
machine is still hot 

Wait until the oil temperature has 
sunk under 50 °C, before opening the 
cover 

The cover gasket is not suitable for 
the type of solvent treated 

Mount the suitable gasket 

Smoke comes out from under the cover 

Overheating of the polluting products or 
presence of nitrocellulose 

Reduce the working time and/or temper-
ature. Possibly distil under vacuum with 
the suitable kit (optional) 

Worn out gasket 

Replace the gasket 

The red indicator light switches on  
“ALARM” 

Diathermic oil temperature is higher 
than the maximum allowed one: ther-
mostat of maximum temperature inter-
venes 

Replace the working thermostat and re-
set the maximum thermostat by pushing 
the reset button of the thermostat 

Distillate temperature is over 60 °C  

Verify the correct functioning of the con-
denser and its fan 

Ambient temperature is too high 

Ventilate the room or do not work at 
very warm days 

Ventilator motor burnt out 

Replace ventilator motor 

Vapour condenser dirty on the outside  Clean with a compressed air jet 
The security thermostat of the con-
denser is defected 

Call the producer for the setting or re-
placement of the thermostat 

The red indicator light flashes 
“ALARM” 

The machine has reached 2000 working
