ROUBLESHOOTING

 

 

 
Refer to the following if your Freeze Dryer fails to operate properly.  If the 
suggested corrective actions do not solve your problem, contact Labconco for 
additional assistance. 
 

Vacuum System Performance 

FreeZone

 Triad

 Freeze Dry Systems that are clean and dry and without 

samples attached should reach a vacuum of 0.133 mbar within 30 minutes 
and should achieve an ultimate vacuum of 0.040 mbar within 18 hours when 
the refrigeration is operating.  If the freeze dry system does not obtain a 
satisfactory vacuum, perform the following maintenance tests. 

 

Vacuum Pump 

First make sure that the vacuum pump operates.  If it fails to operate, check 
the electrical connections of the Freeze Dryer to the power source and then 
check the electrical connection of the vacuum pump to the Freeze Dryer.  If 
the vacuum pump has a power switch, make sure that it is turned on.  

Note: 

If the vacuum pump is plugged directly into a wall outlet for 
troubleshooting purposes, the vacuum START button must be initiated 
on the display screen

.  

If the vacuum START button is not initiated the 

vacuum vent valve will remain open and the vacuum reading will remain 
on HIGH.  

If the vacuum is not adequate when the vacuum pump is 

operating, proceed with the following steps: 
 

1.

 

Check the oil and ensure it is clear and clean.  If the oil looks cloudy 
or has any particulates, replace the pump oil.  Sometimes it may be 
necessary to flush the pump with clean oil several times.  To flush the 
pump, run the pump 5 to 10 minutes to allow the oil to warm up.  
Drain the oil and refill with clean oil.  Repeat as necessary. 

 
2.

 

Check the oil level in the pump.  Ensure it is filled to the correct level. 
 

3.

 

Check vacuum hose connections from the pump to the Freeze Dryer 
and try running the unit.
