Service Safety Precautions 

 

Always ensure that only authorized technicians service the refrigeration, 
vacuum and electrical systems. 

 

If performing any electrical maintenance, always disconnect the power at 
the main disconnect. 

 

If the refrigeration system must be operated with access panels removed 
(for diagnostic purposes only), stay clear of moving fan blade. 

 

Always practice team lifting when moving heavy equipment. 

 

After servicing, verify that all access panels or covers are in place before 
resuming normal operation of the equipment. 

 

Routine Maintenance Schedule 

 

Under normal operation, the Freeze Dryer requires little maintenance.  The 
following maintenance schedule is recommended: 

 
As needed: 

 
1.

 

Clean up all spills; remove liquids from the chamber. 

2.

 

Clean lid and gasket using soft cloth, sponge or chamois and a mild, non-
abrasive soap or detergent. 

3.

 

Check oil level of the vacuum pump.  It should be between MIN and MAX.  If 
the oil level is less than an inch (25.4 mm) above MIN, add oil to proper level. 

4.

 

If oil shows cloudiness, particles or discoloration, drain the pump and replace 
with fresh oil. 

5.

 

Utilization of acids requires immediate cleaning and neutralization after a 
run or physical damage to the collector chamber and collector coil will 
result.
