 Rubber and plastic components that have been exposed to damaging
compounds should be removed and flushed with water.
 The oil in the vacuum pump should be checked often. It must be changed if it
is cloudy, shows particles or is discolored. The useful life of vacuum pump oil
can be extended if the vacuum pump is operated for an extended period of time
after a freeze dry run. This allows contaminants to be purged from the hot oil.
This must be done with the inlet to the pump blocked off to prevent air from
free flowing through the pump. This is accomplished by closing all sample
valves on a clean, dry freeze dry system and turning on the vacuum pump. If
the pump is operated at an elevated vacuum level (> 10mBar), oil may be
expelled from the pump and damage could occur.
Another way to extend the life of the vacuum pump is to install an optional
secondary trap in the line between the Freeze Dryer and the vacuum pump.
