7.
VERIFY THE VACUUM PUMP VOLTAGE SETTING AGREES WITH
THE FREEZE DRYER VOLTAGE SHOWN ON THE SERIAL
NUMBER LABEL. Reconfigure if necessary (see vacuum pump
instructions).
8.
Connect the vacuum pump power cord to the receptacle labeled “vacuum
pump” on the back of the Freeze Dryer. Models rated for use on 230V
have a reverse IEC receptacle for attaching the vacuum pump power cord.
9.
If the vacuum pump has an ON/OFF switch, turn the switch ON. The
vacuum pump will be controlled by the Freeze Dryer.
IT IS HIGHLY RECOMMENDED THAT AN OIL MIST
EXHAUST FILTER BE INSTALLED ON ROTORY VANE
VACUUM PUMPS TO MINIMIZE OIL MIST EXITING THE
PUMP. AN OIL RETURN KIT CAN ALSO BE USED IN
CONJUNCTION WITH THE EXHAUST FILTER TO RETURN
TRAPPED OIL BACK TO THE VACUUM PUMP.
Electrical Connection
Make sure that the outlet that you intend to use meets the voltage and amperage
requirements listed on the serial tag of the Freeze Dryer. Plug the power cord into
the receptacle on the back of the Freeze Dryer and plug the other end into a
suitable power outlet. It will take approximately 90 seconds for the operating
system to fully load.
Chemical Resistance of Freeze Dryer
Components
The FreeZone Freeze Dry System is designed to be chemically resistant to most
compounds that are commonly used in freeze drying processes. However, by
necessity, the freeze dryer is comprised of a number of different materials, some of
which may be attacked and degraded by certain chemicals. The degree of
degradation is dependent on the concentration and exposure duration. Some of the
major components of the Freeze Dryer that are susceptible to degradation are as
follows:
