Vacuum Pump Connection
A vacuum pump as described in Chapter 2: Prerequisites is required to operate
your Freeze Dry System properly. The Freeze Dryer is equipped with a 3/4" ID,
heavy wall, vacuum hose for connecting the collector chamber to the vacuum
pump.
Make certain that the oil in the vacuum pump is at the proper
level.
Place the vacuum pump near the benchtop Freeze Dryer models. For console
models, from the back of the unit, place the vacuum pump on the floor of the
cabinet.
TO MAXIMIZE THE STABILITY OF THE CONSOLE FREEZE
DRYER, POSITION THE VACUUM PUMP AS CLOSE TO THE
CENTER OF THE CABINET FLOOR AS POSSIBLE.
Connect the vacuum pump power cord to the receptacle on the back of the cabinet
labeled “vacuum pump.” If the vacuum pump has an off/on switch, turn the switch
on. The vacuum pump will be controlled by the Freeze Dryer. Connect the
vacuum pump inlet port to the vacuum tube on the back of the cabinet with the
vacuum hose and clamps provided. If necessary, cut the hose to proper length to
allow for gentle bends without kinks.
Models rated for use on 230V have a reverse IEC connector for attaching the
vacuum pump power cord. A plug is supplied that can be installed on the vacuum
pump power cord if necessary.
Electrical Connection
Plug the power cord into the receptacle on the back of the Freeze Dryer and plug
the other end into a suitable power receptacle.
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 FreeZone Freeze Dry System that are susceptible to
degradation are as follows:
