INTRODUCTION
Congratulations on your purchase of a Labconco FreeZone®
Freeze Dry System, which is designed for laboratory lyophilization
procedures. The refrigerant used in the refrigeration system is
CFC-free so it will not endanger the environment. The unit is easy
to install and maintain. Proper care and maintenance of this
product will result in many years of dependable service.
Freeze Dry Process
Freeze drying is an important process in sample preparation and
for the preservation and storage of biologicals, pharmaceuticals
and foods. Of the various methods of dehydration, freeze drying
(lyophilization) is especially suited for substances that are heat
sensitive. Other than food processing (e.g., coffee, whole dinners),
freeze drying has been extensively used in the development of
pharmaceuticals (e.g., antibiotics) and preservation of biologicals
(e.g., proteins, plasma, viruses and cell lines). The nondestructive
nature of this process has been demonstrated by the retention of
viability in freeze dried viruses and microorganisms.
Freeze drying is a process whereby water or other solvent is
removed from frozen material by converting the frozen water
directly into vapor without the intermediate formation of liquid
water. The basis for this sublimation process involves the
absorption of heat by the frozen sample in order to vaporize the
ice; the use of a vacuum pump to enhance the removal of water
vapor from the surface of the sample; the transfer of water vapor to
a collector; and the removal of heat by the collector in order to
condense the water vapor. In essence, the freeze dry process is a
balance between the heat absorbed by the sample to vaporize the

Chapter 1: Introduction
ice and the heat removed from the collector to convert the water
vapor into ice.
Freeze Dry Rates
The efficiency of the freeze drying process is dependent upon the
surface area and the thickness of the sample, the collector
temperature and vacuum obtained, the eutectic point and solute
concentration of the sample. It is important to remember these
factors when trying to obtain efficient utilization of your freeze dry
system. A listing of selected materials and their approximate
drying times are shown in Table 1 for your reference.

*Total sample quantities are contingent on various freeze dryer capacities.
Up to the point of overloading the system, the greater the surface
area of the sample, the faster the rate of freeze drying. By contrast,
for a given surface area, the thicker the sample the slower the rate
of freeze drying. This is based on the fact that the heat of
sublimation is usually absorbed on one side of the frozen sample
and must travel through the frozen layer to vaporize water at the
other surface. In addition, as the sample is freeze dried, the water
vapor must travel through the layer of dried material. The thicker
the sample, the greater the chance that the dried layer may collapse
which would cause an additional decrease in the rate of freeze
drying.
The surface area and thickness of the sample can usually be
ignored when each sample contains only a few milliliters.
However, for larger volumes, the samples should be shell frozen to
maximize the surface area and minimize the thickness of the

Chapter 1: Introduction
sample. The volume of the freeze dry flask should be two to three
times the volume of the sample.
In order for lyophilization to occur, ice must be removed from the
frozen sample via sublimation. This is accomplished by the
collector and the vacuum pump. The collector, which should be at
least 15 to 20°C colder than the eutectic temperature (melting
temperature) of the sample, traps vapor as ice. Since the vapor
pressure at the collector is lower than that of the sample, the flow
of water vapor is from the sample to the collector. Since this vapor
diffusion process occurs very slowly under normal atmospheric
conditions, a good vacuum is essential to maintain an efficient rate.
In many applications, the maintenance of a vacuum of 0.133 mBar
or less is recommended.
The rate of freeze drying is directly proportional to the vapor
pressure and the vapor pressure is dependent upon both eutectic
temperature and solute concentration of the sample. For example,
a solution of sodium chloride and water would freeze dry at a
slower rate than pure water. The eutectic temperature of a sodium
chloride solution is about –21°C and at this temperature the vapor
pressure is about 1/16 that of water at 0°C. Although the eutectic
temperature is not dependent upon the concentration of sodium
chloride, the vapor pressure of the water would decrease as the
concentration of sodium chloride increased. This is due to the fact
that as the solute concentration increases, less of the surface area of
the frozen sample is occupied by water. In general, most solutions
or biological samples will have a eutectic temperature of –10° to
–25°C. However, if the sample contains a simple sugar such as
glucose or if the sample is animal or plant tissue, the eutectic
temperature may be as low as –30° to –50°C.
Freeze Dry Capacity
The volume of a sample that can be freeze dried at one time is
related to factors discussed previously and the size and design of
the freeze dry system. With any given instrument, the capacity is
based on the surface area of the sample, the eutectic temperature
and concentration of the sample and the rate and amount of heat
transferred to the frozen sample. Of these factors, the eutectic
temperature is the most important factor in determining the amount
of sample that can be freeze dried at one time, particularly when
flasks are used. This is because as the eutectic temperature
decreases, the vapor pressure decreases but the rate of heat
absorption by the sample does not change. This tends to promote
melting of the sample, which leads to a marked increase in vapor

Chapter 1: Introduction
pressure and ultimately overloads the collector and vacuum pump.
Samples that have eutectic temperatures of –20°C or lower should
be placed on the freeze dry system one flask at a time so that the
vacuum in the system may recover before adding another sample
to the system. If the vacuum does not recover, the capacity of the
freeze dry system has been exceeded and the sample should be
removed.
If there is a problem with a particular type of sample melting when
placed on the freeze dry system, dilution of the sample with more
water or providing some insulation around the flask to decrease the
rate of heat absorption by the sample may help. If the eutectic
temperature of the sample is –40 to –60°C, the freeze dry system
selected for use must be equipped with cascade type refrigeration
so that the collector temperature can be cooled to below –75°C, or
a dry ice/solvent trap may be used between the collector and the
vacuum pump.
Samples Containing Volatile
Substances
In certain cases the solvent in a sample to be freeze dried may
contain volatile components such as acetonitrile, methanol, acetic
acid, formic acid or pyridine. In addition to these substances
having an effect on the eutectic temperature, they may increase the
vapor pressure at the surface of the sample. Also, compared to
water, they will require the absorption of less heat for sublimation
to occur. Hence, samples that contain volatile substances will have
a greater tendency to melt, particularly when placed in flasks or
exposed to room temperature. If a sample containing a volatile
substance tends to melt when placed on a freeze dry system,
dilution of the sample with more water will help keep the sample
frozen. For example, a 0.2M solution of acetic acid is much easier
to freeze dry than a 0.5M solution.

PREREQUISITES
Before you install your Freeze Dryer, you need to prepare your site
for installation. Carefully examine the location where you intend
to install your Freeze Dryer. You must be certain that the area is
level and of solid construction. An electrical source must be
located near the installation site.
Carefully read this chapter to learn:
•
•
the electrical supply requirements.
the vacuum pump requirements.
Refer to Appendix C: Freeze Dryer Specifications for complete
Freeze Dryer electrical and environmental conditions,
specifications and requirements.
Electrical Requirements
The Freeze Dryer requires a dedicated electrical outlet. This outlet
requires a 20 Amp circuit breaker or fuse for models rated at 115V
(60 Hz). An outlet equipped with a 15 Amp circuit breaker or fuse
is required for models rated at 230V (50/60 Hz). The power cord
on 115V models is equipped with a 20 Amp NEMA 5-20P plug.
The power cord on 230V models is equipped with a NEMA 6-20P
plug. If this does not match with the available receptacle, remove
this plug and replace it with an approved plug of the suitable style.
Product Service Domestic 1-800-522-7658, Internationa 816-333-8811

Chapter 2: Prerequisites
Location Requirements
The Freeze Dryer should be located in an area that provides an
unobstructed flow of air around the cabinet. This air cools the
refrigeration system. The refrigeration system draws air in through
the sides and exhausts it through the rear. A minimum of 3" must
be allowed between the rear and both sides of the Freeze Dryer and
adjacent wall surfaces. Restriction of airflow during operation
could adversely affect performance.
Refer to Appendix C: Freeze Dryer Specifications for dimensional
drawings of the Freeze Dryer.
Vacuum Pump Requirements
A vacuum pump must be provided by the user. A vacuum pump
with a displacement of 144 liters per minute and 0.0002 mBar
ultimate pressure is adequate for most samples. The inlet fitting on
the vacuum pump must be suitable for 3/4" ID vacuum hose,
which is provided. It is recommended that the vacuum pump is
equipped with an exhaust filter to minimize oil mist exhausting
from the vacuum pump. The operating vacuum level may be set
on the Freeze Dryer. The higher the pressure is set, the more likely
it is that oil mist will be exhausted.
Vacuum pumps used with 115V models should be equipped with
an 115V, 15 Amp NEMA 5-15P plug. Vacuum pumps used with
230V models should be equipped with a reverse IEC plug. This
plug is included with 230V models. This will allow the vacuum
pump to be plugged into the receptacle on the back panel of the
freeze dryer. See Appendix D: Freeze Dryer Accessories for
vacuum pumps available from Labconco.
Chamber or Manifold
Requirements
A freeze drying chamber is not included and must be purchased
separately. These allow samples to be attached to the Freeze
Dryer. See Appendix D: Freeze Dryer Accessories for available
chambers and manifolds.

Chapter 3: Getting Started
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.
Remove the front stainless steel panel or lower rear panel from the
Freeze Dryer. The front panel is removed by placing a flat blade
screw driver into the rectangular hole in the center of the kick
panel. Pivot the handle downward to disengage the latch and
simultaneously pull the lower panel forward.
Place the vacuum pump inside the cabinet. Connect the vacuum
pump power cord to the receptacle on the back of the cabinet
labeled “vacuum pump.” 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. 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
inside the cabinet near the front with the vacuum hose and clamps
provided. If necessary, cut the hose to proper length to allow for
gentle bends without kinks.

be positioned directly above the 3-inch port on the top of the
Freeze Dryer. Follow the instructions supplied with the selected
accessory.
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:

•
Most common compounds used in freeze drying processes, if
allowed to enter the vacuum pump, will degrade the oil and
cause damage to the vacuum pump.
•
Sugars and proteins typically will have minimal negative effect
on any of the materials of construction.
When using compounds in the Freeze Dryer that are hostile to the
materials of construction, it is imperative the equipment is
thoroughly cleaned after use.
Product Service: Domestic 1-800-522-7658, International 816-333-8811
15
Chapter 3: Getting Started
•
•
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. Contact Labconco for ordering information.
With prudent maintenance the FreeZone Freeze Dry System will
provide years of service. Warranty on the affected parts will be
voided if maintenance has been obviously neglected. If you have
questions about using specific compounds in the Freeze Dryer,
contact Labconco Technical Service at 1-800-821-5525 or 816333-8811 or e-mail: [email protected]
!
Solvent Safety
Precautions
Solvents used in the Freeze Dryer may be
flammable or hazardous to your health. Use
extreme caution and keep sources of ignition
away from the solvents. When using flammable
or hazardous solvents, the vacuum pump must
be vented to a fume hood.
Hazardous materials such as strong acids or
bases, radioactive substances and volatile
organics must be handled carefully and
promptly cleaned up if spilled. If a sample is
spilled in the collector chamber it must
immediately be cleaned up.

Chapter 4: Using Your Freeze Dryer
Operation Checklist
The following checklist should be followed prior to each use of your
Freeze Dryer:
1. Wipe the interior of the collector chamber with a soft cloth or paper
towel to remove any accumulated moisture.
2. Check the collector chamber drain hose to ensure that the hose is free
of moisture and that the drain plug is securely installed. The Freeze
Dryer will not start if moisture is detected.
3. Using a soft, lint-free cloth or paper towel, wipe the collector chamber
lid gasket to remove any dirt and contaminants that could cause a
vacuum leak. Vacuum grease is not required on the lid gasket to
obtain a proper vacuum seal.
4. Remove the accessory drying chamber or manifold from the
connection port and using a soft, lint-free cloth or paper towel, wipe
the port gasket and sealing surfaces of the drying chamber/manifold to
remove any dirt and contaminants that could cause a vacuum leak.
Reinstall the drying chamber or manifold on the port. Vacuum grease
is not required on the port gasket to obtain a proper vacuum seal.
5. Inspect each sample valve on the accessory drying chamber or
manifold and check for any visible damage and for improper
installation that might cause a vacuum leak. Also check that each
sample valve is closed or in the “vent” position.
Vacuum Pump Ballast Setting
Most vacuum pumps are equipped with a gas ballast mechanism. The
freeze dry process requires high vacuum. Therefore, it is recommended
that the gas ballast be closed during the operation of the Freeze Dry
System. If the gas ballast is left open for extended periods of operation,
the oil can be pumped out the exhaust, causing the pump to fail.
Purge Valve
The optional purge valve is installed between the Freeze Dryer collection
chamber and the vacuum pump. When the green LED above the PURGE
switch is illuminated, the purge valve is closed and the vacuum pump is
isolated from the Freeze Dryer collection chamber.
During Freeze Dryer start-up, the refrigeration system pulls the collector
coil down to temperature. While the collector coil cools, the purge valve
can be closed and the vacuum pump allowed to
run. This allows the vacuum pump oil to warm, which will evaporate and
expel condensed solvents from the oil. When the collector coil is down to
Product Service: Domestic 1-800-522-7658, International 816-333-8811
21
Chapter 4: Using Your Freeze Dryer
temperature and the freeze dry process is started, the warm pump oil is
less likely to condense solvent vapors that are not trapped by the collector
coil. When the Freeze Dryer is operated in the Automatic Mode, the
purge valve and vacuum pump will operate automatically to perform this
function. In the Manual Mode the user must manually activate the purge
valve and vacuum pump to perform this function.
During shut down the vacuum pump can be run for several minutes with
the purge valve closed. This will allow the warm pump oil to evaporate
and expel solvent vapors that condensed in the pump oil during the freeze
dry process. Whether the Freeze Dryer is run in the Automatic Mode or
the Manual Mode, the user must manually activate the purge valve and
vacuum pump to perform this function.
If power to the Freeze Dryer is interrupted during the freeze dry process,
the purge valve will open during the power outage, and the vacuum bleed
valve will open to allow atmospheric air to enter the system.

Chapter 4: Using Your Freeze Dryer
Setting the Operating Vacuum Level
The vacuum level may be set by the user to optimize the freeze dry
process. Normally, the sublimation rate will increase if there is less
vacuum (a higher pressure) in the Freeze Dryer. A good starting place is
to set the vacuum so its level is equivalent to about 10°C colder than the
eutectic or collapse temperature of the sample. Adjustments to the
vacuum level must be made for various freeze drying conditions. Factors
that must be considered are whether the sample is freeze dried on heated
shelves or in glassware attached to manifold valves, the volatility of the
sample itself, the size of the sample and the heat energy supplied to the
sample.
When the vacuum control is set to operate at less vacuum, the ice holding
capacity of the collector may be decreased. This can be improved in noncascade models by installing a baffle in the collector. See Appendix D
Freeze Dryer Accessories for the baffle part number. See the section titled
Baffle in this chapter for proper installation.
Some guidelines for setting the Freeze Dryer are shown below. These
show pre-freezing temperatures and vacuum levels. Exact protocols must
be determined by the user for the specific samples that are being freeze
dried.

Pre-Freezing Samples
Appropriate containers for freeze drying include ampules, serum bottles,
and wide mouth freeze drying flasks. Shell freezing of samples is
recommended for wide mouth freeze drying flasks. Smaller samples in
ampules and serum bottles may be frozen in a freezer. The sample
container size should always be at least two to three times the sample size
(i.e., 40 ml samples should be prepared in 80 ml containers or larger). The
temperature required for pre-freezing is dependent on the characteristics of
the sample. Pre-freezing temperature typically is at least 10° to 20°C
below the eutectic or collapse temperature of the sample.

Chapter 4: Using Your Freeze Dryer
Adding Sample
The following procedure should be followed when using sample valves in
the freeze dry process:
1. Connect a pre-frozen sample to a sample valve on the drying chamber or
manifold using an adapter. Turn the plastic valve knob to the “VACUUM”
position to open the valve. The bevel on the knob should be positioned
toward the sample port to apply vacuum to the sample.
Bevel in “vent” position
Vent/Backfill Port
Bevel in “vacuum”
position
Adapter
2. Before adding another sample, allow system vacuum to return to 0.133
mBar or lower. Any combination of valves and sample sizes may be
utilized at one time provided that the system vacuum and collector
temperature remain sufficiently low to prevent melting of the frozen
sample.
3. When all the frost has disappeared from the outer surface of the
sample container and no cold spots can be detected by handling the
container, the sample is nearly dry. To be certain of low final moisture
content, dry the sample for several hours past this point.
4. To remove a container after drying is complete, turn the plastic knob
on the valve to the “VENT” position, which closes the valve and vents
the container. Should backfilling with an inert gas be required,
connect the gas supply line to the vent port on the valve before turning
the plastic knob on the valve to vent position. The sample container
may now be removed. In the vent position the bevel on the valve knob
should point away from the sample port.

Chapter 4: Using Your Freeze Dryer
5. Ampules may be flame sealed while connected to a valve by using a
sealing torch. Care must be taken not to burn the valve. An insulation
material placed between the valve and the torch is recommended.
Shut Down
At the end of a run or when a sufficient amount of condensate accumulates
on the collector coil to obstruct the flow of vapor to the collector chamber,
the Freeze Dryer should be defrosted. First, release system vacuum by
turning the plastic knob on a valve to the open position or by pulling the
collector chamber drain plug out of the drain hose. Now press the
Vacuum Switch on the control panel to turn the vacuum pump OFF. Press
the Refrigeration Switch next to the illuminated LED to turn OFF the
refrigeration system. Turn OFF the Main Power Switch on the left hand
side of the cabinet.
After a run is complete, it may be desirable to purge contaminants from
the vacuum pump oil. This can be accomplished by first closing the purge
valve by pressing the purge switch. The LED will illuminate. Then turn
on the vacuum pump by pressing the vacuum switch, let the pump operate
for an extended period of time.
Defrosting
The following procedure should be followed when defrosting the collector
coil:
1. Pull the collector chamber drain hose out from the front panel of
the unit and remove the drain plug. Place the drain hose in a
suitable container to collect the condensate that will be defrosted
off the collector coil.
2. Press the DEFROST switch on the control panel. The green LED
above that switch will illuminate. Allow unit to operate in this
condition until all condensate is defrosted from the collector coil.
Dispose of the liquid appropriately.
3. Lift out the ice plug after it has melted sufficiently to be removed
without force.
4. Flush the collector chamber with water and wipe chamber dry.
5. If rapid defrost is desired, pour warm water into the collector
chamber covering no more than the bottom 2 coils. If excess water
is added it can enter the vacuum port and drain into the
vacuum pump.
Product Service: Domestic 1-800-522-7658, International 816-333-8811
29
Chapter 4: Using Your Freeze Dryer
6. Press the DEFROST switch, the green LED will be off. Reinstall
the drain hose plug and slide drain hose back into cabinet through
the front panel. Dispose of the liquid appropriately.
!
Utilization of acid requires immediate cleaning and
neutralization after defrost or physical damage to the
collector chamber and collector coil will result.
Do not attempt to chip ice from the collector coil as
damage may occur to the coil.
Never attempt to start the vacuum pump when there is
liquid in the collector chamber. This could result in
damage to the vacuum pump.
Operating the Shell Freezer
The optional built in shell freezer is designed for shell freezing samples in
flasks in preparation for freeze-drying.
Follow the steps below each time you use the shell freezer to obtain
optimum performance:
1. Check that the solvent bath drain plug is securely installed in the drain
hose.
2. Remove the bath compartment cover and add solvent to the bath
compartment. Commonly used solvents are methanol or ethanol.
Recommended solvent depth is ¼" to ½" above the top of the rollers
(approximately 2 liters).
!
If flammable solvents are used in the shell freezer bath,
be sure to keep away from open flame.
3. Press the panel switch labeled SHELL FREEZE. The green LED
above the switch will illuminate. The shell freezer refrigeration
module will start and the bath rollers will begin rotating. The LCD
display will show the shell freezer bath temperature.
4. Fill a freeze dry container no more than ½ full with sample and stopper
the container top. Lay the container on the rollers in a horizontal
position. Replace the bath compartment cover during shell freezing.
5. When the sample is completely frozen in the container, remove the
container from the bath compartment and freeze dry the sample or
place it in a suitable storage freezer for future freeze-drying.
30
Product Service: Domestic 1-800-522-7658, International 816-333- 8811
Chapter 4: Using Your Freeze Dryer
6. Press the SHELL FREEZE switch to turn shell freezer off.
7. If the Shell Freezer is to be used for cold bath operation, additional
solvent may be added to submerge small flasks. Do not fill pan more
than 2 inches below the top of the stainless steel pan with vessels
submerged. Allow additional time for larger volumes of solvent to
pull down in temperature.
8. Always drain flammable solvents from the bath when the shell freezer
is not in use and store the solvent in a suitable container. This is
accomplished by first pulling the drain hose out of the front panel of
the unit and then removing the drain plug. Place the hose in a suitable
container to collect the solvent.

Operating the Vacuum Drying
Chamber
The built-in drying chamber is designed for freeze drying small samples,
either in bulk or in small containers such as vials or 96 well plates. It may
be used in conjunction with other drying accessories that are mounted on
top of the Freeze Dryer or independently. If a manifold or chamber is
mounted to the Freeze Dryer and is not in use, close all of its valves. If no
drying accessory is installed on the Freeze Dryer, place the supplied
stopper in the center of the 3.0 accessory port that is on the top of the
Freeze Dryer to seal the vacuum system. Follow the steps below to
operate the built-in drying chamber.
1. Start the Freeze Dryer. Position the Vacuum Chamber valve on the
top of the Freeze Dryer to the VENT position. Turn on the
refrigeration in the Freeze Dryer in the MAN or AUTO mode
according to the instructions in this manual. If the sample will be
prefrozen in the collector chamber, the Freeze Dryer must be started in
the MAN mode.
2. Set the Drying Chamber temperature according to the Set Up
instructions in this manual. The set temperature should be lower than
the eutectic temperature of the sample.
NOTE: The Drying Chamber is NOT refrigerated. If the operating
temperature is set below ambient, the only source cooling the chamber
is the sample itself.

31
Chapter 4: Using Your Freeze Dryer
3. Press the switch marked Shell Freezer/Vacuum Chamber to actuate the
heater.
4. Freeze the sample. Before the freeze dry process can occur, the
product to be freeze dried must be in a frozen state. This can be done
in a separate freezer or in the Freeze Dryer collector chamber.
5. Load the samples. The Freeze Dryer collector temperature must be –
40°C or colder. Replace the chamber lid.
6. Start primary drying. Turn the vacuum control valve on the top of the
Freeze Dryer to VACUUM. Start the vacuum pump if the Freeze
Dryer was started in the MAN mode.
7. Start secondary drying. After all the free moisture is removed in the
primary drying phase, the temperature of the chamber may be
increased. Do this according to the instructions in the Set Up section
of this manual.
8. Shut Down. After completion of the freeze dry procedure:
a. Press the Shell Freezer / Vacuum Chamber Switch to turn off
the chamber heater.
b. Release vacuum in the chamber by turning the valve on the top
of the Freeze Dryer to VENT.
c. Remove the sample.
d. Release vacuum from the Freeze Dryer by either opening the
Vacuum Chamber valve when the chamber lid is off or by
removing the drain plug or by opening a valve on chamber or
manifold mounted on top of the Freeze Dryer. Turn off the
vacuum pump.
e. Turn off the Freeze Dryer, defrost and drain the chamber per
instructions in this manual.
Alarms
A number of unusual events may occur during a lyophilization procedure
that can adversely effect the operation of the Freeze Dryer. If an event
occurs, the alarm indicator will flash and the beeper will sound.
The beeper will automatically mute itself after one minute. The specific
alarm can be identified by pressing MENU. Pressing MENU multiple
times will display multiple alarms if they have occurred. The following
“out of specification” conditions will initiate an alarm:
Power Failure
If a power failure occurs during a Freeze Dry process, the vacuum control
valve will allow air to bleed into the Freeze Dryer System.
32
Product Service: Domestic 1-800-522-7658, International 816-333- 8811
Chapter 4: Using Your Freeze Dryer
If the failure is of a short duration and the collector does not warm up
excessively, when power is restored, the Freeze Dryer will restart and
resume operation of the refrigeration and vacuum systems. If the power
failure lasts for a longer duration and the collector warms above safe
limits, when the power is restored, the Freeze Dryer will not restart by
itself. This prevents melted sample from being drawn into the collector
and prevents liquid from being sucked into the vacuum pump. When
power is restored, the alarm indicator will flash and the alarm beeper will
sound. When the MENU button is pressed the display will show
POWER FAIL
HOLD SELECT TO CLEAR IT
Press and hold SELECT for five seconds until the error message is cleared
from the display.
Line Voltage Out of Range
If the voltage supplied to the Freeze Dryer varies beyond allowable limits,
the alarm will be activated. When an alarm occurs, press MENU and the
display will show:
LINE VOLTAGE ERROR
The alarm will self-cancel when the proper voltage is restored. The high
and low alarm points are preset at the factory to correspond to the normal
allowable voltage variations based on the nominal voltage specified for the
freeze dryer. Some models may be operated outside the normal voltage
limits. See Appendix C.
If necessary, the high and low alarm points may be adjusted for these
models. See Chapter 8.
Temperature Out of Range
An alarm will be activated if the collector temperature rises above –40°C.
If this occurs, the display will show:
COLLECTOR TEMPERATURE
HOLD SELECT TO CLEAR IT
Press and hold SELECT for five seconds until the error message is cleared
from the display.

Chapter 4: Using Your Freeze Dryer
Service Vacuum Pump
The vacuum pump normally plugs into the vacuum pump electrical
receptacle on the back of the Freeze Dryer. When the Freeze Dryer has
accumulated a total of 1000 operating hours, the alarm indicator will flash.
Press MENU to display the alarm:
CHANGE VACUUM OIL
HOLD SELECT TO CLEAR IT
Press and hold SELECT for five seconds until the error message is cleared
from the display.
This will reset the 1000 hour timer. It may be necessary to service the
vacuum pump more frequently than every 1000 hours depending on the
operation of the Freeze Dryer. The pump oil should be regularly
monitored to verify that it is clean.
Moisture in Collector
If there is liquid in the collector chamber and either a REFRIGERATION
button or the VACUUM button is pressed, neither function will start and
an alarm will be activated. When MENU is pressed, the display will
show:
MOISTURE IN COLLECTOR
When the collector is drained, the alarm will self-cancel.
This feature prevents the inadvertent start of the vacuum pump when
liquid is in the collector and thereby can extend the life of the vacuum
pump. A few drops of liquid may remain in the drain hose after draining.
When the vacuum pump is started these drops may be sucked into the
collector chamber. This is normal.

CHAPTER 5
MAINTAINING YOUR
FREEZE DRYER
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.
6. Check the collection chamber for condensed or frozen solvents
and dispose of appropriately. Completely empty the collector
chamber before the next run or before attempting to start the
vacuum pump.
7. If sample valves leak or stems become difficult to turn, pull the
stem out of the rubber valve body and apply a thin coat of
vacuum grease to the stem. Reinsert the stem into the valve
body.
Product Service: Domestic 1-800-522-7658, International 816-333-8811
35
Chapter 5: Maintaining Your Freeze Dryer
Monthly:
1. The rubber components on the Freeze Dryer may eventually
deteriorate and require replacement. The effective life of
rubber parts depends upon both their usage and the surrounding
environment. Check all rubber hoses and gaskets and replace
any that show signs of hardening, permanent set or
deterioration.
2. Using a soft cloth, sponge or chamois and a mild, non-abrasive
soap or detergent, clean the acrylic chamber lid.
3. Using a soft cloth, sponge, or chamois and a mild, non-abrasive
soap or detergent, clean the exterior surfaces of the Freeze
Dryer. Liquid spray cleaners and polishes may be used on the
exterior surfaces. Do not use solvents to remove stains from
the exterior surfaces as they may damage the finish.
Annually:
1. Every 12 months, or more often if the Freeze Dryer is operated
in a dusty environment, the refrigeration system condenser
should be cleaned. Using a vacuum cleaner with brush
attachment, clean the condenser to ensure proper airflow for
peak performance.

CHAPTER 7
TROUBLESHOOTING
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.
Labconco Freeze Dry Systems that are clean, dry and without
samples attached should reach a vacuum of 0.133 mBar within 10
minutes and should achieve an ultimate vacuum of 0.033 mBar
within 18 hours when the refrigeration is operating. If the Freeze
Dryer does not obtain a satisfactory vacuum, perform the following
maintenance tests.
I. 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. 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.
42
Product Service Domestic 1-800-522-7658, International 816-333-8811
Chapter 7: Troubleshooting
If vacuum problems continue, consider obtaining a second vacuum
gauge capable of reading a vacuum of 0.010 mBar. It is often
useful in determining if the vacuum pump is operating properly
and the vacuum sensor reading is accurate.
4. Isolate the pump by disconnecting the vacuum hose from
the Freeze Dryer. Deadhead the pump by inserting the
vacuum sensor from a secondary vacuum gauge into the
end of the vacuum hose and observe the vacuum reading
obtained. Confirm that the pump is capable of achieving an
ultimate vacuum less than 0.010 mBar or approximately 10
microns. If an inadequate vacuum reading is obtained, the
pump has most likely failed and may need to be replaced or
rebuilt.
II. Gaskets, Tubing, Connections, Sample
Valves
1. Check all sample valves on the drying chamber/manifold
and ensure all valves are closed or in the vent position.
Check to ensure all fittings are tight and sealed properly
against the chamber. Inspect valves for cracks or cuts.
2. Inspect gasket(s) for cracks or defects. Ensure the gasket is
clean. Apply a thin coat of vacuum grease to the gasket.
Keep in mind too much vacuum grease can actually cause
leaks.
3. Check the drain line and ensure the drain plug is installed
and the tube appears to be in good condition.
4. Check all rubber vacuum tubing for signs of deterioration
or cracking.
5. Check all connections and make sure they are secure and
leak tight.
6. When checking the sample valves, pull as much vacuum as
possible. If a vacuum indication is displayed, wiggle or
rotate the valves and watch the gauge for any fluctuations.
Fluctuations can indicate a potential vacuum leak. If the
valve seems to be in good condition, remove the valve and
apply a thin coat of vacuum grease to the stem and the
outside sealing surface of the valve body, and reinstall the
valve. DO NOT APPLY VACUUM GREASE TO THE
SAMPLE VALVE GASKETS, WHICH SEAL TO THE
WALL OF THE DRYING CHAMBER. If the valve still
seems to be the source of the problem, remove the valve
and stopper the hole with a rubber stopper. Continue
checking the other valves.

Chapter 7: Troubleshooting
7. Make sure that the sample valve bulkhead nuts are tight.
Either tighten by hand or use the wrench supplied with
chambers. To use the wrench, first remove the knob and
stem assembly and also the valve body. The pins on the
wrench fit into the round holes of the nut. The nut should
be snug, but avoid over-tightening. Replace the valve
body, knob and stem assembly.

The following test allows you to check the pump and the
connections from the pump to the vacuum tube.
1. Place a rubber stopper in the vacuum port in the left side of
the collector chamber and another in the drain port in the
bottom.
2. Restart the vacuum system and check your vacuum
indication. Insufficient vacuum indicates a bad pump or a
leak in the connections from the pump to the side of the
chamber.

The following test is used to check the collection chamber
integrity. The figure below points out potential areas to locate a
leak:
Collector
Chamber
Areas for
Potential Leaks
1. Remove the stopper from the side of the chamber and place
a freeze dry flask over the connection port.
2. Fill the collection chamber with approximately 2 inches of
water, enough to cover all fittings. Replace the collection
chamber lid and turn on the vacuum pump. Allow the
vacuum pump to run for approximately 5 to 10 seconds. (If
the vacuum pump is left on, the water will begin to boil and
the test will not be effective). Look inside the chamber for
any bubbling while the pump is running and after you shut
the pump off.
3. If bubbling is observed around the bulkhead fittings, access
the bottom of the chamber and remove the insulation.
Tighten the appropriate fitting by placing a wrench on the
fitting inside the chamber and use a second wrench to turn
the nut on the bottom of the chamber. Be careful not to
damage the evaporator coils or the brazed joints to the
refrigeration system. Once the fitting is tightened, perform
the test again. Should the bubbling still be present, loosen
the bulkhead fittings and apply vacuum grease to the Orings, then reassemble and test.

4. If bubbling was observed on the chamber surface, the
chamber must be replaced. This type of leak cannot be
successfully repaired. The leading cause of a chamber
surface leak is corrosive residue left in the chamber after
use.
Refrigeration Module Operation
Under a no-load condition, the FreeZone Single Stage Freeze Dry
System can achieve a collector temperature of -47°C or lower
when the system is under vacuum, within 40 minutes when the
vacuum pump is running, depending on ambient temperature and
humidity. Cascade Freeze Dry Systems will achieve -81°C within
40 minutes.
Cascade Systems (those that operate @ -81°) consist of two vaporcompression refrigeration systems in series connected together via
a heat exchanger. Each system has a compressor, condenser,
capillary tube metering device and an evaporator. During
operation the evaporator of the “high stage” system refrigerates the
condenser of the “low stage” system. This takes place in the heat
exchanger. The low stage and high stage systems are balanced by
design, however, sometimes that balance can be disrupted during
operation and the unit will not function properly. If the unit is
overloaded, or if the unit is defrosted and restarted in a short time
interval, system unbalance is possible. If system unbalance occurs,
turn the Freeze Dryer off and allow the unit to soak at ambient
temperature for 2 to 4 hours.
If any repairs are required on the refrigeration module, contact
your local laboratory supply dealer. If your laboratory supply
dealer is unable to provide assistance, please call Labconco.
Repairs should only be undertaken by a competent refrigeration
technician or through an authorized Labconco service agency.

CHAPTER 8
MODIFYING YOUR
FREEZE DRYER
DISPLAY
Your Freeze Dryer has been carefully calibrated and tested before
shipping, however under certain circumstances it may be necessary
to adjust the calibration of the temperature and/or vacuum display
or to modify alarm points. Adjustments may be necessary if the
Freeze Dryer requires service or if it is operating on a line voltage
outside the voltage range at which the alarm was preset. This
DOES NOT mean that the Freeze Dryer may be operated at a
voltage outside the ranges shown in Appendix C.
Temperature and Vacuum Display
An offset may be added to the collector temperature or vacuum
display. Use an accurate traceable reference to compare the
readings.
Temperature offset may be varied ±5°C in 1°C increments.
Vacuum offset may be varied ±0.020 mBar in 0.001 mBar
increments.
Line Voltage Alarm Points
The Freeze Dryer is designed to alarm if the line voltage varies
more than ±10% from nominal line voltage. Models rated to
operate on 115V are preset to alarm if the voltage drops below
approximately 103V or rises above approximately 127V. Models
rated to operate on 230V will alarm if the voltage drops below
Product Service Domestic 1-800-522-7658, International 816-333-8811
49
Chapter 8: Modifying Your Freeze Dryer Display
approximately 206V or rises above approximately 254V. Some
models are designed to operate below these ranges (see Appendix
C). In these cases it is permissible to lower the low voltage alarm

Fast-Freeze Flasks are specially designed to be easier to
handle, faster to load and more convenient to use than other
freeze dry glassware now in your laboratory. Compatible
with all major brands of laboratory freeze dry equipment,
Fast-Freeze Flasks eliminate the risk of contamination from
vacuum grease, reduce spillage of valuable samples and
require no washers, gaskets or retainers.
How to select Fast-Freeze Flasks for
your Freeze Dry System
Select Fast-Freeze Flasks based on your sample sizes. Flasks
should be filled no more than one-third of their volume so
that maximum surface area is achieved and efficient
lyophilization is assured. A complete Fast-Freeze Flask
includes a rubber top, glass bottom and a supply of filter
paper. Tops, bottoms and filter paper are available separately as replacement components. Adapters are required to
attach flasks to freeze dry valve ports.
