or lower, after 30 minutes (or if the
screen still says ">2500 mTorr")
check steps 2-11 of this Quick Start
Guide to assure that there are no
air leaks at any location on your
freeze dryer.
• Once you are able to see a
pressure of 500 or lower, you are
ready to start your first batch.
Turn off your freeze dryer and
open the drain valve. This will
release the pressure and allow the
door to be opened so that you can
begin freeze drying your desired
product. Now that the pressure
has been released, close the drain
valve again (or you will not be able
to achieve a vacuum when the
freeze dryer is running.)
• If you are still unable to complete
this test, call Customer Support at
1-800-865-5584 for assistance in
setting up your freeze dryer.

Prepare the material that you
want to freeze dry and place it on
the trays, one layer thick, so that
it can be uniformly warmed by the
shelving unit. Food that is pre-frozen
should go into a cold chamber; To
accomplish this, run the freeze cycle
for 30 minutes before taking your
food out of the freezer and putting it
in the freeze dryer.
15.
Turn the freeze dryer on. The
screen will now prompt you to press
'Proceed' or 'Cancel' within a limited
amount of time. Press 'Cancel' . This
will return you to the home screen.

Place the trays in the shelving
unit inside the freeze dryer; insert
the black pad; close the door and
press "Start."
17.
The material will be frozen in
the freeze dryer for 9 hours. The
vacuum pump should then come on.
If it doesn't, make sure it is plugged
into the back of the freeze dryer.
Make sure the power switch located
on the back of the vacuum pump is
turned on.
18.
When the vacuum pump comes
on it should reduce the pressure in
the food chamber within about 10
minutes. If you can still open the door
after 30 seconds, turn off the vacuum
pump, release the pressure in the
food chamber by opening the drain
valve, open the door, and check the
cleanliness of the rubber gasket. Close
the door and turn the vacuum pump
on. Wait for 1 minute and verify that the
door cannot be opened. If your door is
out of adjustment the gasket may not
be able to make contact with the door.
Readjusting the door may be necessary.
19.
Once the food is frozen, and
when adequate vacuum pressure is
reached (500 mTorr), the heaters on
the shelves turn on and stay on for
a few minutes, then they will turn
off when the pressure rises to 600
mTorr. Gradually the pressure will
again go down to 500 mTorr; the
heaters will turn on and the pressure
will rise to 600 mTorr when the
heaters will again shut off. This cycle
repeats until the food is dry.
