void the vacuum pump warranty. The
door latch is a two-staged handle.
Make sure you turn the handle as far
to the right as possible.
11.
Make sure to close the drain
valve on the freeze dryer (located on
the left side of your freeze dryer). If
the drain valve is not closed, there
will be a vacuum leak which could
damage your vacuum pump, cause an
oil spurt, and void the vacuum pump
warranty.
12.
As described in steps 6-11, it is
your responsibility to make sure
your door is closed properly, that the
drain valve is closed, and that the
hose connecting the vacuum pump
to the freeze dryer is connected
properly. If your freeze dryer doesn't
pull a vacuum, an oil spurt will make
a mess as it may spray a cup (or
more) of oil out of the pump. Again,
it is your responsibility to make sure
that you have a good vacuum seal.

Turn on the freeze dryer (on the
back of your freeze dryer press the
switch to the "up" position). Next,
in order to perform a quick test and
assure that your freeze dryer is set
up properly, please complete the
following steps. To accomplish this
task, your freeze dryer chamber
must be free of any moist material,
water, or condensation. It needs to
be completely dry.

• Press "Start" on the touchscreen.
You will then be reminded to
"Please close drain valve." Ensure
that this valve is closed.

• Initially, you will see "Freezing for
9 hours" appear on the display.
Now, press the small blue clock in
the top right corner of the display.
This will automatically turn your
vacuum pump on (the initial
vacuum will be a bit loud, but will
quickly settle to a hum that isn't
too noticeable.)
• When the vacuum pump first
turns on, the display will read
">2500 mTorr". Within 10-20
minutes the display will no longer
read ">2500 mTorr", but will begin
to show a lower number (starting
with 2500 and moving down). This
number represents the vacuum
pressure inside the freeze dryer.
A lower number represents a
stronger vacuum pressure.
• Eventually, the pressure will go
from 2500 down to 500 mTorr,
and possibly lower. If you see
that this is the case, it means that
your freeze dryer has been set up
properly and you are ready to start
your first batch. If you are unable
to achieve a vacuum of 500 mTorr,
