vacuum pump and the holes in the
white cap point upward. Tighten
snuggly so that the white cap faces
upward. Suggestion: Place a small
sock or cloth over the white cap. This
will help control possible oil misting
and oil spurts.

Pull off the rubber gasket that
comes into contact with the acrylic
door and clean with water inside
and out. Assure that there are no
particulates inside the gasket. If the
gasket is not clean inside and out,
the freeze dryer may have a hard
time pulling a low vacuum. They are
generally clean. Just look to make
sure. Do not stretch the gasket
apart too far while trying to clean
the inside. Stretching too far could
damage the gasket creating a crack
that prevents achieving a proper seal.
11.
Ensure that the acrylic door has
a tight fit against the rubber gasket
by examining the door in the fully
closed position. Check to make sure
there are no small gaps or spaces
between the acrylic door and the
rubber seal. You will see a thin line
around the entire gasket as it presses
up against the door. If there is a gap
at any portion of the seal between
the door and rubber gasket, call

You are now ready to load freeze
drying material onto trays. It is
best to freeze dry materials that are
somewhat similar in moisture content.

Place the trays that have the
material on them in the shelving
unit. Make sure the trays are fully
supported by the heated shelf with no
part of the tray extending out of the
shelving unit. The trays are heated by
the shelving unit and must fit well in
order to receive the appropriate heat
to drive off the moisture.
14.
Place the black insulator door
pad in the opening of the vacuum
chamber (within the opening of the
black rubber gasket). This insulates
the acrylic door from the extreme
cold in the chamber and prevents the
cold from forming ice on the door.
15.
Close the acrylic door and turn
the door latch clockwise as far as it
will go. This will compress the door
closed against the rubber gasket.
Visually check the seal to make sure
the door is sealed properly to the
gasket. If the door is not latched tight,
there will be a vacuum leak which
might damage your vacuum pump
and void the vacuum pump warranty.
16.
Close the drain valve. In the
closed position, the drain valve is
perpendicular to the hose.
17.
Power on your unit (press the
switch on the back of your freeze
dryer to the up position). Now, press
the "Start" button. You will then
be reminded to "Please close drain
valve..." Once you have done this, the
word "Freezing..." will be displayed
on the touch screen.
