3.2 FREEZE DRYER ASSEMBLY
1.
Wait 24 hours before running
your freeze dryer in order to
facilitate proper settling within the
refrigerator condensing unit. Waiting
24 hours will allow the oil in the
condensing unit to settle so that the
freeze dryer can get cold enough.
2. The ideal location for operating
your freeze dryer is a cool, dry, clean
location. Operating your freeze dryer
in temperatures higher than 75
degrees Fahrenheit may cause cycle
times to take longer.
3. Place the freeze dryer on a level,
stable surface and adjust the leveling
feet so that the front end of the
freeze dryer is about ¼ to ½ inch
taller than the rear. This allows
the water that accumulates in the
chamber of the freeze dryer to exit
through the drain hole in the rear
of the vacuum chamber. Make sure
the translucent (clear) drain line is
placed in a 5-gallon bucket, a drain,
or an equivalent container to catch
the water. Make sure the drain valve
is tilted slightly down and not at on
the table or cart.
4. Connect the freeze dryer power
cord to the receptacle on the rear
panel and to a 110 to 120 volt ac
power supply (power may vary
between models).
5. Connect the power cord on the
vacuum pump to the receptacle on
the rear panel of the freeze dryer.
6. Make sure the power switch on
the vacuum pump is in the “on”
position. The power button is
located on the rear of the vacuum
pump. The control circuit in the
freeze dryer will control when to
turn “on” and “off” the vacuum pump.
7. Connect the large clear hose to the
freeze dryer (see Figure 6) and to the
vacuum pump (see image on page 4,
Figure 1, A) and tighten hand tight.
8. Make sure all other caps and ports
on the vacuum pump are closed
tightly (hand tightened only).
9. 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.
