Operator’s Manual for the Quietek

Preparing the Quietek for Use
• Insert the power supply (round) plug
into the receptacle OR power jack on
the back of the Quietek controller, and
plug the power supply into a standard
outlet.
• Connect the delivery hose to its fitting
on the controller, and attach the other
end to the barbed fitting on the cage lid.
The Quietek 2 has enough fittings to
operate with up to two cages.
Ensure that the lid is large enough so
that bent edges fit entirely around the
rim of the cage. If any part of the bent
metal edge of the lid is in contact with
the cage rim, the lid may not seat
properly.
Adjusting the Settings
Before you begin: Determine the
volume of your cage, in liters. A cage
volume calculator is available at
cagevol.nextadvance.com.
• Select the setting that you wish to
adjust (A or B) using the “Cage Size”
switch. The Quietek can store two
different cage volume/flow rate
combinations.
• Turn the key to the "Adjust" position.
• Set the cage volume using the “Cage
Vol.” knob. Measurements are shown
in liters.
• Set the desired fill rate using the “Fill
Rate” knob. Flow rate is controllable
within the range specified in the
AVMA guidelines. If you have a
Quietek XL model, you will not be able
to use very low flow rates at small cage
sizes (below 60L).
• Turn the key to the "Run Mode"
position. If the key is removed in run
mode, the machine will still run and the
settings will not be adjustable.
Note: For the Quietek 2, settings A or
B depending on the orientation of the
“Cage Size” switch) will apply to every
cage or chamber that is connected to the
device.
Performing a Run
• For every cage or chamber being
used, confirm that the lid is properly
fitted, with the lining in full contact
with the cage rim.
• Open the valve on the CO
2
source.
• Ensure that the key lock is in the "Run
Mode" position. Run will not start if
the key is in the "Adjust" position.
• Press the "Start/Stop" button. If you
are using the Quietek 2, press the
“Start/Stop” button that corresponds to
the cage(s) you want to use. The "CO
2
fill" light corresponding to the cage you
are using will illuminate, and the timer
will count down until one cage volume
of gas has been delivered.
• When the cage is filled, the CO
2
flow
will stop. The "Immersion" light will
illuminate and the timer will show time
elapsed since immersion began.
• To stop the run, press "Start/Stop"
again. The controller will reset, and
