The Clear Stoppering Chamber is now installed and must be tested
to make certain the system is free of leaks. To test, turn on the
Freeze Dry System refrigeration and allow the temperature to
reach –40° or lower. Make sure the Vacuum Release control is in
the “CLOSED” position. Start the vacuum pump and monitor the
vacuum gauge. The vacuum on the Freeze Dry System should
reach 0.133 mBar within 30 minutes and should achieve an
ultimate vacuum of 0.040 mBar or lower within 18 hours.
If 0.040 mBar cannot be achieved, consult the troubleshooting
section of this manual and of the manual supplied with the Freeze
Dry System.
Venting the Vacuum Pump
If any materials will be placed in the Clear
Stoppering Chamber that can liberate hazardous
gases when heated, the vacuum pump exhaust
must be vented to a fume hood or other
ventilation device.
Electrical Connection
Plug the power cord into the receptacle on the back
of the Clear Stoppering Chamber and plug the other
end into a suitable power receptacle.
DO NOT ATTEMPT TO PLUG THE CLEAR
STOPPERING CHAMBER INTO THE
FREEZONE FREEZE DRY SYSTEM.
