5.2. Preparations
Check that the CoolSafe ice condenser is free from ice and water, and that all valves i.e. the drain valve is
closed.. Check that there is no water in the drain valve.
Check that the gas ballast valve on the vacuum pump is open at all times. Check the oil level in the
pump and the oil mist filter. The filter must be operated with maximum 10-mm oil level (preferably
empty).
Switch on the CoolSafe and the vacuum pump. The CoolSafe will enter the WAIT-STATE indicated
by a flashing yellow LED, and the cooling process starts. Just after switch on, the display shows the
actual software version and then all display segments are switched on for a test the of display. After
a few seconds, the temperature measurement is stabilized and the actual condenser temperature will
be displayed.
The vacuum pump should now be allowed to run for at least 30 minutes before opening the
(external) vacuum valve. This period of time also allows the condenser to reach operational
temperatures (below -90 ºC or -55C) indicated by the GREEN LED, which signals that the
CoolSafe is ready and OK for freeze-drying to commence..
The product has to be in frozen state using auxiliary equipment, i.e. freezer, liquid nitrogen etc or use
the condenser as a freezer. To avoid product melting within the time it takes to move the product to
the freeze dryer and establish a pressure below the triple point, the temperature of the product should
be brought down to as low a temperature as possible.
5.3. Freeze-drying using manifolds
1. Check that all rubber valves are closed (A) or in vacuum-release position (C), and that the flange and
lid are tight.
