remains closed until you enter the freeze drying modes (either opened via the touch screen
in manual mode or via programme sequence in automatic mode).
8.1
Freeze drying
The CoolSafe Touch will allow freeze drying in 10 steps without any further manipulations.
However, if manual mode is used, then all values and time transitions for the freeze drying must be
input manually via the touch screen.
Enter the values for freeze drying, time, shelf temperature and maximum pressure, in 10
steps. If you do not need all 10 steps enter 0.00 for time BUT keep the temperature values
the same. All 10 steps must have values entered.
Pressure regulation (optional) allows programming and regulation of the vacuum to set
values in each of the 10 freeze drying steps. Entering a zero value for pressure, no
regulation is applied. This can be used in the secondary drying phase of the cycle or if no
regulation is required. Possible in the last 4-5 steps of the freeze drying sequence.
8.2
De-ice
The CoolSafe freeze dryers are equipped with electric de-icing. This facility gently warms the wall of
the condenser and facilitates the release and easy removal of the “ice-plug” in the ice condenser.
Caution
Always wear cryo-protective gloves when carrying out this procedure.
If the electric de-icing option is not fitted:
1.
Ensure the CoolSafe is switched off and the vacuum has been released.
2.
Leave the condenser open to the atmosphere, introduce warm water into the condenser
until it is released from the walls of the condenser.
3.
Then remove the ice.
