Pre-cool the ModulyoD condenser chamber as follows:
1. Ensure that the displays on the control panel (item 3, Figure 1) are
illuminated (that is, that the ModulyoD is connected to the electrical
supply and the main switch [item 4, Figure 2] is on).
2. Press the 'Fridge' button. (item 1, Figure 5).
3. Leave the ModulyoD on until the temperature shown on the temperature
display (item 3, Figure 5) is -45 °C or lower.
4. Wait an additional 10 minutes before operating.

WARNING: Never engage the vacuum pump when water is present in the Ice
Condenser. The introduction of water directly into the internal mechanism of the
vacuum pump will cause significant damage to the pump.
CAUTION: Use the gas-ballast on the vacuum pump when drying. If you do
not, water may condense in the pump.
1. On Thermo Electron high vacuum pumps, install the GBORK gas ballast
oil return kit, referring to its instructions. On other pumps, fully open the
gas-ballast valve (refer to the pump instruction manual).
2. Activate the pump “ON” by pressing 'Pump' button (item 5, Figure 5) if
the pump is electrically connected to the ModulyoD vacuum pump
power outlet (item 2, Figure 2).
Take note of the following when freeze drying products:
• Switch on a heated accessory only when the pressure is 1 mbar or less.
(Green light on the vacuum progress bar is illuminated [(item 8,
Figure 5]).
• When a load is first applied to the ModulyoD, the temperature may rise
for a few minutes. This is due to the high initial evaporation rate from the
sample. If the temperature does not fall to ~-45 ˚C or below within a
few minutes, the ModulyoD is overloaded. Reduce the amount of
sample in the freeze drying system to prevent the sample from melting.
When using the ModulyoD as a vapor trap, restrict the flow of vapor to
the ModulyoD (for example, by using the pipeline attachment accessory
[Appendix B, item 12]).
• If you wish to dry a number of flasks, first attach one flask, then evacu-
ate the flask until the pressure (green light on the vacuum progress bar
[item 8, Figure 5] is on) falls to 1mbar or less. Then attach and evacuate
the remaining flasks in the same way.
