Page 4: Introduction
These optional accessories are described in Section 6.0 and depicted in Appendix B. The ModulyoD may also be used as a low tem- perature vapor trap (cold trap) for a variety of devices. These include vacuum concen- trators, rotary evaporators and vacuum ovens. -

Refer to Figure 3, on page 6 for the location of components of the refrigeration system on the ModulyoD. NOTE: There are no longer user-serviceable parts inside the ModulyoD refrigeration system. The condenser chamber is cooled by refrigerant, which evaporates in the copper cool- ing coil wound externally around the chamber. -

Page 8: User Interface
It is located on the upper sloping surface of the front fascia of the ModulyoD. Through this interface the user will switch on and off and moving refrig- eration and vacuum. Figure 5, Figure 2 and Table 1 (below) locate and describe, in detail, the function of each item. -
Page 9: Front Fascia
PROGRESS BAR 1.2.1.4 FRONT FASCIA The front fascia forms the front of the ModulyoD cabinet. The user interface is located on the upper right-hand portion of this surface. The drain outlet, drain valve and vacuum port are located on the lower left-hand portion. -

1.2.1.6 CONDENSER EXTENSION ASSEMBLY The ModulyoD is shipped with the condenser extension assembly installed (see Figure 8). This extension assembly is necessary to prevent the formation of ice in the vacuum pump connection. The extension assembly should only be removed when working with the Spin... -
Page 11: Protection Devices
Figure 8 — THE CONDENSER EXTENSION TUBE PROTECTION DEVICES The ModulyoD and vacuum pump, if connected to the auxiliary power outlet, are protected by a circuit breaker built in to the mains power switch. You must manually reset the switch whenever the circuit breaker is activated. (Please refer to Section 2.3 for electrical requirements). -
Page 12: The Freezing Process
(see Appendix C) during the freeze drying process. 1.4.4 VAPOR TRAPPING When the ModulyoD is used as a vapor trap (for example, in gel drying applications), its function is significantly different than that when it is used in freeze drying applications. -

Page 14: Construction Details
CONSTRUCTION DETAILS 2.4.1 LEGISLATION AND STANDARDS The ModulyoD has been designed in compliance with the following legislation and standards: • CE Directives 2.4.2 CONSTRUCTION MATERIALS Item Material Cabinet Steel Condenser chamber Stainless steel Vacuum pipeline Stainless steel Condenser extension-tube VACUUM PUMP REQUIREMENTS Note: Your vacuum pump must have a gas-ballast facility to prevent water build up in the pump. -
Page 15: Installation
We recommend leaving an air-gap of at least 200 mm (8 in) between all four sides of the ModulyoD and any wall or obstruction. If you do not leave a sufficient air- gap, poor cooling of the ModulyoD may result in poor performance. When locating the ModulyoD, consider ease of access for maintenance and repair work, which may require removing the cover of the ModulyoD. -
Page 16: Connect The Modulyod To The Electrical Supply
Connect the vacuum pump to the vacuum pump connector on the front of the ModulyoD (Figure 1, item 7). The connector is suitable for use with a 10 mm inside diameter pipeline. -
Page 17: Pump Outlet Safety
CAUTION: Do not attempt to use the ModulyoD if it fails the installation test. If you do, poor performance may result in the loss of the sample being freeze dried. - Page 18 Check the pressure in about 30 minutes. The pressure should be less than 70 microbars. If the ModulyoD has passed through all these steps, it is ready for use. Refer to Section 4 on operation.

SEQUENCE OF OPERATION Operation of the ModulyoD can involve a number of different steps, as shown in Table 4 below: Operation step... -
Page 20: Prepare The Modulyod
The condenser chamber is at a very low temper- ature and can cause tissue damage. Note: If you cool the ModulyoD with no product in the chamber, the chamber temper- ature will cycle between approximately -40 ˚C and -55 ˚C. -
Page 21: Drying
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]). -
Page 22: Shut Down
• If there appears to be a leak, check that the drain valve is fully closed and all seals are clean. If the ModulyoD continues to leak, contact your Thermo Electron distributor. SHUT DOWN... -
Page 23: Defrost The Modulyod
Alternatively, you can pour warm water into the ice condenser to speed up the defrost- ing process. This method is useful if you wish to use the ModulyoD again, immediate- Use the following procedure: Remove the drying accessory from the accessory flange. -
Page 24: Operation With No Load
ModulyoD get very cold. Atmospheric water vapor will then condense onto the cold surfaces and may drip out of the bottom of the ModulyoD. You may, therefore, see pud- dles of water under the ModulyoD, which give the impression that water is leaking from the condenser chamber. -
Page 25: Refrigerant Leaks
REFRIGERANT LEAKS The refrigerant used in the ModulyoD is heavier than air and is an asphyxiant by the displacement of oxygen. If a refrigerant leak is suspected, place the unit in a well-ven- tilated area. Do not allow naked flames or smoking near the ModulyoD, as products of combustion of the refrigerant include dangerous fluorides and chlorides. -
Page 26: Warranty And Liability
The rubber gasket surrounding the flange on the pipeline adapter forms the vacuum seal with the accessory flange on the top of the ModulyoD. Once in position, vacuum tubing from the desired device is connected to the pipeline adapter and secured with a hose clamp. The vacuum hose connecting the ModulyoD to the vacuum source is connected in the manner described in Section 3.4. - Page 30 Thermo Electron Corporation Bioscience Technologies 450 Fortune Boulevard Milford, MA 01757 866.9.THERMO (866.984.3766) Fax: 508.634.2199 www.thermo.com Laboratory Pipetting and Consumables Molecular Biology info.pipettes@thermo.com info.molbio@thermo.com Microplate Instrumentation Sample Preparation info.microplateinstruments@thermo.com info.sampleprep@thermo.com Laboratory Automation & Integration New Labs info.labautomation@thermo.com newlabs@thermo.com Controlled Environment Services info.controlenv@thermo.com services.biosciencetech@thermo.com...
