Prepare The Modulyod; Fit The Sample Container And Other Accessories; Pre-Cool The Modulyod - Thermo Scientific ModulyoD Instruction Manual

4.3 PREPARE THE M
Note: Use only mild detergents to clean the condenser chamber, accessories and con-
necting pipeline. Some of the Thermo Electron accessories are made from acrylic mate-
rials and must not be cleaned with organic solvents.
Before you first use the ModulyoD, and between freeze drying cycles, prepare the
ModulyoD, as follows (refer to Figure 1):

The accessory sealing-ring should not need lubricating.

FIT THE SAMPLE CONTAINER AND OTHER ACCESSORIES

A drying accessory may be connected to the ModulyoD accessory flange. Accessories
have a rubber sealing-ring to seal the accessory to the ModulyoD accessory flange.
Once positioned, the weight of the accessory is sufficient to produce an air-tight seal
under vacuum conditions.
4.5 PRE-COOL THE M
WARNING: Do not touch any part of the condenser chamber during or immedi-
ately after the cooling process. 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.

Turn the drain valve fully counterclockwise to open the valve and to
remove any water left in the bottom of the condenser chamber. When the
chamber is completely drained, turn the drain valve fully clockwise to
close it.
If acidic or corrosive products have been processed, flush through the
condenser chamber and drain outlet with clean water.
Make sure that the condenser chamber is dry.
Make sure the ModulyoD is clean, particularly the accessory flange. If the
flange is not clean, you will not get a good vacuum seal and the perfor-
mance of the ModulyoD will be poor.
Confirm that both the vacuum pump and the ModulyoD are properly con-
nected to the interconnecting vacuum tubing.
Select a suitable drying accessory for the product. Wipe clean the seal-
ing-ring of the accessory and check the sealing-ring for damage; if it is
damaged, fit a new sealing-ring.
