If operating the ModulyoD with no load for several hours, the internal components of
the 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.
If you see water dripping out of the ModulyoD, inspect the condenser chamber. If there
is ice in the chamber, the water is probably not leaking from the chamber, but is drip-
ping from the cold surfaces inside the ModulyoD. Always check this carefully before
contacting your supplier.
To avoid this problem, we recommend shutting down the ModulyoD if not using it for
more than three or four hours. This is particularly important if you use the unit in a high
humidity environment.
4.9 OPERATION WITH NO LOAD
Note: You must follow the maintenance procedures defined in the instruction manuals
supplied with your accessories and vacuum pump.
The following sections describe possible problems and their possible solutions, and are
intended as a guide to the user and to qualified service engineers. Some of the solu-
tions may be carried out by the user, but others (which are clearly identified) must be
carried out only by approved Thermo
Electron
service engineers.
5.0 MAINTENANCE
WARNING: Obey the safety instruction given below and take note of appropriate
precautions. If you do not, you may cause injury and damage to equipment.
5.1 SAFETY
• Switch off the ModulyoD, isolate it from the electrical supply, and defrost
it before starting maintenance.
• Do not touch any part of the condenser chamber during or immediately
after the cooling process. The condenser chamber is at a very low tem-
perature and may cause tissue damage.
• Do not pour water at a temperature greater than 50 ˚C into the condenser
chamber when it is cold. If you do, this may result in a dangerous pres-
sure rise in the refrigeration system.
• Ensure that any fault finding is done in a well-ventilated area.
• After you have rectified a fault, ensure that the electrical installation of
the ModulyoD conforms with your local and national safety requirements.
It must be connected to a suitably fused and protected electrical supply
and a suitable earth (ground) point.
