WARNING
Release of extracted vapors.
Danger of injury.
Damage to oven and pump by corrosion.

Remove the extracted vapors and, if appropriate, the inert gas from the module via a
suitable conduit into e.g., a fume extractor facility.
 Directly connect the conduit to the corresponding pump outlets.
You can connect a laboratory cooling system to the emission condenser of the vacuum pumps
VP4 or VP5.
To operate the chemical membrane pumps VP4 (MZ2C EX) or VP5 (MD4C EX), please
refer to the enclosed pump manufacturer's operating manual.
Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the
used drying temperature, or take appropriate measures to cool down the extracted vapor be-
fore its entry into the vacuum source.
The ATEX (Directive 94/9/EG) compliant vacuum pumps offered by BINDER are designed for a gas
inlet temperature of 40 °C / 104°F max. Do NOT exceed this temperature. If the gas inlet temperature is
too high and then becomes even warmer by compression in the pump, the resulting temperature (of the
gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and ignition tempera-
ture.
DANGER
Exceeding the gas inlet temperature.
Exceeding the ignition temperature of the solvent.
Risk of ignition and explosion.
Damage to the vacuum pump.
Danger of death.
∅
Do NOT exceed a set-point temperature of 40 °C / 104°F.
 With set-point temperature > 40 °C / 104°F, take appropriate measures to cool down
the extracted vapor before its entry into the vacuum pump.
The maximum permissible ambient temperature of the vacuum pumps delivered by BINDER is 40 °C /
104°F.
15.4 Additional measuring channel for digital object temperature display with
flexible Pt 100 temperature sensor (option)
The object temperature display permits recording the object temperature directly on or in the drying mate-
rial. The object temperature is measured via a flexible Pt100 sensor inside the inner chamber. The sensor
needs to be in thermally conducting contact with the charging material. It can be plunged into humid
charging material up to the length of its protecting tube.
