Inappropriate execution of the pump connection can lead to the risk of explosion.
DANGER
Inappropriate pump connection.
Risk of ignition and explosion.
Danger of death.

It is important to observe the pump manufacturer’s instructions regarding correct con-
nection and commissioning.
 Observe the safety advice of chap. 1.5.
Extracted vapors or the occasionally used inert gas can endanger health and/or have a corrosive effect on
the oven and pump.
WARNING
Release of extracted vapors.
Danger of injury.
Damage to the 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.
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.
A gas inlet temperature of 40 °C / 104°F maximum must NOT be exceeded. If the gas inlet tempera-
ture 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
temperature.
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 in the vacuum pump.
