DANGER
Fire and explosion hazard by exceeding the auto-ignition temperature of the solvent
with a too high gas inlet temperature.
Damage to the vacuum pump. Serious injury or death from burns and / or explosion
pressure.
Do NOT exceed the maximum gas inlet temperature of the pump. Adjust the tempera-
ture set-point accordingly.
With a higher set-point temperature, take appropriate measures to cool down the ex-
tracted vapor before it enters into the vacuum pump.
Extracted vapors can have a health damaging and/or corrosive effect on the chamber and pump.
CAUTION
Health hazard due to release of extracted vapors.
Corrosion of oven and pump. Damage to health.
Conduct the extracted vapors e.g., into a fume extractor facility. Connect a suitable
hose to the vacuum pump outlet that may be located in the pump module.
To avoid condensation inside the chamber and in the suction system, select an appropriate vacuum source
to ensure its sufficient performance in relation to the released amount of steam. Coordinate drying temper-
ature, suction performance of the vacuum source and the amount of loading material.
6.5.2 Vacuum pump VP4 (option)
. The VP4 chemical membrane pump is located in a separate transport packaging. It is delivered as com-
plete pump stand with a separator and an exhaust waste vapor condenser.
We recommend to install the vacuum pump in the optional pump module. For installation of the pump,
please refer to chap. 6.5.3.
