• Comply with max. permitted ambient and gas temperature (see ”Technical
data”) and make sure ventilation is adequate if the equipment is installed in a
housing or if ambient temperature is elevated.
• Avoid high heat supply (e. g. due to hot process gases).
• In case of residues or aggressive or condensable media install a gas washing
bottle if necessary.
When the device is brought from cold environment into a warm room for operation
bedewing may occur. Allow the device to acclimatize.
Comply with national safety regulations and safety requirements concerning the
use of vacuum and electrical equipment. Comply with all applicable and relevant
safety requirements (regulations and guidelines), implement the required ac-
tions and adopt suitable safety measures.
Operating conditions
➨ DVR 3 has only an approval according to device labelling.
Ensure that the materials of the wetted parts are compatible with the substances
processed in the vacuum system, see section “Technical data”.
Safety during operation
➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive,
corrosive, noxious or polluting fluids, vapors and gases.
➨ Prevent any part of the human body from coming in contact with the vacuum.
Max. permitted pressure at the vacuum gauge: 1.1 bar absolute with hose nozzle;
1.5 bar absolute with small flange connection.
• The display flashes at a pressure above 1060 mbar.
☞
Attention: If the pressure is higher than approximately 1060 mbar the pressure
reading becomes incorrect (saturation of the pressure transducer). The display
flashes. Immediate pressure relief necessary! Risk of bursting!
• Use only genuine spare parts and accessories. Otherwise safety and perfor-
mance of the equipment as well as the electromagnetic compatibility of the equip-
ment might be reduced.
Possibly the CE mark becomes void if not using OEM spare parts.
Electronic equipment is never 100% fail-safe. This may lead to an ill-defined sta-
tus of the equipment or of other connected devices. Provide protective measures
against malfunction and failure. Ensure that in case of failure the device and the
vacuum system always will turn into a safe status.
