Safety information!
General information
☞ Read and comply with this manual before installing or operating the equip-
ment.
☞ Do not use the equipment if it is damaged.
Remove all packing material, remove the product from its packing-box, remove the
protective covers and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
Intended use
☞ The device is designed for ambient and gas temperatures at the pressure trans-
ducer connection of +10°C to +40°C at continuous operation, up to +80°C for
short periods (< 5 minutes) at the pressure transducer. If installing the device into
a cabinet or a housing check maximum temperature. Ensure that the maximum
permitted gas temperature at the pressure transducer (see ”Technical data”) is
not exceeded.
Use the equipment and all system parts for the intended use only, i.e. for measure-
ment of vacuum in vessels designed for that purpose.
Connecting the device
☞ Avoid uncontrolled overpressure (e. g. when connecting to a locked or blocked
tubing system). Risk of bursting.
☞ 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.
☞ Power supply by an internal 9V battery.
Do not charge the battery. Do not open the battery. Do not throw the battery into
fire. Do not heat over 100°C and do not bring in contact with water.
• Comply with maximum permissible pressures at the pressure transducer. See
section ”Technical data”.
• Connect hoses gas tight at the pressure transducer connection.
• Ensure the stability of hose connections.
• In case of residues or aggressive or condensable media install a gas washing
bottle if necessary.
Avoid high heat supply (e.g., due to hot process gases).
Connect the vacuum gauge to the vacuum application.
Position the vacuum gauge and its vacuum line in such a way that condensate can-
not flow towards the internal pressure transducer.
