Safety information!
Remove all packing materials, remove the equipment from its packing-box, remove
the protective covers and 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 equipment together with the order number and the
suppliers´ invoice number. Retain all packing materials for inspection.
Do not use the equipment if it is damaged.
☞
Read this manual before installing or operating the equipment.
Obey
national safety regulations and safety requirements
concerning the use of
vacuum and electrical equipment.
☞
Product must be connected only to a suitably fused and protected electrical supply
and a suitable earth point. Failure to connect the device to ground may result in
deadly electrical shock.
☞
Check that mains voltage and current conform with the product (see rating plate).
☞
Ensure that installation is in compliance with limitations from the degree of protec-
tion, see “Technical data“.
☞
The product is equipped with a short circuit proof transformer with an integrated
overload protection (no fuses).
Operate the equipment only in combination with VACUUBRAND genuine accessories.
Obey
all other relevant safety requirements
(e. g. accident prevention regulations for
working in laboratories and explosion protection guidelines) and provide
protective
measures
.
Max. ambient temperature:
40°C
☞
Make sure ventilation is adequate if product is installed in an enclosure or if ambi-
ent temperature is elevated.
The devices are
not suitable
when working with
dangerous or explosive gases or
explosive or flammable mixtures
. Ensure that the materials of the wetted parts are
compatible (see “Technical data“). If necessary adopt suitable measures.
☞
Temperature of the Pirani sensor is about 170°C.
☞
If residues can occur or if aggressive or condensable substances may enter the
product, install suitable protection (e. g. gas washing bottle).
☞
Position the product in the vacuum system so as to avoid flow of condensate
towards the gauge head.
DVR 5:
Max. permitted pressure:
1.5 bar (absolute).
☞
At a pressure greater than 1060 mbar the digital pressure
display and the warning
triangle are flashing
.
Attention:
At a pressure greater than 1100 mbar the pressure measurement is incor-
rect (saturation limit of the pressure transducer).
VAP 5:
Max. permitted pressure:
1.5 bar (absolute).
Exclude sudden pressure changes when gauge head is operated.
☞
Pirani filament can be destroyed.
Ensure that the gauge head is electroconductively connected to an earthing wire when
the Pirani sensor is exposed to charged particles (ion-beam, plasma).
☞
Use only electroconductive centring/clamping rings. Do not connect the gauge head
via a nonconductive hose.
