Dear customer,
Your VACUUBRAND vacuum gauge shall support you at your work for a long time without any trouble and with full load output.Thanks to our large practical experience we attained much information how you could add to an efficient application and to personal safety. Please read these instructions for use prior to the initial start-up of your controller.
VACUUBRAND vacuum gauges are the result of many years of experience in construction and practical operation of these vacuum gauges combined with the latest results in material and manufacturing technology.
Our quality maxim is the ”zero fault principle”:
Every delivered vacuum gauge is tested extensively including an endurance run. Due to this endurance run, also faults, which occur rarely, are reported an can be corrected. Every single vacuum gauge is tested on achievement of the specification after the endurance run.
Every VACUUBRAND controller leaving our factory achieves the specification.We feel obliged to this high quality standard.
We are aware that the controller should not draw a part of the real work and we hope to contribute with our products to an effective and troublefree realisation of your work.
Yours
VACUUBRAND GMBH + CO KG
After sales service: Contact your local dealer or call +49 9342 808-193.

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 protection, 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 ambient 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 incorrect (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.

Ensure that maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures which relate to the equipment processed by the vacuum system and that the equipment if necessary is approximately decontaminated before starting maintenance.
Use only genuine spare parts and accessories.
Otherwise safety and performance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced.
Return of the equipment to the factory for repair, the manufacturer accepts warranty only if housing has not been opened.
Repair of the gauge head VSP 5 and VSK 5 is not possible.
In order to comply with law (occupational, health and safety regulations and regulations for environmental protection) products returned to the manufacturer can be repaired / DKD calibrated only when following certain procedures (see section ”Notes on return to the factory”).
