General Information These instructions provide important notes on using the leak detector DLR-GS. Complying with all safety instructions and guidelines is a prerequisite for safe working. Furthermore, any local regulations for prevention of accidents appli- cable at the site of use of the leak detector and general safety instruc- tions must be complied with.
General Warranty Conditions We provide warranty for the leak detector DLR-GS for a period of 24 months from the day of installation on site in accordance with the General Terms & Conditions. The maximum warranty period is 27 months from our date of sale.
Section 3.4.5 must be complied with. Any claims arising from misuse are excluded. Obligation of the Operating Company The leak detector DLR-GS is used in a commercial environment. The operating company is therefore subject to statutory occupational safety obligations.
Qualification The personnel must be capable of independently recognizing and avoiding potential risks based on their qualifications. Companies commissioning leak detectors should have completed re- spective training with SGB, through SGB or its authorized representa- WARNING! tive. Danger to hu- National guidelines must be adhered to.
Before entering, the corresponding protective measures must be taken and it must be ensured that no gas and sufficient oxygen are present. Other manufacturers' or countries' regulations may provide different percentages PRESSURE LEAK DETECTOR DLR-GS .. - 9 - 06/08/2020...

Design and Function The pressure leak detector DLR-GS monitors both walls of the dou- ble-walled system for leaks. The monitoring pressure during operation is higher than any pressure on the inner or outer wall, so that leaks will be indicated by a pressure drop.
Press and hold the "Mute" button (about 10 seconds). The alarm will be triggered until the button is released. This inquiry is only possible if the pressure in the system has ex- ceeded the "Alarm OFF" pressure. PRESSURE LEAK DETECTOR DLR-GS .. - 17 - 06/08/2020...
