  • Page 4: General

    General Information These instructions provide important notes on using the leak detector DLR-G. Complying with all safety instructions and guidelines is a pre- requisite 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.

  • Page 5: Warranty Conditions

    General Warranty Conditions We provide warranty for the leak detector DLR-G 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.

  • Page 6: Safety

     Section 3.4.5 must be complied with. Any claims arising from misuse are excluded. Obligation of the Operating Company The leak detector DLR-G is used in a commercial environment. The operating company is therefore subject to statutory occupational safe- ty obligations.

  • Page 7: Qualification

    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 humans National guidelines must be adhered to.
