Every project in our company is covered by warranty care in accordance with the provisions of the general terms of contracts. All elements produced by us are equipped with a relevant maintenance card, which records each interference in a given device. The internal maintenance quality control system allows us to systematically conduct maintenance works and keep their records. Under the warranty as well as during the post-warranty period our products undergo regular technical inspections, maintenance cleaning and electrical measurements. The frequency of the works, the time of response of the maintenance staff and the value of an inspection is determined on the terms stipulated in the terms of contract.
