Description

From the listing uploaded by “appupdater”.

Every year, Installatörsföretagen publishes Teknikhandboken VVS, a handbook for plumbers who on approximately 600 pages shows professional execution of plumbing installations. The purpose of the manual and the app has been to make a book with useful information available in both digital and printed form intended for plumbing installers, fitters and consultants. The handbook mainly deals with heating and water and sewerage installations as well as the water-borne circuits in cooling installations. However, the manual does not deal with ventilation installations, compressed air, control or monitoring installations. The handbook is limited to dealing with ordinary installations, as they usually occur in homes and school and office buildings. The app and the manual contain information about: Dimensions and assembly • Systems and Installations • Labeling • Plumbing • Pipelines • Insulation of pipelines • Goods • Tap water installations • Drainage installations • Heating and Cooling installations • Waste management • Construction material • Chemical products • Water • Drinking water • Drawings and descriptions • Control and adjustment • General technical basics • Standards and guidelines • Safe Water Installation - Industry Rules • Glossary
