DK32 - DK34 - DK37 INSTALLATION 3 3.1 Notes on installation INFORMATION! Inspect the cartons carefully for damages or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer. INFORMATION! Do a check of the packing list to make sure that you have all the elements given in the order. INFORMATION! Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate. 3.2 Storage • Store the flowmeter in a dry and dust-free location. • Avoid lasting direct exposure to the sun. • Store the flowmeter in its original packaging. • The permissible storage temperature is from -40 to +80°C for standard meters. 3.3 Installation requirements CAUTION! When installing the flowmeter in the piping please observe the following points: • The variable area flowmeter must be installed vertically (measuring principle). The flow direction must be from bottom to top. For installation recommendations please refer also to VDI/VDE Directive 3513 Sheet 3. • Before connecting, blow or flush out the pipes leading to the flowmeter. • Pipes for gas flow need to be dried before the flowmeter is installed. • Use connectors suitable for the particular version of the flowmeter. • Align the pipes axially with the connections on the flowmeter so that they are free of stresses. • If necessary, the piping has to be supported to prevent vibrations being transmitted to the flowmeter. • Do not lay signal cables directly next to cables for the power supply. • If several instruments are installed side by side, a minimum distance between these divices is required (see Technical Data). 01/2012 - 4000287103 MA DK32-34-37-R05-en www.krohne.com 13
