DK32 - DK34 - DK37INSTALLATION 33.1 Notes on installationINFORMATION!Inspect the cartons carefully for damage or signs of rough handling. Report damage to thecarrier and to the local office of the manufacturer.INFORMATION!Check the packing list to check if you received completely all that you ordered.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 requirementsCAUTION!When installing the flowmeter in the piping please observe the following points:• The variable area flowmeter must be installed vertically (measuring principle). The flowdirection must be from bottom to top. For installation recommendations please refer also toVDI/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 theflowmeter.• 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 isrequired (see Technical Data).07/2009 - 4000287102 MA DK32-34-37-R04-enwww.krohne.com13
