The meter left the factory in a faultless condition where safety is concerned. The manufacturer will provide additional technical support on request. Calibration relevant security seal on the meter must not be damaged or removed. Otherwise the guarantee and calibration validity of the meter will lapse.
 Keep the packaging so that you can transport the meter in its original packaging following expiry of the calibration validity.
 Lay all cables at a minimum distance of 500 mm to high voltage and high frequency cables.
 A relative humidity of <93 % at 25 °C is permissible (without condensation).  Avoid cavitation in the whole system due to overpressure i.e. at least 1 bar at qp and approx. 3 bar at qs (applies for approx. 80 °C).  At a heating meter the mounting place of the flow sensor cold side is equivalent to return. The mounting place of the flow sensor hot side is equivalent to flow.  At a cooling meter the mounting place of the flow sensor hot side is equivalent to the return. The mounting place of the flow sensor cold side is equivalent to flow
