Installation requirements
1. Pay attention to the direction of the arrow mark on the flowmeter to make the water flow direction consistent with the arrow direction
2. Do not block the valve port with hemp, raw material tape and other debris during installation
3. Handle with care during the installation process and strictly prohibit brutal operation to prevent man-made damage
4. The HVAC pipeline should be cleaned before installation, and the front end of the flow meter should be equipped with a dirt filter and a shut-off valve to remove dirt and repair and replace
5. There should be a straight pipe section not less than 10 times the nominal diameter at the front end of the heat meter, and a straight pipe section distance not less than 8 times the nominal diameter at the back end.
6. The temperature sensor with the red label is installed on the high temperature pipeline, and the temperature sensor with the blue label is installed on the low temperature pipeline. The lead wire of the temperature sensor shall not be increased or decreased at will
7. All parts of the heat meter (including heat meter parts, temperature sensor parts and calculator parts) should be installed in a position to avoid exposure, water flooding, freezing and electromagnetic pollution, and be easy to disassemble
