technicians recommend replacing the liquid line filter drier whenever the refrigerant circuit is opened to prevent moisture and contaminants from damaging the new HVAC compressor

preventing the gas valve from opening if the venting system or inducer motor fails to meet required pressure thresholds

ensuring consistent superheat control and preventing compressor floodback during low-evaporator temperature operations

allowing for a seamless drop-in fit without re-engineering the mounting bracket

Siemens Building Technology 7MF15654CD005EA1 Sensor L99H008 technicians recommend replacing the liquidThe Siemens SITRANS P200 7MF1565 4CD00 5EA1 is a high performance liquid pressure sensor designed for demanding HVACR and industrial hydraulic applications. This 0 300 PSIG pressure transmitter features a piezoresistive ceramic measuring cell with a thin film strain gauge, ensuring exceptional long term stability and high overload resistance. Engineered for gauge pressure measurement, it converts mechanical pressure into a precise 4 20mA output
