1301	Low Pressure Fault.Low Pressure sensor (63LS) reads below 1 Bar in the system.	Possible refrigerant leak. Restriction or blockage in refrigerant circuit causing low side pressure to drop. Problem with pressure sensor reading incorrectly.	Check the system standing pressure for a complete gas loss.Use the Testing dip switches in the app and compare system gauge pressure to Low Pressure Sensor reading – If the pressure sensor is faulty it will read 0.0 bar even though there is pressure in the system.	Using the testing dip switches check the system running pressures/temperatures to determine if the system is short of gas or if there is a restriction/blockage in the circuit.For refrigerant circuit diagram click the link below and type unit model number into the document library search box
