• Check the direction of rotation of the fans (indicated by an arrow on the fan's own volutes).
• Check that the electrical current of the evaporator motor is not greater than the rated value.
• Check the evaporator flow or fan speed values are within the specified in the installation project.
• If the compressor presents a high noise and there is no pressure differential between discharge and suction, check the sequence of the power supply phases.
• Check that the siphons and drains are working properly.
• Make sure that there is no leakage in the refrigerant circuit.
• Adjust the gas load if necessary, according to the manufacturer's guidelines.
