Following the sequence of videos, here is video 2, where I remove the Maneurop compressor sieves and the thermostatic expansion valve sieves to check the dirt situation. In this case, the sieves were very dirty, which causes a lot of damage to the refrigeration system, such as loss of system efficiency. All these videos and others are on my YouTube channel Rafael Ferreira Refrigeração. Thank you very much in advance to everyone for all the support and affection, you are amazing.
