I have this equipment, it cools an enormity, but it makes a noise, I ask and they tell me that the fan bushings are dry, that it would be good to lubricate them. It was winter and I did not give it much importance, now I want to fix it, as the known technician is not available, choose to put a hand, take out the front, the filter a real disgust, covered in dirt, wash it with warm water and dry, move the team out, but as I don't know if I can stand it, I'm almost 70, so with a W40 I sprayed the shaft, the noise dropped a lot, but I would like to lower it completely and see the bushings, I thought I would have wheel bearings, the idea is that they tell me if they have bushings or bearings, and the weight of the equipment With the very dirty filter the same cooled, now we have to cover, we have 3 more air at home, 2 split between them, and they do not reach the heels despite being almost new. From already very grateful. [B] [/b].
