We have been using a Mr. Slim type ductless AC system from Mitsubishi. The problem is in cleaning the squirrel cage fan that comes with the system. Over a period of time black crud or mold or something accumulates on the blades of the fan, thus reducing the overall efficiency of the system. It's hard to figure out how to remove the squirrel cage fan to clean it. Anyone have any ideas or know where I can get some info. ?? Thanks,
They sure make it hard to reply. First I had to register. When I had just about finished, something about a survey popped up and wiped out this long reply. Now, I hope, to business. Removing the squirrel cage looks like a risky job, but you can get access to it through the bottom opening sufficient for cleaning. First, remove the elevational vane. The left end is on a splined shaft that drives it. At the center and right are hinges that can be disengaged. With the unit off, note the position of the vane, so that you can replace it in that position. Find the left end of each of the other hinges by feel and slide a plastic lug there to the left. Catch the vane when you undo the last hinge, lower it a bit, and move it to the right a bit to disengage the splined shaft. Set it aside. The other barrier is two subassemblies, each running half the width of the slot, each bearing a wire guard and a set of azimuthal vanes with parallel-motion linkage. 2/5 of the way from the proximal end to the distal end of each subassembly is a protrusion sticking toward you, and behind it a square hole. A wedged-shaped projection on the substrate protrudes through the hole to prevent the subassembly from moving away from the wall. Slide a hack-saw blade or other metal strip under the protrusion and over the wedge, so that the subassembly is free to move away from the wall. Then, move the distal end of the subassembly away from the wall. It resists movement, but when you have forced it about 1 centimetre in that direction it is free to drop. By non-forceful manipulation I don't clearly remember, you can then disengage the proximal end. Consider whether you want to reinstall those subassemblies. (I have no need for them, because I need the straight blast, they impede air-flow and they are a nuisance.) To clean the squirrel cage, if it's like mine, you need a toothbrush for the outer edges and a bottle brush ~5 millimetres diameter for the spaces between the blades. (My wife found a suitable makeup brush.) Start by cleaning ~15 centimetres at one end, and then run the unit. If yours is like mine, you will find an enormously satisfying difference in the air flow from where you worked.

"You don't need to register to reply or post new."3 years ago (when he was trying to post) you did have to register.And that was 5 years after the dude asked the question.So it's been 8 years I'm sure he figured it out by now. LOL
