I have a Ypsilon 1.1 of the old

Someone has the explodes or manual of this Ypsilon model the elephantine because when little the air (non -conditioning that does not have) smells burned both in the cold and in the heat and I do not know if it can be the filter that has the ducts and it is to see how I can take it out and put a new one .. and I do not know where it is

thanks
