My friend gave this portable air conditioner and it is missing the small plastic water tray at bottom right and i dont have an owners manual to it and it isnt cooling like its supposed to and could somebody please get back to me and let me know where i could locate one of the plastic water trays that sit inside the unit acting either as a collection tray or as a runoff tray or maybe its serving another function. if somebody knows something that could help me in my dilemma please send me an email because i sure could use some help. Thank you so much and have a nice day. William Yakel
