Acson Ceiling Exposed is uniquely designed with the option to install either below the ceiling or mounted on the floor to suit any interior design requirement. Ceiling and Floor Installation Option The ACM-E and ACM-D series are uniquely designed with the option to install either below the ceiling or mounted at low wall position to suit any interior design requirement. Flexible Installation The ACM-E model is designed to work with high pressure head drain pump (optional). Thus offering flexibility for installation on condensate drain pipe. The drain pump comes with a high head and is incorporated with the float switch as safety protection. Better Serviceability The new ACM-E series allows the washable filter to be easily access by just pulling down the intake grill. During servicing or repairing, only the bottom panel need to be removed in order to access. Fresh Air Option The ACM-E series is designed to draw in fresh air from outdoor. A fresh air knock out hole is designed within the unit itself to provide better ventilation. - See more at: http://www.priceinpkr.com/item/acson-1-0-ton-air-conditioner-acm15e-alc15c-price-in-pakistan/#sthash.EysIScSj.dpuf
