White Coleman Mach 3 Plus 13500 BTU Air Conditioner Upper Unit - As one of the best-selling RV air conditioners in the world, the Mach 3 PLUS is also one of the best values. It features a large evaporator and condenser coils with raised lance fins to help dissipate heat, while the all-copper tubing and gas-flux brazed joints ensure durability and long life for your RV air conditioner. The Mach 3 PLUS installs into a standard 14 inch roof vent opening (many RV's have a vent that has wiring near it, making installation easier) and it has a solid 13,500 nominal BTU cooling capacity and delivers 320 CFM (cubic feet per minute) or 543.7 CMH (cubic meters per hour) of airflow. This is the top exterior portion only - interior piece must be purchased seperately. You can also add an optional heat strip for 5600 BTU of heat to take the chill off of those cool mornings (not included). Comes with a 2 speed fan and runs on 115 Volts AC power. 2 Years parts and labor warranty...be sure and send in the warranty card. White in color. 1 per package.
