The Dometic ATL-DC 12,000 BTU/h 230 V/50-60 Hz/1-Ph chilled water air handler represents an improved design approach to low-profile, draw-through air handlers. This "open top" unit allows for easy maintenance access and every detail has been considered to make the unit as compact as possible. The ATL-HV series feature dual high-velocity (HV) blowers for effective air distribution. Optional "WhisperCool" DC blowers are available for an even quieter performance. All ATL blowers are mounted horizontally for an exceptionally low profile, making these units ideal for height-restrictive installations. They can be suspended from above or supported from below for flexible installation options. Suspension hardware is included. Vibration-isolation mounts reduce noise and the transmission of vibrations to the installation platform. The drain pan has an anti-slosh, anti-fungal foam lining and extends under the valve motor and plumbing. The water connections are insulated against secondary condensation, and the valve can be mounted on the left (standard) or right (optional).
