Quiet, efficient cooling

Designed for small cabins, Dometic’s Cuddy II 12 V DC-powered air conditioner is a self-contained, water-cooled unit for boats cruising in either freshwater or saltwater. The unit draws power gently at startup for a progressive low starting surge. Built for dependability, the Cuddy II has a stainless steel base pan that is insulated to prevent sweating and minimize movement and sound. The evaporator coil of lanced aluminum fins and rifled copper tubing is dipped in a protective polyester enamel. The compact motorized impeller moves air quietly and efficiently through ductwork and grille. Protective features include independent locked-rotor protection on the compressor and air mover. Under voltage protection shuts down the compressor and air mover if voltage is less than 10.5 V. The Cuddy II benefits from thermal protection and polarity protection. Installation is easy with a readily accessible terminal strip for both the 12 V DC power input and the thermostat wiring. There are condensate connections on 3 sides of the base pan, and hold-down clamps are also included. The Cuddy II uses environmentally friendly R-134a refrigerant, and comes factory charged, wired, and tested. To conserve space, the control box is mounted remotely from the air conditioner on a 4.5 ft. (137 cm) heavy-duty cable.
