    General info about the Self Contained Unit

    This unit has a capacity of 4,200 BTU as well as reverse-cycle heat, it also comes with a  high-velocity Blower so you have a marine air conditioning to suit your small cabin.This marine air conditioning is recommended for Sailboat and Powerboats. It is ideal for helms, mezzanines, crew cabins, guest cabins, etc. The unit utilizes R410A refrigerant to be very quiet and reliable. The 20 years rated CuNi 70/30 condensing coil we are using is very strong and durable compare to the competitors 10 years rated CuNi  90/10 condensing coil.  The chrome bezel for the control is included. Our display shows red for heat, blue for cool, and white for fan. 

    The unit has a multi-speed fan with automatic mode, an internal motor for a more compact installation footprint. The blower can be rotated to a horizontal or vertical position for greater installation flexibility. The Mabru Compact Self Contained is built on an easy-to-install stainless steel drain pan, and the return air filter is removable for cleaning. The unit will operate with the included LCD digital color control (chromed bezel display included) For convenience of installation, the electrical box can be mounted remotely.
