Mermaid M6 Cool & Reverse Cycle Marine A/C Unit - 6,500 BTU's - 230V 

With a cooling capacity of 550 cubic feet, the Mermaid M6 marine A/C unit is designed to cool up to a 27′ cruiser or a 30′ sailboat. Mermaid units pack the perfect punch of cool, comfortable air to keep your cabin temperate.

Mermaid uses 4" ducting and recommends a minimum of 2, 4" round supply grills with this installation. This unit will run off the new Honda eu1000i 1,000 watt portable generator, while in cool mode. Another option is to use a Statpower 1,000 Watt Inverter and 450 amp hours of battery power and you can anchor out (on average) for one night. This unit is available in right, left or top air discharge configurations.

All M6 models include a digital thermostat, an insulation mounting pad, and an air output collar. Pump not included.

With Reverse Cycle Heating 

With reverse cycle heating in a marine A/C unit, a reversing valve reverses the flow of freon. Normally the evaporator / fan blows cold into the cabin while the condenser expels the heat into the water. When reversed, the evaporator / fan blows heat into the cabin and the condenser expels the cold into the water. Unit BTU ratings are based on it’s cool mode. The reverse cycle heat mode produces 10-15% more BTU’s than the unit does in cooling mode.

Digital Control/Thermostat Options (Included w/Unit) - Select Programmable or Non-Programmable 

Programmable Thermostat

Mermaid’s standard Digital Programmable Thermostat. Designed to be used with any Mermaid unit. 

Programmable features allow for weekday and weekend setting for those boater’s who care to use the unit for dehumidification or simply climate control while not on board. The thermostat is also accompanied with 20 feet of four-wire thermostat cable and installation instructions.

Dimensions: 4 1/2″ length x 1 1/4″ width x 3 1/4″ height

Non-Programmable Thermostat

As an alternative to the standard Digital Programmable Thermostat, Mermaid offers a simple Non-Programmable Thermostat that can be mounted vertically or horizontally. It is ideal for applications where programming features will not be necessary.

Simply turn the unit to HEAT or COOL, set the fan to AUTO (comes on with the unit) or ON (continuous duty), and set your desired temperature – and that's it! The thermostat will now maintain that set temperature until you turn it off or change the temperature. Again, this item is ideal for folks looking for a simple controller and a slimmer wall mount design. This can be a FREE alternative to your Programmable Thermostat upon purchase of any Mermaid Air System. 

Dimensions: 4 5/8″ length x 7/8″ width x 3 1/4″ height
