Mermaid M6 6,500 BTU Reverse Cycle (110V) Service & Performance Guide
What are the power specs for the Mermaid M6 110V?
The Mermaid M6 110V (60Hz) is the standard small-capacity unit for North American boats, drawing approximately 6.2 Amps. This 6,500 BTU reverse-cycle unit can run on a standard 15A shore power circuit with plenty of headroom for other electronics. It is the perfect air conditioner for 25-30 foot sailboats or small pocket cruisers requiring both cooling and heating.
Does the Mermaid M6 110V provide heating?
Yes, this model features a Reverse Cycle heat pump that provides 6,500 BTUs of warmth during the shoulder seasons. It is an "All-Season" unit that eliminates the need for bulky portable heaters in the cabin. Note that for heating to function, the boat must be in water above 40°F (4.4°C) to allow the refrigerant to extract heat from the surrounding environment.
What pump size is needed for the Mermaid M6 110V?
The Mermaid M6 110V requires a marine centrifugal pump with a minimum flow rate of 200 GPH. A consistent water supply is critical for both the cooling and heating cycles of this 6,500 BTU unit. Ensure the sea water pump is mounted below the waterline to maintain a constant prime and prevent the unit from tripping on high-pressure safety codes.
How do I clean the M6 110V air filter?
The Mermaid M6 110V features a reusable mesh air filter that should be inspected and rinsed with fresh water monthly. Keeping the filter clean prevents dust buildup on the evaporator, ensuring maximum airflow and cooling efficiency in small cabins. A clean filter also helps the unit dehumidify more effectively, keeping the cabin dry and mold-free.
What is the installation footprint of the M6 110V?
The Mermaid M6 110V is one of the most compact 6,500 BTU units available, with a dry weight of just 35 lbs. Its small base pan allows it to fit into tight lockers or under-berth areas that larger units cannot occupy. When installing, ensure there is sufficient clearance for the 4-inch ducting and that the unit is secured using vibration-absorbing mounting grommets.
