Choosing a good water pump for marine air conditioner is basic for the good performance of the system and also for the boat safety.
Boat air conditioner not pumping water.
Circulation pump duty is taking the raw water from the sea that air conditioner will need for cooling.
The rule of thumb is to have 180 gallons per hour 3gpm of water per ton of air conditioning one ton is 12 000 btu hr.
The table below shows recommended seawater flow rates and minimum inlet through hull for a system of a given capacity.
Many skippers never switch to reverse cycle but they should.
The air conditioner does not release water.
The dometic reliable the heavy duty centrifugal pump provides a steady flow of cooling water through the air conditioning system.
Investing in air conditioning for boats does not need to be extremely burdening primarily if you can afford to invest in premium quality options.
Marinaire 16000 btu h self contained marine air conditioner and heat pump.
The thermostat should be in off position.
Here your boat s ac unit works normally but it s not discharging any water.
The dometic pma1000 pump can support total air handler capacities from 16 000 to 42 000 btu h and ensures top cooling performance.
Of course it is for the best to administer exhaustive research first since buying topnotch air conditioning units.
Inspect the raw water strainer and flush if dirty or clogged.
There s a reversing valve in the system that can stick if it s not activated regularly.
Most marine air conditioners have a reverse cycle mode which changes the flow of refrigerant and turns the system into a heat pump.
If more than one marine air system shares a common pump you will also need a pump relay and manifold.
