Because sail boats generally sit lower in the water and have less glass than power boats, they tend to produce more duct condensation than the power boat, however, space restraints may not allow the total use of insulated duct and you may need to use a combination of the two duct types. Some situations will require the use of non-insulated duct, but will require insulating the duct after the installation with a insulation wrap. All duct runs should be as short and straight as possible. Every 90 degree turn in a duct run reduces performance by about 14%. Ducting should be tied to a permanent structure every foot or two to eliminate sagging. Using tie wraps, insure ducting is appropriately fastened to each supply air grill. Another important consideration is the physical size of the supply air grills. Four inch round grills require a 4.5 inch hole and the duct merely slides over the neck of the grill. A four inch rectangular grill usually measures 4x8 inches for the hole size but also requires a plenum or transition box behind the grill, also measuring 4x8 inches and extending approximately four inches behind the wall. These boxes are needed to attach the air duct to the grill and are required for every size rectangular supply grill. We suggest that you lay out a simple sketch of your boat on paper and then over lay your ducting scheme. Take this diagram on board and make measurements to be assured that the scheme is attainable. Remember once committed, "holes are forever". If you need help or would just like to discuss your installation with an experienced technician, give us a call. Mermaid will be happy to aid you in the layout of your duct and venting scheme. 5. Return Air : Sufficient cabin "return air" back to the air conditioner is just as important to the cooling of the boat and the performance of the air system as "supply air" is going into the cabin. Air conditioning is just that, conditioning of the air in a closed environment by continually pulling it back into the air conditioning unit, removing heat and moisture and sending it back into the room or cabin. It is important that the same volume of air being forced into the cabin is allowed to return to the air conditioner. As long as the physical opening of the return air grill is at least the minimum size specified below for your specific air conditioner, the actual shape of the grill is not important. Where it is not possible to have a single return grill multiple grills may be used. Make sure that the air conditioner evaporator (the front of the air conditioner resembling an automotive radiator) is not blocked or restricted from receiving the cabin return air. It must always be at least 3 or more inches from any bulk head or structure. Never stow items such as life preservers, bedding or other items of this nature between the evaporator and the return air grill. To allow better access to the air conditioner compartment during installation, do not attach the return air grill until the unit has been completely installed. RETURN AIR REQUIREMENTS MODEL BTU SQ.

High Pressure Switch Access: All Mermaid marine air conditioners utilize a manual High Pressure safety switch. This switch monitors the system’s high pressure any time the compressor is running. If a condition occurs that causes the system high pressure to rise to a level that could damage the compressor, the switch will activate and remove power from the compressor and pump. Once activated, this switch must be manually reset. The switch is a green cylindrical object with a red button . You must provide enough space to reach your hand into the compartment or cut an access hole in the cabinet above or alongside the switch to reset it after activation. When the air conditioner is operating in the cooling mode only the lack of sufficient cooling water can cause high pressure. In reverse cycle heat pump units operating in the heating mode, high pressure can only be created by over heating of the evaporator which is generally caused by insufficient return air or restricted supply air. The trouble shooting guide covers these and other problems. 7. Condensation Removal: Depending on the btu rating of your unit and the actual run time, the air conditioner will remove from one to five gallons of water (condensation) from the air in a 24 hour period. This water collects in the condensation pan to be drained out. Most boat owners will drain this water into the bilge for removal overboard by the existing bilge pumps. When running your condensation hose remember that condensation flows only by gravity and the hose must never rise up any where along the way or condensation will backup into the pan and overflow. This will not sink your boat, but it can get the surrounding area very wet. In many boats it is not possible to drain to the bilge, and the condensation must be removed by other means, such as a...
