Self-ContainedReverse Cycle Air ConditionersModels MAB 07-10-12-16-24AR-410 ntre aRefrigGeneral DescriptionMarvair's water source self-contained reversecycle air conditioners are designed for usein either fresh or salt water. These units arebuilt in capacities of 7,000; 10,000; 12,000;16,000; and 24,000 BTUH. The self-containedunits are complete packaged units, factorycharged and wired.A Marvair Marine first - a universal controlboard for all products - makes replacementquicker and easier and reduces the stockingrequirements of service centers.MAB16RCLess Watts: High efficiency Tecumseh and Copeland compressors More heat transfer with the cupronickel, eight volute, multi-lead inner tube. Theconvolutions increase heat transfer and refrigerant turbulence further enhancing thethermal performance, while inhibiting the accumulation of deposits in the water tubing. Powerful, backward inclined impeller moves the conditioned air effortlessly throughduct.More Air Flow with Marvair’s Unique Box Blower : Three duct outlets eliminate the need to rotate the blower, saving installation time. No air distribution box required on the unit. Two to three dBA quieter than conventional centrifugal blowers.Less Space – Our Most Compact Unit Stainless steel condensate pan – no flimsy condensate connections. Baked polyester coil rated to 1,000 hours in salt spray test. Rolled and embossed base pan adds structural support to all componentsUnits are available for operation on 115V, 60 Hz; 208/230V, 60 Hz and 220/240V, 50 Hz.The units are built using R410A refrigerant. R410A is environmentally friendly, non-ozonedepleting and accepted for use throughout the European Community.The reverse cycle air conditioners feature rotary and scroll compressors with a suctionline accumulator and high and low refrigerant pressure switches. The coaxial tube-intube condenser is constructed of corrosion resistant cupronickel water tubing and copperrefrigerant tubing.To ensure years of dependable performance, the units feature: A stainless steel base pan with multiple condensate drain openings allows the rapiddisposal of condensate. The base pan is embossed to add rigidity and to keep thecomponents out of the condensate. An insulated pad minimizes movement and sound. Structural supports, blower housing and control box constructed of superior corrosionresistant aluminum. The aluminum is primed and then a white heat cured polyesterfinish is applied for the optimum in durability and aesthetics.MAB Selfself Containedcontained PDS 1/2011MAB1
A five foot long (151 cm), heavy duty multiwire cable harness facilitates the remote mounting of the controlbox. This complete cable assembly seals all the wires into the harness to minimize the chance of corrosion. The evaporator coil is constructed of lanced fins and rifled copper tubing for optimum heat transfer. The coilhas a baked polyester enamel finish - no paint - and is rated to 1,000 hours when tested to ASTM B117. A compact, motorized impeller type blower moves the conditioned air quietly and efficiently through duct work.Backward curved, corrosion resistant centrifugal fans feature extremely long blades for high efficiency and lownoise. Maintenance free ball bearings never need oiling.All units are built to the requirements of UL standard 484, 7th Edition. Marvair is an ISO 9001-2008 registeredcompany. All self contained and split systems units (unless designated otherwise) meet applicable ABYC andUS Coast Guard regulations, CE directives, and all applicable Air Conditioning, Heating and Refrigerationstandards.InstallationInstallation of units is simplified with a readily accessible terminal strip for both the power and control (lowvoltage) wiring. The control box is located on the side of the self contained units. However, the control box canbe easily mounted on the opposite side or remotely mounted on a bulkhead. A five foot (151 cm) multiwire cableharness provides a durable and quick electrical connection between the unit and the control box. Condensateline ports (5/8” nylon tube) on both ends and both sides of the base pan facilitate the drain line connections.Factory provided hold-down clamps are included.ThermostatsAll units can be controlled by either the o-Touch, o-LED or the MachAir I thermostat/controller. The o-Touch,o-LED and the MachAir I thermostat/controller display shows whether the unit is in the heating or cooling or fanonly or dehumidification mode, set point temperature ( F or C), cabin temperature ( F or C) and fan indicator.The cooling or heating can be selected manually or the Auto mode selects whichever is required automatically.The fan speed can be controlled automatically or manually. Includes wall mounted controller/display. See theProduct Data Sheet for complete information on the thermostat/controllers.AccessoriesAccessories are required and ordered separately.

Each opening is a 9-7/8" x 4" (251mm x102mm) oval opening. An oval adapter, Marvair part number 91568, should be used as a transition to duct on each opening. Thisadapter has an outside diameter of 10" x 4" ( 254 mm x 102 mm). For optimum performance, both openings must be used. Insufficientair flow can cause ice to form on the evaporator coil in the cooling mode and premature activation of the circuit breaker in the heatingmode.MAB self contained PDS 1/20116
