Installation Guidelines for Vector Compact

When choosing the proper model VectorCompact self-contained unit,primary consideration should be given to calculated BTU loads and available power supply.Special consideration should be given in determining the reverse cycle heating capacities under anticipated conditions.Reverse cycle operation is affected by the seawater temperature.As it decreases, the units heat transfer capacity also decreases and proportionately affects the output of warm air.It is not recommended that the unit be operated in the heat cycle with water tempera-tures below 40

°

F (4.4

°

C).The location of the VectorCompact self-contained unit should be dryand accessible for service.Placement of the unit should be adjacent to a lowreturn air access from the area to be conditioned.The unit should be installed with the proper fasteners and secured to a horizontal surface sufficient for the unit weight and torsional load from the vessel’s movement.Never install your boat air conditioner in bilge or marine engine room areas.Ensure that the selected location is sealed from direct access to bilge and/or engine room vapors.Do not terminate condensate drain lines within three (3) feet of any outlet of engine or generator exhaust systems, nor in a compartment housing an engine or generator, nor in a bilge (vapors can travel up the drain line), unless the drain is connected properly to a sealed condensate or shower sump pump.Failure to comply may allow bilge or engine room vapors to mix with the air conditioner’s return air and contaminate living areas.Grilles should be sized according to Marine Air design standards. Install the return air grilles low and the supply air grilles high.Return air grillesmust have removable filters installed if the filter on the unit is removed.Ducting should be sized according to unit specifications.All ducting shouldbe installed to be as smooth, straight and taut as possible, avoiding any unnecessary bends or loops.Once ducting runs are positioned properly they should be securely fastened to avoid shifting due to motion of the vessel.Plastic vacuum-formed and insulated aluminum transition boxes are available for proper air flow direction into any cabin or area.Ducting should be properly secured to these transition boxes to prevent air flow leakage.Built-in plenums or chases must be sized properly, completely sealed and insulated.Reinforced marine grade hose must be used for the seawater circuit.All fittings must be double hose clamped, reversing the clamps.The hose should be routed upward from the thru-hull intake, sea cock, strainer, pump, and to the condensing unit to prevent air locks in the centrifugal seawater pump.Circuit breakers and wire gauge must be sized according to marine designstandards.Only stranded tinned copper wire should be used. All equipment should be properly grounded and bonded.Ensure that power supply is turned off before opening electrical box.In keeping with regulations set forth by the EPA, only certified technicians should perform service on, or make adjustments to, the refrigerant circuit.
