Installation Guidelines for Vector Compact

When choosing the proper model Vector Compact self-contained unit, promary consideration should be given to calculated BTU loads and available power suppley. Special consideration should be given in determining the reverse cycle heting capacitied under anticipated condidtions. 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 temperatures below 40 ° F (4.4°C).

The location of the Vector Compact self-contained unit should be dry and accessible for service. Placement of the unit should be adjacent to a low return 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 air condotioner in bilge or engine room areas. Insure that the selected location is sealed from direct access to bilge and / or engine room vapors. Do not terminate codensate drain lines within three (3) feet of any outlet of engine or generator , nor in a bilge (vapors can travel up the drain line), unless the drain is connected properly to sealed condensate or shower sump pump. Failure to comply may allow bilge or engine room vapours to mix with the air conditioner's return air and contaminate living area.

Grilles should be sized according to Marine Air design standards. Install the return air grilles low and the supply air grilles high. Return air grilles low and the supply air grilles high. Return air grilles must have removable filters installed if the filter on the unit is removed.

Ducting should be sized according to unit specifications. All ducting should be installed to be smooth, straight and taunt as possible, avoiding any unnecessary bends or loops. Once ducting runs are positoned properly they should be securely fastened to avoid shifting due to motion of the vessel.

Plastic vacuum-formed and insulated aluminium transition boxes are available for proper air - flow 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 design standards. 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.
