Installation Guidelines for Cabin Mate
When choosing the proper model Cabin Mate 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
boat 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
warmair.It is not recommended that the unit be operated in the heat cycle withwater temperatures below 40
°
F (4.4
°
C).The location of the Cabin Mate self-contained unit should be dryand accessible for service.Placement of the unit should be adjacent to alow 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
marine air conditioner 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 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 ductingshould be 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 areavailable 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 marinedesign 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.
