When choosing the proper model Mariner
condensing unit, primary consideration should be give to calculated
BTU loads and available power supply. Any special requirements
(number of boxes and/or controls, refrigerant line lengths, wiring
sizes, etc.) should be determined prior to installation.
The location of the unit should be dry
and accessible for service. It is not recommended to locate the unit
in an area that exceeds a continuous maximum temperature of 104*F.
The location of the unit should provide for proper air flow through
the air cooled condenser, if added, to avoid overheating the system.
The unit should be installed with the
fasteners provided, and secured to a horizontal surface sufficient
to support the weight and torsion load from the vessel's movement.

The sea water system must be installed
below the water line and routed on a continuous incline from a
dedicated thru-hull intake to the pump inlet, up to the condensing
unit to prevent air locks in the sea water pump. Reinforced marine
grade hose should be used for the sea water circuit, and all
fittings should be double-clamped.
The refrigeration lines connecting the
holding plate(s) to the condensing unit must be constructed from
refrigeration grade, dehydrated copper and must be properly
insulated (suction line only or both lines insulated together).
All fittings are designed to use flare
connections, and these connections are to be made using proper
flaring tools and techniques during
