6k to 16k Condensing Units
PRODUCT DESCRIPTION
Central System Condensing Units are available in capacities ranging from 6,000 to 16,000 BTU, in both reverse cycle and cool only. Each model is available for 115 volt or 230 volt operation, at both 50 and 60 cycles.

High efficiency compressors are incorporated to provide significant reductions in amperage draw. Each unit is hermetically sealed and ignition protected. Pressure switches and thermal overloads afford system protection.

Condenser coils are constructed of spiral, fluted cupronickel enclosed in a copper shell to provide high corrosion resistance for continual sea water flow. All surface components are constructed of, or coated with, materials resistant to fire and corrosion. Each unit is prime-coated then sprayed with a polar white finish.

Central System Condensing Units can be installed in any convenient location and are unaffected by vibration, moisture or ambient temperatures up to 140*F.

Installation Guidelines for 6k to 16k Condensing Units

When choosing the proper model Condensing 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 sea water temperature. As it decreases, the unit's 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.

The location of the Condensing Unit should be dry and accessible for service, and provide the most direct routing of refrigerant line sets relative to the evaporator location(s). The vibration isolated condensing unit should be secured to a horizontal shelf that is designed for the weight of the unit and torsion loads from the vessel's movement.

Refrigerant-grade copper tubing should be properly sized for the specific application. Both the suction and liquid lines should be insulated separately with approved closed cell foam jackets (i.e., Rubatex 1/4" wall thickness). The refrigerant line ends should remain capped until the actual connections are made to prevent contamination. To prevent kinks in the tubing, which will adversely affect the performance and longevity of the system, tube benders are recommended.

When using multiple evaporators with one condensing unit, locate all unions and tee fitting properly in areas accessible for service. Use approved flaring techniques and refrigerant grade components for all connections.

Insulate using cork installation tape or foam tape (only after system has been leak-checked). Wrap fittings sufficiently to equal R-value of tube insulation. Reinforced marine grade should be used for the sea water circuit. All hose fittings should be double clamped. The hose should be routed upward from the thru hull intake to the condensing unit to prevent air locking and provide draining of the sea water circuit. The condensation drain should be connected and routed downward to a proper sump or overboard discharge.

All circuit breakers and wire gauge must be sized according to marine design standards. Only stranded tinned copper wire should be used. All equipment must be properly grounded.

The installed line sets and evaporator(s) must be evacuated to remove air from these components and prevent moisture acidity formation. All connections should be properly leak-checked upon releasing the refrigerant charge must be "pumped down" back into the condensing unit or recovered to prevent it from escaping into the atmosphere.

Refer to other individual component sheets for specifications and details of evaporators, controls and related parts.

In keeping with regulations set forth by the EPA, only certified technicians should perform service on, or make adjustments to, the refrigerant circuit.
