Installation Guidelines for AC Voltage/Hermetic Models - Caribbean
When choosing the Caribbean primary consideraion should be given to calculated BTU loads and availab;e 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 Caribbean system coponents should be dry and accessible for service. Compressor components must be installed near or on the main eingine with all
necessary components nearby. The remote junction box (optional) should be securely fastened using the mounting hardware provided.
The seawater system must be installed below the water line and routed on a continous incline from a dedicated thr-hull intake to the pump inlet, then up to the condensing unit to rpevent air locking of the seawater pump. Reinforced marine grade hose should be used for the seawater circuit, and all fittings are to be double-clamped.
The refrigeration lines connecting the holding plate(s) to the condensing unit must be constructed with refrigeration grade, dehydrated copper
and must be properly insulated. All fittings are designed to use flare connections, and these connections are to be made using
proper flaring tools and techniques during installation.
A non-leak compound may be used on flare connections, if desired, to prevent refrigerant leaks(due to vibration or loosening of suction side
connections due to frost). This compund should be applied sparngly to the male thread of the fitting, and great care must be taken to prevent contact with the flare
seat. Flare connections must be adequatey tightened - usually as tight as possible, with the exception of 1/4" lines
which can be crushed if the flare is over-tightened. All associated mechanical components (solenoid valves, check valves and expansion valves) must be located and secured properly.
Thermostats are to be located and properly secured in the box(es) or bulkheads with sensing bulbs properly secured into the sensing wells located on the
holding plates. Circuti reakers and wire guages must be sized according to ABYC marine design standards. Only stranded tinned copper wire should
be used. All equipment must be properly grounded.
Refrigerant line sets and holding plates must be thoroughly evacuated (recommended to 200 microns) and leak checked prior to releasing
refrigerant from the condensing unit into the system and start-up of the equipment. The refrigerant charge
may require adjustment once the entire system is operational. In keeping with regulations set forth by the
EPA, only certified technicians should perform service on, or make adjustments to, the refrigerant circuit.
