Installation Guidelines for the CHC Chiller Compact

When choosing the proper model CHC Chiller Compact condensing unit, primary consideration should be given to calculated BTU loads and avialable power supply. Any special requiremnts(capacity modifications, voltages, cycyles , auxiliary heat, etc.) should be determined prior to installation.
The location of the Chiller Compact condensing unit shiuld be dry and accessible for service, typically in engine room, lazarette or machinery compartment. Secure the condensing unit to a level horizontal surface with the supplied brackets. These brackets are designed to hold the weight of the equipment as well as handle any torsional movement. Do not stack units directly on top of each other as each condensing unit must be independently supported. Racking is avialable to facilitate custome installtions.
Reinforced marine grade hose is to used for the seawater circuit. The hose is to be routed upwards from the thru-hull intake to the condensing unit to prevent air locks in the centrifugal seawater pump. Circulation connections between unit and chilled water lines are to be made with properly sized fittings and reinforced marine grade hose. All hose connections are to be double clamped and aball valves should be installed at ashilled water inlet / oulet of each air handler for ease of serviceability of the system. Insulate all hose and fittings airtight upon completion of leak tests to prevent condensation and capacity loss.
The condensing unit chassis has a integral condesation drain pan for removal of any water that may form. Secure a hose to this drain pan spud and route it downward to a proper sump or overhead discharge outlet.
Never install the air handlers in bilge or engine room areas and insure that the selected location is sealed from direct access to bilge and/or engine room vapours. Do not terminate condensate drain lines within three(3) feet of any outlet of engine or generator, nor is 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 vapours to mix with the air handler's return air and contaminate living areas.
All circuit breakers and wire gauge must be sized according to marine design standards. Only stranded tinned copper wire should be used. Route all wiring through the strain-relief provided in the electrical boxes.
All equipment should be properly grounded and bonded. Electrical boxes are pre-wired for power with solid state control circuits. The system control switch can either be mounted on the moduke or remoted on a panel for more convinient access.
All chilled water condensing units use closed-refrigerant circuits, pre-charged with R-22. No addtional refrigerant is required during the installation or at intial start-up and operation of the system. Refer to other individual component sheets for specifications and details of air handlers, controls and related parts.
In keeping with regulations set forth by the EPA, only certified technicians should perform service on, or make adjustments to, any refrigerant circuits. However, this is not necessary when installing Chiller Compact modules.
