8.Leak check the capped connection service ports with the leak detector.

9.Spray the acrylic coating, or similar rust inhibitor, on all the fittings and components when they are dry.

10.Finish insulating the V/U, suction line and any suction line connectors.

11.BREAK-IN PERIOD. During the first four hours of operation of a new compressor, limit the compressor running times to thirty minutes with an hour rest period.

READING THE SIGHT GLASS

A clear sight glass when the compressor is operating signifies a sufficiently charged SEA FROST DC 5000 System. To determine the meaning of "clear", notice the appearance of the RFD sight glass when the system is at rest with the compressor off. This is a "clear" glass.

WARNING: A clear sight glass can also indicate a completely EMPTY system. Anytime the compressor is started, white foam should appear in the sight glass indicating that refrigerant is present. This foam may disappear quite quickly, but IF NO FOAM IS EVIDENT and the system is not cooling, the system is empty. DO NOT OPERATE THE SYSTEM in this empty condition. Operation in this mode will ruin the compressor. Be sure to disable the system (Disconnect wiring.) to prevent operation until the problem is solved.

Fast moving white foam with the compressor operating indicates an insufficient charge level. Watch closely for a transition from foam to total liquid, indicated by a clear sight glass. This transition point can be missed if proper attention is not given. Also, IT IS

POSSIBLE for the sight glass to show large bubbles even when the charge is sufficient, so it is important to differentiate between "foam" and "bubbles". The foam condition has velocity and direction; the bubbles are large, temporary, and nearly stationary. Do not try to chase away these larger bubbles with more refrigerant: overcharging will then occur. Air in the system may give a false sight glass reading, which could lead to overcharging. If in doubt, discharge a suspected overcharged system to continuous foam and slowly add refrigerant to clear the glass. Monitor the sight glass continually since the glass will not indicate when the system is overcharged.

In a warm system, when the plate is above freezing (32.F) upon start-up, the sight glass may take several minutes to clear. A cold system, in cold water, may show a clear glass within seconds of start-up.

DC 5000 specifications

The Sea Frost DC 5000 is a cutting-edge refrigeration system designed for marine and offshore applications. Known for its reliability and efficiency, the DC 5000 offers superior cooling solutions that are essential for preserving food and other perishable materials on boats and yachts.

One of the standout features of the Sea Frost DC 5000 is its dual refrigeration capability. The system can operate both as a freezer and a refrigerator, allowing users to tailor their cooling requirements based on their specific needs. This flexibility is particularly advantageous for marine environments where space is limited, and energy efficiency is critical.

The DC 5000 is powered by advanced technology that includes a high-efficiency compressor. This compressor is designed to provide powerful cooling while consuming minimal energy, making it ideal for use in remote locations where power resources may be scarce. Coupled with an innovative digital thermostat, the system allows for precise temperature control, ensuring that food remains at optimal storage conditions.

In terms of build quality, the Sea Frost DC 5000 features robust construction that is resistant to the harsh marine environment. It is engineered with high-grade materials that can withstand exposure to saltwater and humidity, reducing the risk of corrosion and ensuring a long service life. This durability is complemented by a compact design that comfortably fits in various spaces on a vessel without compromising usability.

Furthermore, the Sea Frost DC 5000 incorporates a user-friendly interface, providing sailors and boaters with an easy way to monitor and adjust the cooling settings. The system is designed for low noise operation, allowing for a serene onboard experience without the distraction of excessive sound.

A significant advantage of the Sea Frost technology is its ability to run effectively off both AC and DC power, providing flexibility and adaptability in power source selection. This feature ensures that users can always keep their perishables cool, whether docked at a marina or cruising offshore.

Overall, the Sea Frost DC 5000 stands out as an exemplary refrigeration solution for marine use. Its combination of advanced technology, durability, energy efficiency, and user-friendliness make it an essential component for anyone looking to maintain food quality and safety while at sea.
