Sea Frost DC 5000 installation instructions Valve Unit V/U

VALVE UNIT V/U

For appearance and convenience of installation, the valve unit may be mounted outside the icebox. In certain applications and multiple plate systems it may be best to mount it inside. Location of the V/U in multiple plate systems is indicated in the design layout from our application engineer.

On an externally mounted V/U two 1/2" Swagelok fittings fasten the V/U to tubing protruding through the icebox wall. Before cutting the tubing:

•Leave a minimum of 1 1/4" of tube beyond the bulkhead.

•Allow room for wrench access.

On any installation:

•The Valve Unit may be mounted in any position.

•90-degree elbows can be factory installed on the Valve Unit to reduce the space requirements if necessary.

•The tubing will support the Valve Unit.

•The tubing must bottom in the fitting. For final installation of this unit see the Swagelok text.

•The V/U will attract moisture. If it is mounted externally to the cabinet be sure it is accessible for proper insulation installation after the system has been leak checked and operationally tested.

NOTES ON SWAGELOK FITTINGS

Swagelok fittings come to you completely assembled, finger-tight. (Pieces a, b, and c in Drawing #1 are already together). They are ready for immediate use.

Disassembly before use can result in dirt and foreign material getting into the fitting and causing leaks. If disassembly is necessary, reassemble per drawing.

This is a double ferrule system. The most serious installation problem encountered with SEA FROST is the incorrect assembly of these fittings. Be absolutely sure that you assemble all fittings as in Drawing #1.

To ease assembly slacken the fitting nut slightly before assembly. Then tighten with fingers before tightening with a wrench. (This is to avoid cross threading.)

Step 1. Always leave two inches of straight, undistorted tubing leading to all Swagelok fittings to allow proper connection.

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.
