GENERAL DESCRIPTION

The SEA FROST DC 5000 is a cold storage refrigeration system powered by a 1/2 horsepower permanent magnet direct current 12-volt motor. Refrigerant from the compressor is piped to the SEA FROST plate in the icebox. Cold storage is attained by rapidly freezing the solution contained in the plate, creating a captive (replenishable) block of ice. The system may be used when the boat’s engine is on and charging the batteries or with a properly sized battery bank. The compressor may be controlled by an oil pressure switch preventing operation without the engine, a lockout relay that prevents operation without the shore power charger operating, a timer, or by a thermostat alone. The heat removed from the icebox is discharged into the seawater at the water-cooled heat exchanger. A separate pump below the water line controlled by the DC 5000 pumps water through the heat exchanger and overboard above the water line.

BREAK-IN PERIOD.

REFER TO THE START UP PROCEDURE IN THE BEGINNING OF THIS MANUAL. EVERY TIME THE SYSTEM IS RESTARTED FROM WARM, CHECK TO BE SURE IT IS COOLING BEFORE OPERATING THE COMPRESSOR EXTENSIVELY. THIS IS YOUR SYSTEM. SIMPLE OBSERVATIONS OF YOUR SYSTEM AND OPERATING CAUTION WILL PREVENT DAMAGE THAT COULD COST YOU MONEY.

OPERATION

1.This system is water-cooled and depends on water being pumped by the remote DC 5000 pump. The proper sea cock must be open before starting the system. Water flow is most important, therefore CHECK THE WATER FLOW AFTER STARTING THE SYSTEM.

2.Check the battery switch position and voltage readings before starting.

3.Start the DC 5000 by turning on the thermostat. The red indicator light should light, indicating 12-volt power is available and that the system is operating. Check the overboard discharge to be sure water is being pumped.

4.If the battery system is fitted with an amp/hr meter you will notice the DC 5000 compressor drawing about 45 amps/hr (12 volts) for the first few minutes dropping to 35 amps/hr for the remainder of the cycle.

5.After 10 minutes of operation, check for a drop in the cold plate temperature by feeling the plate with your hand. If no noticeable cooling has occurred, turn off the thermostat. Check the charge level (See checking the refrigerant charge section) and check the water flow. TO PROTECT THE COMPRESSOR, DO NOT OPERATE the system if this temperature drop is not noted.

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.
