START UP PROCEDURE AND PERIODIC INSPECTION

ATTENTION new SEA FROST owner or operator! PLEASE DO NOT OPERATE THE REFRIGERATION SYSTEM UNTIL YOU READ THIS.

WARNING! Your SEA FROST System can be severely damaged and your warranty will be invalid if these steps are not followed closely. Please read the information here before proceeding to operate your system for the first time.

BREAK-IN PERIOD. LIMIT COMPRESSOR RUNNING TIMES TO THIRTY MINUTES FOR THE FIRST TWO HOURS OF OPERATION. THIS SHOULD BE FOUR SEPARATE THIRTY-MINUTE OPERATIONS WITH A REST PERIOD OF AN HOUR OR MORE BETWEEN THEM.

1)Locate the SEA FROST Receiver/Filter/Drier (RFD). The location of this part varies from boat to boat, but it is often found in the compartment with the DC 5000, in a locker, or beneath the cabin sole. It is a blue metal can about 9 inches high and 3 inches in diameter, with brass fittings connecting it to copper tubing. If you do not locate the RFD quickly, follow the route of refrigeration copper tubing, from the DC 5000 to the icebox. Along the route you will find the RFD. The RFD has a sight glass for viewing the flow of refrigerant.

2)Check to be sure the proper sea cocks are open.

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)With the system running look at the sight glass in the RFD.

5)MONITOR THE SIGHT GLASS CONTINUALLY. 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, that is, if the sight glass does not show the presence of refrigerant within a minute or two of operation the system is dead flat. DO NOT

CONTINUE TO OPERATE THE SYSTEM. OPERATION IN THIS MODE WILL RUIN THE COMPRESSOR. Switch off the DC 5000 to prevent operation until the problem is corrected. CALL US AT 603-868-5720.

6)If white foam is evident watch closely for a transition from foam to clear: a clear sight glass indicates a sufficiently charged system. This point can be missed if proper attention is not given. A FULL SIGHT GLASS AND AN EMPTY GLASS LOOK THE SAME! It is possible for the sight glass to show large, almost stationary bubbles even when the charge is sufficient, so it is important to differentiate between "foam" and larger “bubbles”. The foam condition has velocity and direction, but the larger bubbles are nearly stationary. If the foam does not clear, the system is low on charge. CALL US AT 603-868-5720 for trouble shooting and correction help.
