START UP PROCEDURE
for
RECENTLY COMMISSIONED
SEA FROST ENGINE DRIVE SYSTEMS
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.
BREAK-IN PERIOD. DURING THE FIRST TWO HOURS OF OPERATION OF A NEW
COMPRESSOR, LIMIT RUNNING TIMES TO THIRTY MINUTES (FOUR SEPARATE
THIRTY MINUTE OPERATIONS WITH A REST PERIODS OF AN HOUR OR MORE)
AND ENGINE SPEEDS TO BELOW 1200 RPM.
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 engine compartment, in a locker, or
beneath the cabin sole. It is a gray metal can about 8 inches high and 2.5 inches in
diameter, with brass fittings connecting it to copper tubing. (If you do not locate the
RFD quickly, follow the route of 3/8" refrigeration copper tubing, the smaller diameter
tube, from the engine compartment to the icebox. Along the route you will find the RFD,
along with other SEA FROST components). The RFD has a sight glass for viewing the
flow of refrigerant.
2) Start the boat's engine. Check to be sure the engine is pumping water.
3) Locate the SEA FROST Control Panel. With the engine running at a fast idle (900 to
1200 rpm), and while looking into the sight glass, have a helper turn the timer knob past
"10" to cock the switch and start the compressor. The engine should load, slowing
slightly.
4) MONITOR THE SIGHT GLASS CONTINUALLY. White foam should appear in the
sight glass indicating that the refrigerant is present. This foam may disappear quite
quickly, but IF NO FOAM IS EVIDENT, that is, if the sight glass does not show a
presence of refrigerant within a minute 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 12-volt panel breaker to prevent operation until the
problem is corrected. CALL US AT 603-868-5720.
