BG 2000 MAINTENANCE
Like your engine, your SEA FROST needs periodic checking.
ROUTINELY CHECK:
1. The refrigerant charge. See: "Checking The Charge" text. NEVER OPERATE
SYSTEM WITHOUT PROPER CHARGE.
2. All components, all tubing, fittings, and hose clamps for corrosion and wear. BE
SURE TO LOCATE AND INSPECT ALL FITTINGS AND COMPONENTS IN THE
SYSTEM. KNOW THE LOCATION OF ALL CONNECTION POINTS. Spray with a rust
inhibitor REGULARLY. Corrosion unchecked in the marine environment will severely
reduce the life of your system.
CLEANING
The holdover plate surface protects itself with a layer of oxidation. You might find
that after a long period of storage the plate will look chalky. This will not effect operation
and is easily cleaned up with a pot scrubber and soap.
WATER STRAINER
The water pump must be protected from damage and blockage by a seawater
strainer. This strainer must be inspected and cleaned routinely.
ROUTINE SERVICE AND INSPECTION
We recommend sea strainer inspection before leaving the boat unattended dockside
with the unit on. A visual inspection may be adequate depending on the type of
strainer. To clean most types of strainers, close the seacock, open the strainer, remove
the screen or basket, clean, reassemble and open the seacock. Operate the system
and check for water flow and leaks around the strainer opening.
PUMP IMPELLER INSPECTION (if pump is inoperative)
The LC-3P pump is a sealed liquid cooled magnetic drive centrifugal pump. The
impeller may be inspected for obstructions and wear by first closing the seacock. Drain
the pump housing by removing a hose.
