Sea Frost BG 2000 RFD Sight Glass Detail, Proper Charge Amount, General Information

Page 25

A white stream of fast moving foam with the compressor operating indicates an insufficient charge level. Watch closely for a transition from foam to total liquid, indicated by a clear sight glass. This transition point can be missed if proper attention is not given. Also, IT IS POSSIBLE for the sight glass to show large bubbles even when the charge is sufficient, so it is important to differentiate between foam and bubbles. The foam condition has velocity and direction; the bubbles are large, temporary, and nearly stationary. Do not try to chase away these larger bubbles with more refrigerant; overcharging must be avoided. Air in the system may give a false sight glass reading, which could lead to overcharging. If in doubt, discharge a suspected overcharged system and charge again. MONITOR THE SIGHT GLASS CONTINUALLY. The glass will not indicate when the system is overcharged.

In a warm system, when the plates are above freezing (32.F) upon start-up, the sight glass may take several minutes to clear. A cold system, in cold water, may show a clear glass within seconds of start-up.

PROPER CHARGE AMOUNT

THE BG 2000 SYSTEM IS DESIGNED TO HOLD 24 OUNCES. THIS IS THE MAXIMUM CHARGE. The sight glass must clear by the time the return line (suction/large diameter tube) goes below 32 degrees F.

GENERAL INFORMATION

OPERATING PRESSURES will vary with water temperature, and water flow. Generally, the HIGH SIDE will peak with warm plates in two to four minutes. Increasing pressure indicates an overcharge or no water flow. The LOW SIDE will drop rapidly to the 20 to 10 range, and then slowly drop. The low side tubing will freeze. The low side pressure will drop more rapidly when the seawater is cold. A deep vacuum indicates the system is frozen with moisture or the valve is plugged with dirt or contaminants. Failure to "pull down" indicates the valve is malfunctioning or flooding.

The compressor will feel warm in normal operation.

Every valve has been operated prior to shipment. There are no field superheat adjustments.
