It is IMPORTANT that NO WATER flows between the plastic housing and the pump body. The screws that hold the cover also seal the housing. Water behind the housing will ruin the motor bearings.

BE SURE THE PUMP HOUSING IS ABSOLUTELY DRY BEFORE DISASSEMBLY.

Remove the phillips screws holding the inlet fitting plate (larger hose size). The impeller may then be removed along with it’s ceramic seal and thrust washer. Reassemble in the reverse order. (An exploded diagram is in this manual.) Observe the "O" ring that seals the housing cover plate. Make sure it is in good condition. Open the seacock. Inspect for leaks.

NEVER OPERATE THE PUMP WHILE DRY. IF IT IS SUSPECTED THAT THIS CONDITION HAS OCCURRED, INSPECT THE IMPELLER AND HOUSING FOR WEAR.

CHECKING THE REFRIGERANT CHARGE

SIGHT GLASS LOCATION

The BG 2000 system is fitted with a sight glass located in the top of the RECEIVER/FILTER/DRIER (RFD). (The RFD is a round blue canister about 9 inches high and 3 inches in diameter. It is located in the left corner of the compressor housing.)

The charge level should be inspected to be sure refrigerant is of the proper amount and that there are no slow leaks. Switch the unit on and immediately inspect the sight glass. White foam with high velocity should be observed and after a minute or two show a black or clear condition. A clear glass and an empty glass will look the same. A transition must be seen to be sure that refrigerant is present. Do not operate a low or empty system. See; "Leak Checking” and “Adding Charge". (Page 22)

LAY-UP (Winterizing)

Flush the pump and condenser with plenty of fresh water. Pressure water should be flushed through the inlet side of the water pump. In freezing climates antifreeze should be pumped through, after flushing, by operating the system for a very brief period. Connect a short hose to the suction side of the pump to draw from a bucket. Run the pump (switch on unit) until antifreeze is discharged. (The pump is not self-priming and may require filling the hose and pump with a funnel). DO NOT RUN THE PUMP DRY. It is water lubricated.
