FLOTLWWW” UNITS, 30GB040-200 (See Fig. 2.)

Bvnass Line - Connect the field-supplied line to the factory-provided stubs in the discharge line *fro-m the circuit no. 1 compressor and in the circurt no. 1 hquld line, between expansion valve and cooler (stubs are sealed from factory).

Bypass Valve - Install the valve in the bypass line as close to the cooler as possible. This mimmrzes liquid storage between valve and cooler when valve is closed and prevents flood of liquid refrigerant when the valve opens. To ensure proper closing, install the bypass valve in a horizontal section of the bypass line, with the pilot valve installed vertically (coil on top).

Solenoid Pilot Valve - Install on the bypass valve at the external equalizer @/&in. OD sweat connection). The outlet side of the pilot valve is a l/4-in. SAE thread. Run a l/4-in. OD tube from this connection to the thermo- static expansion valve (TXV) equalizer line, If the connection is made directly to the TXV, use a l/4-in. FL x l/4-in. female flare tee. If the connection is made into the equalizer line, use a standard l/4-in. FL tee.

Bypass Line - Install field-supplied line between the header on inlet side of lead coil and the entrance to the cooler. Two factory-sealed stubs are provided in each circuit, one on the lead coil header and one on the liquid line between the Flotronic expansion valve (EXV) and the cooler.

NOTE: The 30GB 1 lo-200 units have 2 stubs in the high side of each circuit, one on each lead coil header; it is necessary to connect piping to only one of these stubs.

Bvpass Valve - Install the valve in the bypass line as close to the cooler as possible. This minimizes liquid storage between the valve and cooler when valve is closed and prevents flood of liquid refrigerant when the valve opens. To ensure proper closing, install the by ass valve in a horizontal section of the bypass line, wit R the pilot valve installed vertically (coil on top).

Solenoid Pilot Valve - Install on the bypass valve at the external equalizer. The outlet side of the pilot valve is a l/4-in. SAE thread. Run a l/4-in. OD tube from this connection to the suction valve of the lead compressor in the circuit.

NOTE: Circuit 2 should be piped same as circuit 1. The %-in, tube should be connected to the lead compressor in both circuits.
