Claim 3:
4. The method of claim 1 comprising the further step of providing a recovery port bleed valve subassembly secured to the recovery port and comprising:
a bleed valve port defining an outer port channel and an inner port channel;
a bleed valve port valve stem dimensioned to fit within the outer port channel and the inner port channel, wherein the bleed valve port valve stem defines a recovery port valve stem channel and a radially disposed, recovery port valve stem bore that intersects the recovery port valve stem channel and provides fluid communication between the recovery port valve stem channel and the outer port channel and the inner port channel; and,
an adjustable recovery port valve cap having an inner wall that defines a recovery port valve cap channel, wherein the inner wall is formed with a helically oriented slot dimensioned to receive a pin secured to, and projecting from, the bleed valve port, wherein rotation of the valve cap about the recovery port causes the pin to move along the slot to move valve stem into, and out of, the bleed valve port.
