The oil return pipe should be connected to the vapor phase part above the service tank, and no
shut off valve should be located on this oil return line. In addition, to prevent aeration into the oil
supply (delivery) pipe, the oil return pipe should be set apart from the delivery line and a baffle
plate should be installed on the return pipe. A flow meter should also be installed on the oil supply
(delivery) pipe to the oil service tank.
