For gravity oil feed system, the oil reservoir should be installed a minimum of six feet above the oil level regulator. During start up of the system, compressor refrigeration oil should be added to the oil reservoir to the upper sight glass port, not above it. If the oil level in the reservoir will fall under the lower sight glass level, oil have to be added.
High pressure gas returns the oil from the oil separator to the oil reservoir. Pressure could build up in the oil reservoir to adversely affect the oil regulators. To prevent this, a vent line is installed from the top of the oil reservoir to the suction line. This line permits the pressure in the oil reservoir to be approximately the same as the suction line and the compressor crankcases.
