D. Nitrogen Vent Port
The Nitrogen Vent port of the machine is a ¼” x 45 SAE Male Flare fitting at the end of
a deflector tube located on the left side of the machine see figure-4. The tube is curved
downward to direct the stream of venting nitrogen away from personnel and to channel
condensation down and away from contact with the automatic valve of the machine.
Remove the cap and the bagged Deflector Tube from the Vent port.
Connect the Deflector Tube to the Vent Port finger tight. Then just lightly tighten snug with
a 5/8” open end wrench. Do not over tighten: this may twist the internal plumbing of the
machine.
The vent port must be plumbed to an outside area when processing FE25. Use
minimum 3/16” inside diameter plumbing. Be sure to route the plumbing so that moisture
condensing inside the plumbing will drain out and not back to the machine otherwise the
nitrogen vent valve may freeze in the open position resulting in total loss of the processing
Agent. Install screening at the end of the plumbing to guard against entry and clogging by
debris and insects.
CAUTION: DO NOT RESTRICT THE NITROGEN VENT PORT OF THE
MACHINE. Restricting the vent port may result in poor recycling quality.
