IV. System Installation (continued)
B. Pressure Relief Valve Port
The Pressure Relief Valve port of the machine is a 5/8” x 45 SAE Male Flare fitting
located on the top of the machine see figure-4. The port is fitted with a plastic plug to keep
dirt and debris out of the valve. This plastic plug will be ejected if the valve operates. DO
NOT CONNECT ANY PLUMBING OR CAP TO THE PRESSURE RELIEF VALVE
PORT. This is a safety device that will prevent rupturing of the internal processing tank
due to an over pressure condition. If the internal pressure exceeds 300 psi, the valve will
open releasing the vapor side of the tank to maintain the internal pressure to below 300
psi.
WARNING! Do Not Plug or Restrict the Pressure Relief Valve at the top of the
machine. Damage to the Machine, Property Damage and Injury May
Result.
