Control Form Function Air On/Off Manual Valve In the closed position, air supply is shut off to the ZEVAC – shutting down the machine. Air Pressure Regulator Manual Adjustment Raise or lower the maximum air pressure delivered to the ZEVAC.
Page 6 Discharge Pressure Automatic Interlock In the event that the discharge Shutoff pressure exceeds the set point, this control valve will prevent the ZEVAC from continuing to actuate. Suction Pressure Automatic Interlock In the event that the gas suction Shutoff...
Page 7: Check Before Operation
Air supply is connected to ZEVAC in a secure fashion Air supply connection piping / hoses have been verified to be leak-free Air regulator is set to deliver adequate pressure to ZEVAC (100 – 250 psi) VERIFY Hose halters are in place on all hose connections...
Page 8: Startup
STARTUP Pre-Startup Purge (First Startup) In order to avoid the mixture of air and flammable gases, it is required to purge the ZEVAC® of air before introducing other gasses. Purging can be accomplished with inert nitrogen. The procedure for performing this purge is listed here: Step Check Description Connect an inert gas such as Nitrogen to the Gas Intake piping (“Tree”)

• Verify the drawdown system is isolated. If the drawdown system is open to any source of flow, the ZEVAC will not be able to reduce the system pressure. This can occur in the case of a valve leaking past its seats while in the closed position. As the ZEVAC is evacuating gas, the valve is allowing gas to enter the drawdown system and the pressure may not drop or may reduce more slowly than normal.
Page 14 • It is common for air compressors to introduce moisture to the air supply. There is equipment on the ZEVAC® that is designed to eliminate as much of this water as possible, but it is common in certain operating conditions such as high humidity for water vapor, mist, and liquids to be present in the air system.
Page 15 4. Always maintain clear access to the air compressor supply air to the device. In the event that the ZEVAC unit cannot be accessed and needs to be shut down, turn off the air supply. 5. Always turn off the unit when making adjustments or changing connections.
