5 Revision Date 8/28/2018 1. Critical Safety Overview Throughout these instructions, this symbol is used to indicate that the instructions are critically important to your safety and the safety of your system. Failure to follow the instructions as written can result in a rapid release of high pressure CO2 potentially causing equipment or personnel damage. WARNING Subcritical and Supercritical CO2 systems operate under high pressure. Operators must be fully trained and familiar with the system. Failure to operate the system can result in equipment damage and/or bodily injury. WARNING Subcritical and Supercritical CO2 systems use large amounts of CO2 during operation. Ensure that system is installed in a well-ventilated area to prevent buildup of CO2 which can cause asphyxiation. Use of a CO2 monitor is strongly recommended. WARNING Opening a vessel under pressure can result in a rapid release of pressure and ejection of the material inside the vessel. DO NOT ATTEMPT TO OPEN A VESSEL UNDER PRESSURE! Always make sure a vent path for the vessel is opened and the corresponding pressure gage reads zero prior to loosening the vessel hammer unions or closure bolts. WARNING Subcritical and Supercritical CO2 systems are designed to operate indoors. Extreme temperatures (below 60°F and above 80°F) will negatively impact the functionality of the system. The environmental temperature range is for the system, chiller, pump and CO2 bottles. WARNING Only use Propylene Glycol and distilled water in the chiller and cooling system. Never use Deionized Water in the chiller or cooling system. WARNING Always wear safety glasses when operating and servicing the system.

7 Revision Date 8/28/2018 2.1. The Duplex™ System Overview 2.1.1. Diaphragm Compressor – The diaphragm compressor for the Apeks 2000psi Duplex™ system is dual head compressor where both heads work in parallel to compress CO2 to the desired target pressure in the extractors. 2.1.1.1. Gauges on the Compressor 2.1.1.1.1. Oil Pressure Gauges – There are two gauges that display different oil pressures on the diaphragm compressor. The first is a high-pressure loop that incorporates the oil heat exchanger and some internal bearings. This gauge should read between 40-50 psi at all times when the system is running. The second is a low-pressure loop that incorporates the injection pump which supplies oil to the oil compression side of the diaphragm head. This gauge should read between 15-20 psi when the system is running. 2.1.1.1.2. Leak Detect Gauges – There is a leak detect switch on each pump head. This gauge monitors the cavity between the oil side and CO2 side to ensure that there is no crossover between the two systems. This gauge should display no pressure. See Troubleshooting section if this gauge shows pressure. 2.1.1.2. Pressure Switches 2.1.1.2.1. Oil Pressure Switch – The oil pressure switch monitors the low-pressure oil loop to make sure there is oil flowing in the system. If oil pressure is lost this switch will stop the system and an alarm will be triggered. 2.1.1.2.2. Leak Detect Pressure Switch – This pressure switch works the same as the leak detect gauge but continually monitors for the presence of pressure and will shut the machine down if over 15 psi of pressure detected in the pump cavity. 2.1.1.3. Over Pressure Valve (OPV) and Oil Bypass Valve – The OPV valve on the pump is a back-pressure regulator. The valve is set to allow the hydraulic oil pressure in the head to reach a certain point but not go above that point. The Bypass Valve is a needle valve with CO2 Outlet CO2 Inlet Junction Box Regenerative Heat Exchangers

8 Revision Date 8/28/2018 a black handle that can be opened in order to bypass the OPV. This is done during priming of the compressor and during head maintenance. (see appendix B) 2.1.1.4. Junction Box – The diaphragm compressor has a single junction box for the pressure switches that has a Harding Connector (electrical quick-connect) and thermocouples that go to the main control enclosure. 2.1.1.5. Regenerative Heat Exchangers – There are two regenerative heat exchangers that are located on the pump, one for each diaphragm head. These heat exchangers remove heat from the compressed CO2 to use on the separators. 2.1.2. Extraction Vessel Stand 2.1.2.1. Extraction Vessels – There are two extraction vessels on each stand. Vessel A is located on the right-hand side of the stand and Vessel B is located on the left. These vessels can be either 5L or 20L and are Hammer Union Closure vessels. This closer mechanism uses a nut to hold down a cap to allow the vessel to pressurize. Seals on this vessel are cup style seals which expand with the presence of pressure and create a face seal on the vessel. Extraction vessels are loaded and unloaded from the top of the vessel. When loading, unloading and cleaning these vessels be sure to keep face surface and threads clean. Failure to keep these surfaces clean can cause your vessel not to seal properly and could cause damage to your cup seal. 2.1.2.2. Locking Vessel Isolation Valves – Each extractor has two locking isolation valves that should be utilized whenever the operator is working in any vessel. These valves are Extractor A Extractor B Flow Switch Temperature Control Heat Exchanger

9 Revision Date 8/28/2018 intended to valve off the inlet and outlet of the vessel to protect the user from any release of pressure. WARNING: Failure to use these valves can lead to injury. 2.1.2.3. Temperature Control Heat Exchanger – The temperature control heat exchanger regulates the temperature of the CO2 just before it enters the extractor vessels and is in a cooling loop along with the extractor vessel water jackets and the extractor flow switch. 2.1.2.4. Extractor Flow Switch –The flow switch continually monitors for water flow in the extractor loop and will stop the system if flow is lost. 2.1.2.5. Vent Valves – Each extraction vessel has its own vent valve (Valve 4A and 4B) these valves will open automatically to vent the extractor so they are safe to open. These valves should be vented to the vent valve manifold (located on the Separator Stand) or outside. 2.1.2.6. Pressure Gauges – Three gauges, Extractor A, Extractor B and Pump outlet (located on top of temperature control heat exchanger), are located on the extractor stand and should correlate to the pressures on the HMI for each portion. 2.1.2.7. Junction Boxes – Each extraction vessel has its own junction box which will have a Harding Connector and at least one thermocouple connector that connects the main control panel. 2.1.3. Separation Vessel/Control Stand 2.1.3.1. Separation Vessels – The Separator stand holds four separators that work in banks of two. Bank 1 is located on the left-hand side of the stand and Bank 2 is located on the Bank 1 Bank 2 E-Stop Evacuation Valve Vent Valve Flow Switch Collection Cup Water Valves Cup Lift Control Panel Mount

10 Revision Date 8/28/2018 right. Each bank contains a main separator with an oil collection cup and a secondary separator with no cup. Users may use either set of separators at any time but only one set at a time. Separator banks that have identical gauges, filters and manual valving. 2.1.3.2. Main Control Enclosure/HMI – Unless otherwise stated at time of purchase, the separator stand will be where the main control enclosure and HMI (Human Machine Interface) are located. This enclosure contains the logic controller that operates the entire system. The HMI is located on the front of this enclosure and is where the user can monitor and control the system. 2.1.3.3. Motor Starter Box – The motor starter box is located on the back of the separator stand and houses the motor starter that controls the motor on the diaphragm compressor. 2.1.3.4. Air Valve Manifold – The Air valve manifold is located on the back of the separator stand directly behind the Main Control Enclosure. This manifold controls the air to each air actuated ball valve via red quarter inch airline. 2.1.3.5. Vent Manifold – This manifold collects all the vent lines to be vented outside by a single line. It is located on back, very top of the control panel mount and has a ½” discharge line up to 50 feet long. 2.1.3.6. Pressure Gauges – There are four pressure gauges located on the separator stand, two for each set of separators. The gauge located behind the main separator (psi range of 0- 2000) is the inlet pressure for the separator and should match the pressure of the extractors when the system is flowing. The second gauge is the pressure inside the separators and should match the separator pressure on the HMI. 2.1.3.7. Separator Filters – Each separator bank has its own separator filter. These filters should be inspected and cleaned between runs on the separator bank. See the preventive maintenance section 2.1.3.8. Locking Vessel Isolation Valves – Each separator bank has two locking isolation valves that should be utilized whenever the operator is working in any vessel. The bottle connections have an isolation valve as well. These valves are intended to valve off the inlet and outlet of the vessel bank to protect the user from any release of pressure. WARNING: Failure to use these valves can lead to injury. 2.1.3.9. Vent Valves – Each separator bank has its own vent valve (Valve 10) that can be use to release pressure from that bank of separators. These valves should be vented to the vent valve manifold located above the air valve manifold. 2.1.3.10. Evacuation Valves A and B – Each separator bank has its own evacuation valve that can be used to evacuate (draw a vacuum) the whole system before a run or evacuate the individual separator banks while running. See Manual Screen on the HMI to evacuate the entire system. 2.1.3.11. Separator Flow Switch – The flow switch continually monitors for water flow in the separator loop and will stop the system if flow is lost. 2.1.3.12. E-Stop Button – The E-Stop (Emergency Stop) Button can be depressed by the user at any time and will stop the system, turn off the pump, turns off the chillers and isolate every vessel. 2.1.3.13. Cup Lifts – There is a lift below each separator vessel to assist in the disassembly and the assembly of the separators and collection cups. This lift is air powered and actuated with the black toggle handle located to the right of the lift. Toggling the handle up will raise the cup lift and toggling the handle down will lower the cup lift. CAUTION: Use care to keep appendages away from pinch points when using the cup lift. 2.1.3.14. Cup Lift Regulator – This regulator is factory set but can be adjusted to increase or decrease the pressure to the cup lift piston.

11 Revision Date 8/28/2018 2.1.4. Bottle Connections 2.1.4.1. Main Supply and Recovery Bottles – Three 75lb Gas Supply CO2 bottles should be used as the main bottles for The Duplex™ system. These bottles are connected to the location shown above. 2.1.4.2. CO2 Make-Up Supply Bottle – One 50 to 75lb Gas Supply CO2 bottle should be used as a makeup bottle for CO2 lost during and at the end of each cycle. This bottle is connected to Valve 20 in the location shown above. 2.1.5. Extractor Chiller/Temperature Control Chiller – The Extractor Chiller is used to control the temperature of the CO2 before it passes over the raw material in the extraction vessel.

Before loading the extractor visually inspect the metal filters on either end of the vessel for any signs of clogs or damage. 3.1.1.4. Use the supplied metal funnel to help load the extraction vessel. Vessels should be loaded in stages using gentle packing in between to increase the amount of material able to be loaded into the vessel. 3.1.1.4.1. Typically, botanicals perform best in CO2 extractions when ground as fine as possible down to a particle size of 200 µin or roughly the consistency of coffee grounds. 3.1.1.4.2. Any amount of material can be loaded into the Extraction Vessel – the vessel does not have to be full in order to operate correctly. 3.1.1.5. After loading is complete, ensure all sealing surfaces are clean and free of debris. This includes the top of the extraction vessel, the cup seal groove, the threads and the face of the plug around the metal filter. 3.1.1.5.1. If threads need cleaning (e.g. get contaminated with raw material), remove all anti- seize lubricant from threads on both the vessel and the nut. 3.1.1.5.2. Once all old material is removed, reapply thin new layer of the food grade anti-seize. (acceptable anti-seize is included in initial system packaging and can be bought from the online store, see references) 3.1.1.6. Thread on the hammer union. Use supplied rubber mallet to fully close vessel 3 to 5 hits past hand tight. Both the nut and the vessel are marked with a closure mark (air etched line). These two lines should be no more than an eighth inch apart. Nuts should close to approximately the same location each time. If it does not then there may be debris in the threads that needs cleaned out. NOT CLOSED CLOSED
