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 damage or harm to workers.
WARNING
Subcritical and Supercritical CO2systems operate under high pressure. Operators must be fully trained and
familiar with the systems. Failure to operate the systems correctly can result in equipment damage and/or bodily
injury.
WARNING
Subcritical and Supercritical CO2systems use large amounts of CO2during operation. Ensure that the system
is installed in a well-ventilated area to prevent buildup of CO2, which can cause asphyxiation. Always use a CO2
monitor to ensure safe operations.
WARNING
Opening a vessel under pressure can result in a rapid release of pressure and ejection of material from 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 gauge reads zero prior to loosening the vessel closure.
WARNING
Subcritical and Supercritical CO2systems are designed to operate indoors, in a temperature-controlled
environment. Extreme temperatures (below 60°F and above 80°F) will negatively impact the functionality of the
system. The environmental temperature range applies to the system, chiller, pump and CO2bottles.
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
Extraction system components can weigh in excess of 2000lbs and need to be moved carefully. Never attempt
to move system pieces without the proper equipment, failure to do so could result in serious injury or death.
WARNING
Always wear safety glasses when operating and servicing the system.

2.4. Facility Requirements
2.4.1. Temperature – The system is designed to run in a climate-controlled facility, where the
temperature is maintained between 60°F and 80°F.
2.4.2. Ventilation and Dust Control – The system should be placed in a well-ventilated environment
that is free from excess dust from other manufacturing operations.
2.4.3. Foundation – Apeks systems are designed to be installed on a concrete (or similarly stable) flat
floor.
2.4.4. Modulation – Apeks Duplex systems are designed to be able to be located in different rooms or
area to isolate different portion of the process. This modulation should be stated during the
purchase process or additional costs and delays may occur.
2.4.5. CO2Vent – Customer is responsible for running rigid tubing from system outlet to a safe vent
location. (NOTE: Vent lines should be rated to the pressure of the system. ⅜" x.035 or
½"x.049 stainless steel tubing recommended. Contact Apeks for part recommendation if
necessary.)
3. When the System Arrives
3.1. Receiving the Crates
3.1.1. Apeks Labeling – Look for an Apeks sticker on the outside of each crate to verify it came
directly from Apeks without tampering. See Figure 1. Note: If no sticker is found, open crate to
verify no damage has occurred during shipping.

Revision Date 04/11/2019
3.1.2. TiltWatch – Locate the TiltWatch Plus sensors on the outside of the crate, as shown in Figure
2. Ensure that the crate has not exceeded 30° in any direction. If the crate has exceeded 30°,
do not accept the delivery from the shipping company until contacting Apeks at [phone].
3.1.3. Inspecting Crates for Damage – Prior to opening the crate(s), verify that there is no external
damage. If damage is found, do not accept delivery from the shipping company without noting
any damage on Proof of Delivery. In addition, call Apeks at [phone] to report damage
and start the reporting process with the shipping company.

3.3.2.3.1. Once the water line connections and electrical connections have been made, fill the
chiller reservoir with 95/5 mix of water/propylene glycol.
3.3.2.3.2. From the manual screen, start the desired chiller.
3.3.2.3.3. Continue to fill the chiller reservoir with the same fluid mix as the chiller pump fills the
system with fluid.
3.3.2.3.4. Once the reservoir has stopped receding, top off reservoir and allow the chiller to
continue to run as the chiller pump primes.
3.3.2.3.5. This priming should continue until the pressure in the chiller reaches operational
level: 45psi for the extractor chiller, 78psi for the separator chiller. Note: if chiller over
pressurizes, partially close the ball valve on the back of the chiller to reduce pressure
to the operating pressure.
3.3.2.3.6. As the pressure increases the reservoir level may decrease so top off as necessary.
3.3.2.3.7. Once the chillers are up to pressure, the extractor chiller is ready to run and can be
turned off.
3.3.2.3.8. The separator chiller loop will need separator bank 2 filled with fluid
3.3.2.3.8.1. Go to the manual screen and click the “Fill Separator Bank 2 WATER” button.
Note: If this button does not appear on the screen click on the “Manual Mode”
button.
3.3.2.3.8.2. As the pump fills the second separator bank the reservoir will need to be filled
again and the pump may need to re-primed if the pressure drops.
3.3.3. CO2Connections – There are four CO2lines to be connected on the Duplex system, two
between the Extractor and Separator Stands and one each between those stands and the
Diaphragm Compressor.
3.3.3.1. Separator Vessel Stand to Diaphragm Compressor – This connection is a 36"long
stainless steel braided flexible line with ¾"compression fittings.

3.3.4. CO2Vent Connection – Apeks extraction systems come with rigid vent tubing all connected to
one outlet located near Valve 0 underneath the Motor Starter Enclosure. The customer is
responsible for running this vent line to desire location in build and should use material rated to
the pressure of the system (3/8"x.035 or ½ " x.049 stainless steel tubing recommended).
Connection is a 3/8"Swagelok compression fitting.
3.3.5. Air Connections – There are over twenty-five air operated ball valves that are used to control
the CO2flow path throughout the system. These valves are controlled by an air manifold on the
back of the control panel mount.
3.3.5.1. Air Manifold – The air manifold receives electrical signals from the controller and uses
compressed air to open valves. See Figure 12.

3.3.5.2. Separator Vessel Stand to Extractor Vessel Stand – There are thirteen ¼"red airlines
that run between the separator and extractor stand. These lines are connected with a
push-to-connect coupling and labeled on both sides. Fully insert the tubing into the
coupling to connect. See Figure 13.
3.3.5.3. Separator Vessel Stand to Diaphragm Compressor – There is one ¼" red airline that
runs between the separator stand and the diaphragm compressor. This line is connected
with a push-to-connect coupling and labeled on both sides. Fully insert the tubing into the
coupling to connect. See Figure 14.
