Section 1 - Components
Solvent Vessel
1.1.1. The Solvent Vessel contains the solvent, either LPG or ethanol, that dissolves the solute.
Material Columns
1.2.1. The solvent transfers from the Solvent Vessel into the Material Column and remains in the
Material Columns until reaching the desired soak time.
Dewax Column
1.3.1. The Dewaxing Column is used to separate the wax from the oil. The general steps are:
1.3.1.1. Solution is transferred into the Dewaxing Column from the Material Column.
1.3.1.2. Wax is precipitated from the soultion by chilling.
1.3.1.3. The dewaxed solution is transferred to the Collection Vessel.
Collection Vessel
1.4.1. The Collection Vessel receives the dewaxed solution. When using LPG as solvent, the solution is
boiled in the Collection Vessel, and solvent vapors are returned to the Solvent Vessel where
they are condensed back to a liquid. This recovered solvent can be used in the next extraction.

Section 2 - Getting Started
Review the following system installation and operation requirements information before preparing for
operation. Failure to do so may result in improper/unsafe installation and/or dangerous operating conditions.
System Placement
2.1.1. Place the system in a ventilated laboratory environment approved by the local fire marshal.
2.1.2. Place the system on a level surface.
Mounting of Components
2.2.1. Securely mount all vessels to the mounting rack.
2.2.2. Properly tighten mounting rack unions.
2.2.3. Level all components.
2.2.4. Lock all wheels on the mounting rack.
Chiller/Heater Options
2.3.1. For hazardous environments (Class I, Division 1 and Division 2 locations), both a liquid heat
source and cooling source will need to be plumbed into the hazardous area. Place the heater
and chiller in an area determined acceptable by the local building department.
2.3.2. UL listed equipment is typically required for this task. Submit a building plan to the local
municipality.
2.3.3. Speak to a Precision® Extraction Solutions technical representative to ensure the cooling and
heating options are adequate for seamless operation of the X40 MSE system in a passive
configuration. The X40 MSE extraction system comes pre-configured with heating and cooling
units suitable for this purpose.

Section 3 - Pressure Testing
The X40 MSE unit comes factory tested and inspected for sustained pressure holding capabilities. However,
shipping and moving of the unit may create pressure leaks and/or equipment exposure to drastic changes in
temperature. It is the operator's responsibility to check for pressure leaks prior to operation.
Checking the System for Leaks
3.1.1. Attach all the components and hose assemblies per
the drawing in this manual.
3.1.1.1. If pressure testing the entire new
system, include the Solvent Vessel.
3.1.1.2. If testing the system after filling the
Solvent Vessel, keep all valves on the
Solvent Vessel CLOSED. All remaining
valves should remain OPEN (excluding
valves leading to the atmosphere).
3.1.2. Attach a 1/4" MJIC hose to the Collection Vessel.
3.1.3. With all the valves open on the system (excluding
valves which leading to the atmosphere), bring the
system pressure to 150 psi, using compressed air via
an air compressor.
3.1.4. Open the vent down nipples on the gauge prior to
performing a pressure test.
3.1.5. Note the actual readings of the pressure gauge by
taking a photo for later comparison.
3.1.6. For a primary pressure test (first test), allow the
system to sit at 150 PSI for at least 24 hours. For a
secondary pressure test (any test performed after
the primary pressure test), allow the system to sit at 150 PSI for 1 hour.
3.1.7. Note any changes in pressure. Significant decreases in pressure indicate a leak, and the unit is
unsafe to operate.
Identifying Leak Locations
3.2.1. Identify leaks by filling a spray bottle with soapy water and spraying the area of the unit where
the suspected leak is located. The presence of bubbles confirms a leak.
3.2.2. The most common areas for leaks are the valve seats (which could need to be re-taped) and the
sight glass (which may need to be re-tightened).
3.2.3. Before adjusting/tightening/re-taping any pieces on the unit, vent the system down to 0 psi.
3.2.4. Once the unit passes a pressure test, the Solvent Vessel is ready to be charged/filled.

Other Necessary Procedures and Notes
3.3.1. Inspect equipment cleanliness. Precision keeps equipment as clean as possible following
production; however, shipping and handling of the equipment
can cause contamination. It is the responsibility of the user to
ensure all surfaces are always clean and sanitary.
3.3.2. To clean the system perform a “wet run” with solvent, but
without material. Clean the Solvent Vessel with special
attention. Vacuum the Solvent Vessel with the hose by removing
the center tri-clamp fitting.
3.3.3. If using ONE chiller to cool MULTIPLE columns, use “T” joints to
split the feed and return lines to service both columns. Use TPE
hosing for these lines.
NOTE—It may be necessary to purchase extra lengths from a
hardware store to place the heater and chiller in the most
desirable spots for setup. Insulation on the lines AND the
columns is essential.
3.3.4. Once the heater and chiller are in place and the equipment is
free of leaks, the user must insulate all the chilled lines and
columns.
3.3.5. It is most desirable to use ½” quick release fittings for the
collection bowl. These fittings are available from Precision®
Extraction Solutions and make disconnecting the heat bath lines
much easier.
3.3.6. It is essential to insulate the lines and columns that connect to the
chiller. The better they are insulated, the more efficient the
machine and chiller will function.
3.3.7. It is highly recommended to purchase a stainless-steel insulated
hose kit from Precision® Extraction Solutions for the heaters and
chillers.

Section 4 - Charging/Filling Solvent Vessel with Hydrocarbon Solvent
Use the following procedure for charging/filling the Solvent Vessel. Common issues and solutions are included
after the procedure description. Always disconnect the vacuum pump prior to introducing solvent.
Procedure for Charging/Filling the Solvent Vessel
4.1.1. Wheel the solvent tank onto the scale.
4.1.2. Fill the Solvent Vessel with no more than 120 LBS of hydrocarbon or
100L of ethanol for the X40 MSE model. It should appear through the
sight glass to be about 75–80% full.
4.1.3. Attach the solvent source to the X40 MSE Solvent Vessel via a 1/4" FJIC
Line.
4.1.4. Verify the fittings are correct to safely attach the source vessel to the
X40 MSE Solvent Vessel. These fittings vary by supplier. Check with the
hydrocarbon solvent supplier to procure the proper fittings.
4.1.5. To charge the X40 MSE Solvent Vessel, begin by vacuuming the vessel
down to -30 inHg or until the vacuum pump bottoms out. Ensure the
line from the X40 MSE Solvent Vessel to the solvent source vessel is
under a vacuum.
4.1.6. Cool the Solvent Vessel.
NOTE—If using a Precision chiller, turn on the chiller and allow the vessel
to cool. Depending on atmospheric conditions, the solvent source vessel
may need warming. This can be done by placing the vessel in a hot water bath.
4.1.7. Fill the X40 MSE Solvent Vessel with it detached from the mounting rack, while sitting on a
refrigerant scale.
4.1.8. Start with all valves closed, then open the valve on the X40 MSE
Solvent Vessel leading to the solvent source.
4.1.8.1. Open the valve on the solvent source vessel.
4.1.8.2. Note the flow rate into the X40 MSE Solvent Vessel.
4.1.8.3. For the initial fill of the system, use a refrigerant scale.

Section 5 - Preparing for Operation
Prior to use, the operator must read and be familiar with the specific operation manual of the recovery
equipment (e.g., pump/compressor operational manuals). The following procedure outlines the steps for
preparing for passive and active operation. Tighten all connections with an adjustable wrench before
proceeding.
NOTE—For active recovery using either a Precision GC 5000 pump or other recovery equipment, adhere to the
following procedure.
Initial Preparation
5.1.1. Verify the Material Column matches the weight and volume of the
material to be processed.
5.1.2. Ensure the Material Column mounts properly to the mounting rack.
5.1.3. Fill the Material Column with the material to be processed. Leave about 1-
2 inches of headspace at the top of the column. The packing density of the
material is at the operator's discretion.
5.1.4. Attach the Material Column cap to the top of column.
NOTE—For new users to a closed loop system, the manufacturer
recommends the operator bypass the Dewaxing Column until more
familiar with the X40 system.
5.1.5. At the operator's discretion, fill the Expansion Column with a blend of 3A
and 4A molecular sieves. Molecular seives can be purchased from Delta
Adsorbents. Precision recommends changing dessicant every 10 runs. The
lifespan of dessicant is dependant on the moisture content of the material
being extracted
5.1.6. Begin operating the recirculating chiller.
5.1.7. Cool the Solvent Vessel to the desired temperature via the chiller.
NOTE—Cooling the Solvent Vessel reduces the vapor pressure of the
solvent. This will reduce the amount of solvent that can be passively
transferred into the material column.
5.1.8. If using the Dewaxing Column, cool it via the chiller. It takes approximately
45– 60 minutes for the Dewaxing Column to reach the acceptable
temperature range (-30° C) – (-50° C).
5.1.9. The chiller should be operating at the desired solvent temperature continuously. This minimizes
system downtime and allows for the storage of solvent in the Solvent Vessel overnight.

5.1.10. As the Solvent Vessel and Dewaxing Column cool, vacuum all remaining
columns and hoses. Attach the vacuum pump to the Collection Vessel and
open the proper valves. Vacuum the system until the pump "bottoms
out" or until reaching approximately -30 inHg.
5.1.11. To comply with Class 1, Division 1 or Class 1, Division 2 standards,
applications in hazardous environments can route the vacuum line outside
the classified room.
5.1.12. With the Solvent Vessel and Dewaxing Column chilled and the system
under a full vacuum, the system is now ready to run.
Preparing for PASSIVE Operation
5.2.1. Connect a hose from the ball valve at the bottom of the Expansion Column
to the inlet side of the condenser coil. The inlet side of the coil leads
to the bottom of the condenser coil first. The return hose is a ¾”
MJIC fitting on one end and a ¾” compression fitting on the other
end.
5.2.2. Connect a hose from the outlet side of the condenser coil to the
return valve on the Solvent Vessel. The return valve is located on the
collar of the Solvent Vessel in the left, rear position. This section of
the return line will be a MJIC fitting on both ends.
Preparing for ACTIVE Operation
5.3.1. Connect the active recovery pump to the closed loop system:
5.3.1.1. Connect the hose from the outlet valve on the Expansion
Column to the inlet side of the active recovery pump. In
most cases, this hose is a ¾” compression fitting on one
end and a ¾” MJIC fitting on the other end.
5.3.1.2. Connect the hose from the outlet of the active recovery pump to the inlet on the
condenser coil. The inlet of the condenser coil is the line that goes to the bottom of
the coil.
5.3.1.3. Connect a hose from the outlet on the condenser coil to the return valve on the
Solvent Vessel. The return valve is located on the collar of the solvent in the rear,
left position.
5.3.2. Turn on the heater attached to the Collection Vessel and Expansion Column.

Section 6 - Running the Extractor (Hydrocarbon)
The procedure for connecting the X40 system to a GC
5000 Recovery Pump for active recovery is provided in
Section 2 of this manual. The operator of such
equipment must read and be familiar with the specific
operational manual of the recovery equipment prior to
use (e.g., pump/compressor operation manuals).
If the user is new to using a closed loop system,
Precision recommends that the user bypass the
Dewaxing Column until the user becomes more familiar
with the X40 system. Dewaxing is not always necessary
and may be counterproductive to the user’s specific
desired product types.
Keep the Solvent Vessel as cold as possible during the
recovery process. This helps condense the solvent as it returns to the Solvent Vessel.
Use the following procedure to begin operating the extractor using hydrocarbon
solvents.
Pressurize Solvent Vessel
6.1.1. All ball valves on the system should now be in the CLOSED position.
6.1.2. Attach hose from nitrogen regulator to the ¼” MJIC vapor valve on the
Solvent Vessel.
6.1.3. Set the regulator to 30 psi above the desired pressure.
6.1.4. Open the vapor valve on the Solvent Vessel.
6.1.5. Allow pressure to reach desired level.
6.1.6. Close vapor valve.
Transfer Solvent to Material Columns
6.2.1. Open the siphon tube valve on the Solvent Vessel - this valve leads to the
manifold on the left side of the Material Column stand.
6.2.2. Open the large ball valve on the solvent manifold - this manifold is located along the left side of
the Material Column stand.
6.2.3. Fill Material Column 1 by opening valve 1 on the manifold. Solvent
begins to flow into the Material Column. Allow solvent to flood the
Material Column. The Material Column is full when the pressure in the
column is within a few psi of the Solvent Vessel pressure.
6.2.4. Close valve 1 on the solvent manifold.
6.2.5. If necessary, re-pressurize the Solvent Vessel headspace with nitrogen to
fill the second column—refer to 6.1.
6.2.6. Fill Material Column 2 by opening valve 2 on the manifold. Solvent
begins to flow into the Material Column. Allow solvent to flood the
Material Column. The Material Column is full when the pressure in the
column is within a few psi of the Solvent Vessel pressure.
6.2.7. Close valve 2 on the solvent manifold.
