TEST Chemtech 1 + 2 Terpene Cleanse PM (Monthly)
Once a month, run a carboy of collected terpenes through the Chemtech 2 to remove residue that isn't easily soluble in water or ethanol. This cleaning is essential to maintain proper separation in distillation in order to get a light color. Perform an ethanol/water/ethanol cleaning as usual, run the terpenes, finish with another ethanol/water/ethanol cleaning.
Use ethanol rinse parameters for the terpenes.

Continue distilling until all the feed material has been distilled. Insert stopper into inlet of the pump at the bottom of the feed vessel. ( ** If the feed reservoir becomes empty without inserting the stopper, vacuum will be broken, and the vacuum pump can be damaged. ( To prevent vacuum loss, monitor the feed oil level until it gets to the bottom, then as the last of the oil drains into the feed pump, If vacuum begins to suck air into the pump inlet, simply insert the stopper to prevent total vacuum lo
Once feed vessel has been plugged continue distilling for approx. 15 mins to allow material in feed transfer and evap column to fully discharge. Once fully discharged ensure Eco Pump transfering to ChemTech 2 is run for an additional 5 minutes to all material in transfer to drain to ChemTech as much as possible. Some material will still be present in transfer line. Once transfer is complete stop Eco Pump via control box and lower temp on Feed/Residue heating bath to 45°C. Allow feed bath to cool before proc
Once temperature of transfer line has dropped to set point place collection container under transfer bleed fitting. Using causing remove transfer bleed fitting and allow transfer line to full drain.
Once transfer line has fully discharged return fitting into position. Tighten fitting to maintain seal but note overtightening will shorten the life of fitting.
If the bell jars need to be emptied, the normal shutdown procedure must first be executed. (See Section 7.5. Shut Down) (**Never attempt to remove the glass discharge vessels when the system is under vacuum.**)

Water/EtOH Cleaning Procedure
Follow this procedure for visual validation checks
Set Equipment to these conditions
Close both of the right-angle valves to isolate the turbo pump and the rotary vane vacuum pump from the rest of the system.
Remove the vacuum sensor and needle valve from the system before performing the cleaning cycle.
First Pass - Clean the entirety of the feed tank using the water:ethanol mix 10:90. Water should be either RO or distilled. Minimum of 500ml must be used.
Verify Equipment set points - Feed Rate: 50 Wiper Speed: 250 Feed/Residue: 50°C Evaporator: 78°C Condenser: 50°C Cold Trap: 5°C
Allow water:ethanol mix to reach set point temp then run the feed pump at a rate of 50 to remove all contaminated water/ethanol. Empty cold trap collection as needed as to not allow to over fill.
Prepare for Second Pass-Set Equipment to these conditions
Second Pass- Use 500 mL of the water. Empty cold trap collection throughout process as need as to not over fill.
Prepare for Third Pass-Set Equipment to these conditions
Third Pass- Use a minimal of 250 mL of the ethanol. Empty cold trap collection throughout process as need as to not over fill.
With discharge pump systems – once all fluid has passed through discharge pumps turn controllers to the stop position and power off.
If additional cleaning is needed, then repeat the water/ethanol cleaning cycle as many times as needed until the distillate and residue streams are flowing clean and clear ethanol/water.
**If system is equipped with discharge pumps.** This step is to maintain lubrication in gear pumps.
1.) Fill 50ml conical falcon tube can be filled with terp strip material. 2.) With the vacuum bleed port open set the discharge pump controllers to ‘reverse’ and a slow rate of 10 or less. 3.) Place the conical falcon tube at the base of one of the check valves at the exit port of the discharge pump and raise enough to submerge the tip into terp strip material. 4.) Turn on the discharge pump controller to back feed terp strip material until material is seen int the sight glass. Stop the pump via the pump controller. 5.) Switch direction from ‘reverse’ to ‘forward’ and start the pump again discharging material back into the conical falcon tube. Run until no material is seen dripping and stop pump via controller and power pump down. This will keep the gear pump lubricated and prevent excessive wear. 6.) Repeat steps 7.6.10 for other discharge pump if necessary. NOTE: The next time the system is started up for a THC distillate pass, 1-3 cups will need to be collected from the distillate side of the discharge pump and redeposited into the feed tank. This will remove any of the terp strip used as lubrication.
Drying
Set Equipment to these conditions
The system is in hot state with no feed at the set conditions above.
After allowing the warmer temperatures to dry the system at atmosphere for 1 hour, return vacuum gauge and needle valve bleed port to proper position closing the needle valve bleed port.
Open the main vacuum isolation valve and pull vacuum using only the main rotary vane vacuum pump for 1 hour to fully dry the system out. Keep the turbo pump isolated (closed) from the system for the vacuum drying portion. Change the vacuum pump oil after finishing the drying process.
