POST PROCESSING WITH AUXILLARY PUMP AND LID
By using the Purge section of the control dial in
combination with and aux vacuum pump and lid (both
not included) you can post-process your extracts and
concentrate into any form you like. This is useful for
those trying to add stability to their end products or
getting to lowest possible level of residual ethanol.
The EtOH PRO can be used with an axillary (aux) pump assist (not included) by plugging the power cord
into the back of EtOH PRO and the vacuum line onto the empty spit jar port. The aux pump power switch
should be left in the ON position and EtOH PRO will turn the pump on and off as vacuum is required. Using
an aux pump will reduce pump down times and overall pump activity. The spit jar can eliminate much of the
liquid ethanol from entering the aux pump, but vapor may still contaminate the oil causing damage and
safety issues depending on the pump being used. If the chosen aux pump is not rated for solvent intake a cold
trap should be used. All manufacturer instructions and guidelines for pump safety must be followed to be
used along with EtOH PRO. It is also very important to remember if the vacuum pump is connected to
negative pressure end, you must use an in-line back-flow valve or check valve to avoid vacuum oil being
sucked out of the pump into the negative pressure lines, environments, and internal pumps.
