SPECIAL ASSEMBLY FOR INSTALLATIONS WITH A JETVAC: When
installing a JetVac attachment to a Little Still, the system is installed and assembled in a
way that allows the system to operate either with or without the JetVac. Use pipe tape on
all threaded connections to prevent vacuum leaks.
 Set the JetVac to the right of the Still, with approximately 24 inches of space between the units.
 Thread the discharge hose with sightglass into the JetVac’s distillate port (on the left side, towards the front of the
cabinet). Also thread the Y-strainer into the JetVac’s vacuum port (on the left side, centered).
 Thread a male quick-connect onto the JetVac’s metal braided hose female side. Thread a female quick-connect
into the discharge of the Still (on the right side, centered in the cabinet). Thread the metal braided hose into the
previously installed .
 Adjust the distance between the Still and JetVac until the metal braided hose quick-connects to the Still. Secure
the Still and JetVac to the floor once positioned.
 Attach the other male quick-connect to the Still’s discharge hose. This allows this discharge hose to attach
directly to the Still (after disconnecting the metal braided hose) for processing without the JetVac.
INSTALLATION OF THE FLAME ARRESTER TO JETVAC:
 The flame arrestor is designed to prevent flame from entering the distillation system through the vent pipe.
 Proper installation and location of the flame arrester is essential to effective operation.
 Installation must be inspected and approved by your insurance and/or fire inspector.
 Connection is made at the vent on the backside of the JetVac unit (see pg. 9 for location).
 The flame arrester must be piped so the arrow on the flame arrestor body points away from the distillation system
and must be connected to the end of the vent pipe.
 Using FTI supplied piping, screw the ½” nipple into the coupling on the back of the JetVac, attached a 90º elbow
to the nipple and a customer supplied connect a length of pipe to allow venting to a safe area (to the outside or
other safe area as determined by your insurance or other qualified inspector). Make sure that the piping is properly
supported and the flame arrestor is attached to the end of the vent pipe. Do not use pipe larger than ½” diameter.
 If venting unit to the outside, a gooseneck can be installed on the end of the flame arrestor to prevent rain from
entering the vent piping through the flame arrestor. The gooseneck must be ½” pipe, be installed at the end of the
flame arrestor and be no more that 5” long.
