JETVAC ATTACHMENT:
CAUTION:
Do not process solvents with boiling points below 200º F with the JetVac. Release of hazardous vapors and
damage to the equipment may result.
1. Lift the top panel of the JetVac’s cabinet and prop it open with the supplied prop bar (attached under the top
panel). If changing the solvent or cleaning the reservoir, the “old” solvent can be drained through a ball-valve
located on the right side of the JetVac’s cabinet.
2. Locate the pump reservoir, unscrew the two wing-nuts, lift the reservoir lid, and set the lid to the side.
3. Fill the pump reservoir with clean solvent (the same type of solvent that is being processed). Ground all transfer
equipment, containers, and personnel (see Safety Precautions). Replace and secure the pump reservoir’s lid.
4. Start the system by turning on the Still (and pulling the STOP/START switch of the JetVac to the START
position). Allow the JetVac to generate vacuum (as indicated on the vacuum gage). When the vacuum level no
longer rises, use the vacuum adjust valve to adjust to desired vacuum level, then close the top panel.
5. IMPORTANT: On new installations, it may be necessary to tape the Still’s lid with the supplied pipe tape for
the first few runs, or until the Still’s lid gasket compresses and seals properly.
6. At the end of the process, the JetVac will shut down automatically (when wired in the automatic mode). In
automatic mode, the STOP/START switch can remain in the START position, and operation will be controlled
by the Still. When the JetVac stops, the vacuum will be relieved through a vacuum relief solenoid (atmospheric
vent).
NOTE: For processing atmospherically (without vacuum) with a JetVac attached to the Still, simply push the
JetVac’s STOP/START switch to the STOP position, disconnect the metal braided hose at the Still with the quick-
connector, connect the Still’s red discharge hose to the discharge of the Still, and place the grounded receiving drum
under the Still’s discharge hose. Follow the operation instructions for the Still.
