II. SETUP INSTRUCTIONS
1. Position the control unit in the desired location.
Position the remote valve box within two feet of the
experimental site (VELCRO® is supplied for
mounting) and within 6 feet of the control unit.
2. Connect the black ¼ inch pressure tubing to the
side port on the front panel regulator and to a
source of clean dry compressed gas (air, nitrogen,
CO2, or argon) at a maximum of 150 PSI (10bar).
DO NOT USE OXYGEN OR COMBUSTIBLE
GASES.
The fitting on the regulator is a quick-
connect type. The end of the tubing should be cut
cleanly and inserted fully into the opening in the
fitting. An o-ring seals around the outside of the
tube. To remove the tubing from the fitting you
must first vent the pressure from the line then press
the ring on the end of the fitting (around the tubing)
toward the body of the fitting while pulling on the
tubing.
3. Use the 6-foot long 1/8-inch tubing assembly to
connect the front panel regulator to the remote
valve box. The connection at the regulator is also a
quick-connect type while that to the remote valve
box is threaded (1/4-28 male). There should be a
ferrule pressed in to this end of the tubing.
4. The 3-foot long 1/16-inch tubing assembly is
used to connect the remote valve box to a pipette
holder (optional). Both ends of this assembly have
¼-28 nuts and ferrules pre-assembled on it.
PLEASE NOTE:
An important detail in arranging
the location of the solenoid in relation to the pipette
holder is to maintain a loose coil in the
interconnecting small bore (1/16 inch) Teflon®
tubing to absorb or dampen the pressure pulse, thus
avoiding movement of the pressure pipette. DO
NOT stretch the tubing out tight between the valve
housing and the pipette holder.

III. CONTROLS AND USE
The unit is activated when the power switch is in the
ON position and the red pilot light is on. The unit
must be connected to a source of clean, dry
compressed gas at a pressure at least as high as that
desired for ejections. Clockwise rotation of the
knurled knob on the right of the rack mount panel
will increase the pressure (indicated on adjacent
gauge) available for injection purposes. This unit
contains a self-bleeding regulator so that the pressure
may be reduced by simply rotating the pressure
control knob counter-clockwise.
