3.0 Pumping Instructions
3.1 Preparation
• The Control Unit is shipped without the batteries in the housing.
Install these before operating the unit. The Control Unit uses four
(4) AA alkaline batteries.
• Do not let water get inside the Control Unit. Always position the
Control Unit physically higher than the sample discharge and
wellhead. This helps avoid the siphoning effect, where gravity back-
flow of sample water can enter the Control Unit and cause damage.
• Do not release any pressure from the compressed gas supply until all
preparatory steps are complete.

3.2 Pumping Set Up
1. Connect the Supply Line to the Air In fitting on the Control Unit. Attach the
other end to the compressed gas supply source.
2. Ensure your pump is installed to the desired pumping depth with the sample
and drive tubing properly connected.
3. Connect the Drive Line from the Air Out fitting to the quick connect on
the wellhead manifold (or air supply connection on a reel). The Drive Line
supplied, with the Quick Exhaust fitting, should always be used.
4. Press any button on the keypad to turn the Control Unit on.
5. Select the desired pumping settings.
6. Set the compressed gas supply regulator to no more than 150 psi for the
125 psi Control Unit, or 300 psi for the 250 psi Control Unit.
7. Start the selected drive/vent cycle.
8. Allow several cycles for water to reach the surface, then adjust the settings
as necessary.

NOTE
Always follow local health and
safety practices. Work safely!
NOTE
Keep Control Unit physically higher
than the sample discharge and
wellhead.
NOTE
While the drive/vent cycles are in
progress it is not possible to edit the
displayed site information or exit
the site menu when using a Saved
Setting.
NOTE
The Pressure Regulator on the
Control Unit may hiss during
operation; this is normal.
NOTE
You should always use the Drive
Line supplied with the Control
Unit, as it uses the Quick Exhaust
fitting, which is required for proper
operation.
NOTE
When using a Solinst 12 Volt
Compressor, or any other air
compressor, it is recommended
to use the 464 External Filter. See
Section 4 for more details.
NOTE
The Control Unit will turn off after
five minutes of being idle, provided
the Unit is not cycling. To turn the
Unit off, hold down the OK button
for at least 3 seconds.
