5. Installation
Control Panel and Electrodes preferably should be mounted close to one another as possible and
no greater than 50 feet apart (See Fig. 1).
5.1 Control
Panel
5.1.1 Mounting and Location
Mount the Instrument Control Panel on a secure stand, bracket, or wall by the mounting feet
provided. Location of the control panel should be determined according to process layout,
keeping in mind that it is preferable to locate the control panel in a dry environment, whenever
possible, even though it is rated for wet environments at NEMA 4X.
The control panel should be accessible for routine maintenance and easy viewing of the front
digital display, as well as the Visual Alarm, and in hearing range of the 80 db Audio Alarm (See
Fig. 3). It should also be located with enough space underneath of at least two feet for mounting
the Injection manifold, along with the switches and cables.
5.1.2 Electrical and Power
The control panel requires
110VAC at 15 Amps
. The panel is supplied with a 3-prong grounded
plug. Extra attached loads such as valves, mixers, and other such devices should be included in
the total electrical requirements.
WARNING:
To reduce the risk of electrical shock, the control panel must be plugged into a
grounded outlet with ratings conforming to the requirements to the control panel, and any other
electrical loads connected to it. The panel should be connected to a good ground.
DO NOT USE ADAPTERS!
All wiring must conform to local electrical codes.

Terminal strip locations 1-4 are used to power the pumps. Terminal strip locations 5-6 are used
for flow / pressure switch. Terminal strip locations 7-12 are used for recording.
(If not used for
recording, please do not remove the jumpers.)
Terminal strip locations 13-16 are 4-20mA output
signals to control proportional pumps.
