Installation
Installation considerations
• Do the mechanical installation tasks first, the electrical installation tasks second, and the plumbing
installation tasks last.
• All fittings are designed to be tightened by hand only.
• The panel is designed to be wall or rack mounted. Mount or position the panel in an accessible
location.
• Do not place the panel next to a heat source.
• Do not mount the panel in an environment with frequent vibrations
• Do not mount the panel in direct sunlight.
• Install the panel indoors or in an environmental enclosure.
• Prevent condensation from collecting on the panel and panel components, especially the flow cell,
sensor and where the sensor and cable connect.
• Use Teflon
®
or PVDF linear low-density polyethylene tubing for the sample supply line and keep
the tubing as short as possible to minimize lag time.
• Sample pressure must be sufficient to keep a continuous water supply to the sensors. An LED
indicator on the flow sensor will be lit as long as the flow is sufficient.
• Keep the flow rate as constant as possible for best sensor operation.
Sample line guidelines
Select a good, representative sampling point for the best instrument performance. The sample must
be representative of the entire system.
To prevent erratic readings:
• Collect samples from locations that are sufficiently distant from points of chemical additions to the
process stream.
• Make sure that the samples are sufficiently mixed.
