3.0 INSTALLATION
3.1 Location
3.1.1 Install the instrument within 3000 feet of where the AquaMetrix differential probe
(R60 Series) is installed. If a conventional combination probe (R500 Series) is used
the instrument must be within 25 feet of the probe for direct connection. An
AquaMetrix 101 Series preamplifier may be used to extend this distance to 3000
feet.
3.1.2 Select an installation site which is:
• free of mechanical vibrations
• reasonably clean and dry
• protected from falling corrosive fluids within the ambient temperature and humidity
specifications
• remote from high voltage relay and power switches
3.2 Type of Mounting
3.2.1 If the instrument is to be pipe or panel mounted a special hardware kit will be
required. For panel mount order part number C35-68. For pipe mount order part
number C35-69. Instructions for both types of mounting will be included with the
kits.
3.2.2 For surface mounting, four feet brackets, together with fastening screws, are
provided with the instrument. These should be fastened to the back of the
instrument and then it may be screwed or bolted in the selected location.
3.3 Conduit Connections
3.3.1 Four 1/2" conduit holes are provided in the bottom of the enclosure. One of these is
fitted with an approved water tight plug. To maintain NEMA 4X integrity, approved
conduit hubs must be used to connect conduit. The hubs must be connected to the
conduit before being connected to the enclosure. Any unused conduit holes must
be closed with water tight plugs or connectors.
3.3.2 For convenience of internal connections the right conduit hole (viewed from the
front) should be used for power connection; the next hole to the left for relay
outputs; the next hole to the left for analog outputs and finally the fourth hole for
sensor input.
