1.3 Before You Begin
1.3.1 Site Preparation
Each Kotron Model 822, 832 and 842 switch is built to
match the specific physical specifications of the required
installation. Make sure the probe connection is correct for
the threaded or flanged mounting on the vessel or tank
where the switch will be placed. See Section 1.4, Mounting.
Make sure that the wiring between the power supply and
the Model 822, 832 or 842 switch is complete and
correct for the type of installation. See Section 3.2,
Specifications.
When installing the Model 822, 832 or 842 switch in a
general purpose or hazardous area, all local, state, and
federal regulations and guidelines must be observed. See
Section 1.7, Wiring.
1.3.2 Equipment and Tools
No special equipment or tools are required to install
the Model 822, 832 or 842 switch. The following items
are recommended:
• 1¹â„8" open-end wrench or adjustable wrench to fit the
probe process connection size and type.
• Flat-blade screwdriver
1.3.3 Operational Considerations
The Model 822, 832 or 842 switch should be located for
easy access for service, configuration, and monitoring.
There should be sufficient headroom to allow the probe
to be inserted into the tank. Special precautions should
be made to prevent exposure to corrosive atmosphere,
excessive vibration, shock, or physical damage.
The electronics should not be exposed to ambient temper-
atures above +160° F (+70° C) or below -40° F (-40° C).
The proper operating temperature range for the display is
-4° F (-20° C) to +160° F (+70° C). The temperature
limits for the probe depend on the style and part number
of the specific probe used.
