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:

•11⁄8" 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.
