Section III - INSTALLATION

3.1 GENERAL

Examine the instrument for possible shipping

damages. IMPORTANT: If for any reason it is

determined that parts should be returned to the

factory, please notify the nearest Robertshaw

sales representative prior to shipment. Each unit

must be properly packaged to prevent damage.

Robertshaw assumes no responsibility for

equipment damaged in shipment due to improper

packaging.

Choose the location in accordance with good

instrument practice, avoiding extremes of

temperature, humidity and vibration (see

Specifications, Section II).

3.2 PROBE MOUNTING

Level-Tel probes for use with the Model 158A are

purchased separately from a variety of styles and

types which provide for various specific

applications involving liquids or granular

materials. Insulated rod-type probes are normally

used for liquid solutions or liquid-interface

junctions.

Since many materials have a tendency to build up

on the probe over extended periods of operation,

it is advisable on horizontally mounted probes to

place the probe so that its lower tip is below the

gland entrance. This encourages self-cleaning by

permitting the material to drip from the probe.

However, some materials will continue to build up

and cause the Level-Tel to become insensitive or

fail to operate. If such material is being used, the

installation should be made so that the probe is

easily removed for periodic cleaning.

The face of the gland on the rod-type probes

must be installed until nearly flush with the vessel

wall. DO NOT install the probe in a nozzle,

recess, or open-end well, unless the probe was

supplied with a factory assembled sheath as

there is danger of material collecting in such a

recess and causing false operation.

3.3 TRANSMITTER UNIT MOUNTING

The Model 158A is designed for vertical surface

mounting: e.g. wall, panel or column. Choose the

mounting location to avoid extremes of ambient

temperature or vibration (see Specifications,

Section II).

3.4 WATER TIGHT & WEATHERPROOF

TRANSMITTER MOUNTING & ELECTRICAL

CONNECTIONS

See Figures 1, 3, 4, 5, 6 and 7 for the mounting

dimensions and electrical connections of the

Water Tight and Weatherproof Transmitters. See

Figure 8 for interconnection diagram for those

models certified for intrinsically safe probe

installations.

3.5 EXPLOSION PROOF TRANSMITTER

MOUNTING & ELECTRICAL CONNECTIONS

See Figures 2, 3 and 5 for the mounting

dimensions and electrical connections of the

Explosion Proof Transmitter. See Figure 8 for the

interconnection diagram for those models certified

for intrinsically safe probe installations.
