Safety information, installation and maintenance

This document does not contain sufficient information to

install the product safely. See the Installation and Maintenance

Instructions provided with each unit.

Installation note:

Probes with tip lengths up to 500 mm can be installed vertically or

horizontally. Longer probes must be installed vertically.

The probe must be installed in a position where it can sense the

conductivity of the boiler water, away from the feedwater inlet if

possible.

Install the probe in a " BSP (1⁄2" NPT) female connection.

Note: Do not install the probe outdoors without additional

weather protection.

line of the boiler.

A maximum tip length

of 500 mm must be

adhered to on horizontal

applications.

Typical horizontal installation

on a boiler standpipe

using the longer 1000 mm

and 1500 mm probes.
