5.1.2 Mounting instructions

A bypass line can be shut off without interrupting the process. Sensors can be cleaned,

for example, without this adversely affecting the process. For this reason, installation in

the bypass is preferable to direct installation in the process line.

Shutoff valves must be provided by the customer.

1. Mount the product vertically.

2. Establish the medium connection with commercially available clamp fittings (8 mm).

3. If using a chlorine sensor:

Install a DN5-8 spigot downstream from the assembly outlet to take samples for a

reference measurement.

NOTICE

Medium pressure too high

Damaged or functionally impaired assemblies and sensors!

‣Observe the maximum permitted medium pressure for assemblies and sensors.

‣Do not exceed the maximum permitted pressure of 1.5 bar (21.8 psi).
