Installation

As with all instrumentation, the installation and commissioning of this instrument are crucial to its 
safe and effective operation. This instrument must only be used for its purpose as outlined in this 

 

manual. It must be installed and commissioned by this manual and by trained, qualified personnel.

Site Selection

Please choose a suitable location for the installation of the electronics. The choice of installation 
point on any site is a compromise and is best undertaken by an experienced installation engineer. 
The following is a list of the factors that need to be taken into consideration. 

• 

Ensure that the mounting allows access to all serviceable parts.

• 

Try to mount the electronics in a position where they are not habitually hosed down in a 

 

cleaning process.

• 

The electronics enclosure should be mounted away from sources of heat or direct sunlight.

• 

Consider the length of wiring runs when mounting the instrument.

• 

Try to keep the electronics away from substations, motors or other large EMI emitters.

• 

Consider whether the sample will be representative and well mixed.

• 

Consider sample line run times.

• 

Consider sample return points.

• 

In a plastic run, with a low conductivity liquid sample, consider earthing the sample.

• 

If the instrument is controlling a dosing pump, size the pump appropriately.

Note: 

This list is not intended as a checklist neither is it implied that the list is complete.

 

Unpacking

• 

Please have a copy of your order with you when you unpack your instrument. 

 

All orders are checked when they leave the factory. 

• 

Please check that you have all the parts that were ordered as soon as you open the box.

• 

If anything is missing or damaged, please contact your sales outlet immediately. 

• 

If the instrument needs to be returned for any reason please follow the return instructions given 
in this manual.

• 

Please dispose of the packing in an environmentally responsible manner and  in compliance with 
local regulations.
