Note: Before starting any maintenance observe the 'Safety information' in Section 1. 

6.1 General 

For maintenance of the individual components that make up the system, please see the relevant 

product specific IMIs for the components concerned. 

6.2 Scale formulation 

Within open systems, where there is continual make-up water, there is a risk of scale formation. The 

extent of the scale will depend largely upon the water quality, which varies greatly from area to area. 

A test, conducted by a water treatment specialist, is recommended to determine the local water quality 

and whether problems are foreseen. 

After extended service, the heat exchanger should be inspected for cleaning. If scale becomes a 

persistent problem, regular chemical cleaning should be considered.
