10 Maintenance
10.1 General
10.1.1 General instructions
In heating and air conditioning systems, a regular inspection and mainte
nance as required by qualified personnel contribute to correct operation
according to the product specification, and therefore to ensuring high effi
ciency and low environmental pollution in the long term.
Danger of electric shock
Before any work, switch off the mains supply to the boiler.
Before removing parts of the casing, the boiler has to be de-ener
gised.
Work under voltage (removed casing) may only be carried out by
a trained electrician.
Caution
Only a qualified professional is authorised to clean the inside of
the boiler.
