Maintenance
Depending on the operation conditions the units are to
be tested by an expert when necessary, but at least
regularly every two years, to ensure their safe operation.
The test result is to be recorded in a test certificate
which is to be safely kept until the next test so that it can
be presented to the authorised persons for control pur-
poses at any time.
Regular maintenance and care, at least after each heat-
ing period is the basic condition for a long service life
and a faultless operation of the unit.
Setting and maintenance is to be carried out only
by authorised experts!
