MAINTENANCE REMINDER FUNCTION.
See previous page
.
BE AWARE: This function is standard turned off. We offer this programmable function to the installer to use as a
reminder. Because it concerns a free programmable function the use of it cannot be used as an argument in warranty
cases. Our units must be maintained every 12 months whatever the settings/working of this function.
It is and remains the responsibly of the end user to have the unit maintained every twelve months.
For more information about this maintenance mode see chapter 10.14,
‘Setting the maintenance specifications’.
Service intervals
The normal service frequency for the boiler is once a year. Every year the boiler should be cleaned and checked,
according to the maintenance procedures. If there is doubt whether the boiler is operating with the correct water
and/or combustion air quality, it is advised that a first check is executed after already half a year. This check serves
to determine the frequency of the future services. The maximum interval between two services is a year.
INSPECTION AND MAINTENANCE MUST BE EXECUTED FOR A SAFE AND EFFICIENT OPERATION
OF THE BOILER.
