MAINTENANCE
17.1
General
For a good, safe and long-time operation of the water heater, it is advised to carry out maintenance and service at
least every twelve months. Both safety and life time will thus be improved. Omission of preventive and corrective
maintenance can have warranty consequences.
Maintenance and inspection of the water heater should be carried out at the following occasions:
•
When a number of similar error codes and/or lock-outs appear.
•
At least every twelve months maintenance must be done to ensure safe and efficient operation.
Damage caused by lack of maintenance will not be covered under warranty.
MAINTENANCE REMINDER FUNCTION.
See last 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 twelve 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 section 10.15 ‘Setting the maintenance specifications’ on
page 70.
Service intervals
The normal service interval for the water heater is once a year. Every year the water heater should be cleaned
and checked, according to the maintenance procedures. If there is doubt whether the water heater 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 to determine the frequency of the future service intervals. The maximum interval between two services
can be a year.
INSPECTION AND MAINTENANCE MUST BE EXECUTED FOR A SAFE AND EFFICIENT OPERA-
TION OF THE WATER HEATER.
