Maintenance

6.2

Maintenance Preparation

Under regular operating conditions, the maintenance is limited to a semi-annual
inspection of the device. With increased load due to extreme operating conditions
(e.g. temperature, vibration, contamination, etc.), the inspection must be performed monthly.

Shut down the system control and secure it against inadvertent or accidental
restarting.

CAUTION!

Residual heat on all parts of the system and the ignition burner.
Risk of contact burns.

Allow the system and ignition burner to cool down before removal.
