10.3 Maintenance work
10.3.1 Visual checks

DANGER!
Risk of injury from burning
The electronics housing of the EC fan reaches high temperatures. Avoid direct contact!
IMPORTANT NOTE!
Do not use aggressive cleaning agents!
Aggressive cleaning agents that can damage the paintwork must not be used on the EC fan. Water must not
enter the inside of the motor or the electronics (through direct contact with seals or motor openings, for ex-
ample), respect the protection rating (IP). The condensation drain holes (if present), positioned to suit the in-
stallation situation, must be checked for clearance. Run the EC fan for at least 1 hour at 80 to 100% of max-
imum speed before cleaning to prevent moisture accumulating in the motor! Run the EC fan for a minimum
of 2 hours at 80 to 100% of maximum speed after the cleaning process!
