CHECKING FANS AND AIR VENTS

A fan defect immediately poses a danger of overheating that may
result in damage to the control unit, therefore the fans must be
checked once a month.

Control Unit Fans

respective fan must be replaced.
(2) Check the fan filters of the controller (2 on the left side and 2 on
the right side) for blockages and dirt. If necessary exchange
them. This may be easily done from the outside without opening
the controller.
