PART II-14
MAINTENANCE AND REPAIRS
The following technical and hygienic maintenance work
must be carried out by trained cleaning personnel or
qualified technical personnel.
Technical maintenance
Regular technical maintenance work
Filter cell (ISO Coarse 60 %)
The filter cell must be replaced at regular intervals – at least every 12 months. The cell is replaced by hand from the side
of the unit. The filter cell is available as a spare part. If filter media from other manufacturers are used, reductions in caloric
output and increases in sound power may occur.

(available as a spare part).
Figure 2: Pivoting of the acoustic sail
ensures ease of access for maintaining
and inspecting the unit (VDI 6022).

Opening the acoustic sail
(Applies only to the INDUSAIL SONIC plus)
Overhead hazard!
A risk of personal injury and damage to equipment
directly below the acoustic sail may occur when
pivoting open the sail. Consequently, a safety area
extending one metre to the sides of the unit and 1.2 m
below the unit must be cleared before maintenance.
The acoustic sail must be supported manually as it is
pivoted open. Clean, white gloves must be worn when
carrying out all work, in order not to contaminate or
damage the sail.
In line with VDI 6022, the unit sections through which air flows are easy to clean. The fan and heat exchanger are maintained
in this case by pivoting open the acoustic sail. To do this, remove the side cover and undo the M8 nuts (optionally with an
eccentric lever with inside thread). The acoustic sail can then be carefully pivoted down.
