Louver dampers
Commissioning
If multiple dampers are coupled with one another, the connecting
rods should be checked for proper seating and freedom of
movement.
If drive is accomplished by means of a servo-motor, the rods are to
be adjusted so that a rotation angle of 90° is warranted and the
louvers will reach their end position when closing.
The louver damper positioner can be mounted on the interior, as
well as on the exterior of the housing. It should be mounted on the
interior of those units designed for outside use, or protected against
moisture.
During commissioning, the louvers must be driven to all required
operating positions. The respective louver position must correspond
to the control drive (end-switch setting).
Maintenance
Check the louver dampers for contaminants and damage.
-
Where geared drives are used, special attention should be
given to clean toothing.
Check mechanical function
-
Damper positioning motors are to be checked and possibly re-
-
adjusted for proper mounting and the correct end-positioning
Freedom of movement and leak-tightness of the dampers will
-
be determined after decoupling the positioning drive.

Rotation heat exchanger
General
The drive motor is easily accessible via the removable covering
panels and quick release fasteners.
In order to avoid damage when cleaning, an air or water jet-spray
should be directed at the storage mass only at right angles.
If the power supply has not been interrupted on all phases, a
danger of crushing or abrasion exists due to the possibility of a
sudden rotor start-up via an automatic cleaning process or and
automatic re-start following a power failure.
Commissioning
Prior to commissioning, it must be ensured that no objects are
allowed to block the free movement of the rotor. Remove foreign
objects and contaminants.
Check sealing strips for contact pressure. These must be pushed in
as close as possible to the storage mass, whereby a direct rubbing
contact under operating pressure conditions must be avoided.
As a matter of course, rotor mounting will be aligned at the factory.
Re-alignment may be necessary, however, depending upon the
installation conditions. In this regard, please observe the
manufacturer's operating instructions.
Because the v-belt is subject to a natural stretching, v-belt tension
should be regularly checked, especially within the first 400
operating hours.
