Accessories
Actuator:
Sauter ASM115SK005, ASM124SK002, 24 V AC, standard
actuators depending on size.
Other actuators must be ordered, see actuator table page 3.
Wiring diagrams are displayed on pages 2 to 3.
Knob:
CRTT-1 for manual control.
Quick connection:
FSR. Clamp with quick-acting lock.
Installation
Damper is Inserted into the connecting duct and fixed in
position by pop rivets or by means of an FSR clamp. See
Figures 1 and 2.
Commissioning
Connect hoses from a manometer to the measurement
nipples. Turn and lock the damper blade at the desired
setting angle For particulars of motorised control, we
refer to the actuator supplier’s instructions. K-factors are
shown on the product’s identification label. The K-factor
can also be found in the table, page 4.
Maintenance
Clean the damper whenever needed by means of a
vacuum-cleaner or by wiping surfaces with a cloth.

Figure 5. Installation of actuator CRM 5, size 500 and 630.
First, close the damper entirely, then install the actuator exactly
straight and lock it against the damper shaft. Turn the actuator 5°
past closed setting and lock the position of the actuator.
