Damper Inspection
The spring mechanism keeps the dampers on stand-by mode throughout their entire operational life.
Without the producer’s permission, there must be no changes or modications performed on the dampers’ structure.
The operator performs regular inspections of the dampers as per established regulations and standards at least once
every 12 months. The inspection needs to be performed by an employee who has been specically trained for this
purpose by the manufacturer. The current re damper condition determined during the inspection needs to be entered
into the
“Operating Journal” along with the date of the inspection, the legible name, surname and signature
of the employee who performed the inspection. The Operating Journal includes a copy of the employee’s
authorization. If any discrepancies are discovered, these need to be entered in the Operating Journal along
with a proposal for their removal. The Operating Journal can be found from page
28 of this manual. Before the
rst installation, it needs to be inspected under the identical conditions as apply to the above mentioned 12-month
inspections.
It is needed to inspect the damper’s internal casing, the thermal fuse link, the sealing, the foaming substance,
the damper blade’s condition and its closure while it leans to a backstop in a closed position.
There must be no other objects or dirt from the ventilation duct inside the damper.
NEVER INSPECT THE DAMPERS WHEN THERE IS AIR FLOWING IN THE DUCT SYSTEM!
Recommended Inspection Steps According to the EN 15 650 Regulation
1. Date of inspection
2. Check of the end switch’s connection for damage if applicable
3. Check for damper cleanliness and cleaning if needed
4. Check of the blades and sealing, correction and record if nee¬ded
5. Check of re damper’s safe closure – for details please see the previous section
6. Check if the damper moves while being in its open and closed position, correction and record if needed
7. Check of the end switch indicating the open and closed positi¬on, correction and record if needed
8. Check if the damper is moved in its standard position. The PKI-C damper’s position is correct when,
after the closure, the bla¬des are in between the planes forming the outside surface of the wall
– the ideal position is when the blade is in the middle between these planes.
Fire Damper Functionality Check
1. While performing the check, focus on the thermal fuse link’s integrity and a correct position of the damper blades
after their detention in the OPEN position – they should be roughly parallel to the longitudinal axis of the duct.
2. Perform the damper activity check by taking off the thermal fuse link and releasing the blades to spontaneously
close them – the damper blades are closed by a spring return release.
3. If using the DV1 or DV1-2 version, the blade’s position is indicated by a connection of the respective circuit shown
on
Fig. 24 or Fig. 25.
4. Open the blades again and detent them in the OPEN position following instructions shown in section
“Operation Manual”.
5. When remounting the damper into the duct it is also essential to check the exibility of the sealing
on the perimeter and in case it shows permanent deformation, it is needed to replace the seal with a new one
in order to guarantee a correct xation of the damper in the duct.
