The dampers are transported as bulk cargo in covered means of transport. The dampers can be
transported on pallets or in crating upon accord with the customer. For handling during transport
and storage, the dampers must be protected against mechanical damage. The potential
packages will be considered non-returnable and their price will not be included in the damper price.
Unless another method of reception is specified in the purchase order, the handover of the
dampers to the forwarder shall be understood as reception.
The dampers must be stored in covered buildings, in an environment without aggressive vapours,
gases and dust. A temperature in a range of -5°C and +40°C and a relative humidity of max. 80%
must be maintained in the buildings. For handling during storage, the dampers must be protected
against mechanical damage.
The manufacturer provides a warranty of 24 months from the date of dispatch for the dampers.
If the dampers are damaged by transport, a record must be written down with the forwarder at
reception for later complaint.
The assembly of the dampers must be carried out while observing all applicable safety standards
and regulations.
Before putting the dampers into operation and during subsequent operability inspections, the
following points must be visually checked: correct incorporation of the damper, interconnection of
all metal parts and, if actuator or limit switches are attached, correct connection.
The flange and screw connections must be conductively connected during assembly, for protec-
tion against hazardous contact according to EN 332000-4-41,-4-47 and -5-54. 2 fan-shaped
washers in galvanized design are to be used for conductive connection; they are to be situated
under the head of one bolt and under the screwed nut.
The assembly consists in installation of the damper into the air-conditioning piping.
