OPTIONAL ACCESSORIES ASSEMBLY
General Information
1. Optional discharge accessories such as tapered hoods, positive closure dampers, discharge sound
attenuators, desuperheaters, plume abatement coils and/or access plenums can be fitted.
2. Rigging method of optional accessories is indicated in the rigging tables.(see "General notes" on page 11
3. If the delivery consists of separate sections, do not assemble before lifting, as the lifting devices provided are
not designed to support the weight of the entire assembly.
4. Refer to the unit certified drawing for installation sequence of optional accessories.
5. Position the unit of the supporting steel and bolt in place.
6. Remove any protective wood from the top horizontal flanges of the lower section. Wipe down the flanges to
remove dust, dirt or moisture that may have accumulated during shipment and storage.
7. Apply the 25 mm wide tape sealer around the periphery of the top flange of the unit.
This tape sealer must be centred directly over the centreline of the tapper holes and on the centreline of the end
flanges where there are no tapper holes. The sealer is to be spliced only along the flanges with tapper holes. When
it is necessary to splice sealer, mitre and press the two ends together so as to form a smooth, continuous bead.
Tape sealer is trapezoidal in shape and must be installed wide side down (see figure "Installation of tape sealer").
Do not stretch sealer tape.
8. Sealer applied to the end flanges of the unit must be continuous.

3.
25 mm flat tape sealer laid over punch line wide side down.
When rigging the discharge accessory one might consider to hang the discharge accessory under a small angle (1-
2°) in the crane. This way one short end can be positioned first and then the rest of the discharge accessory can be
lowered slowly.
Once the discharge accessory is put on the tape sealer,
it can not be moved any more so gentle positioning is required.
