4. Tāutanga

Follow these general steps for installing the ALDES OCTA Passive Sound Trap. Specific installation methods may vary based on your ventilation system configuration.

1. Whakanoho Mahere: Identify the optimal location in your ductwork where noise attenuation is most needed. The sound trap should be installed in a straight section of ducting, away from bends or obstructions, for maximum effectiveness.
2. Whakapaia te Mahi Torangapu: Ensure the duct ends are clean, smooth, and free from burrs. The duct diameter should match the D125 (125mm) diameter of the sound trap.
3. Insert Seal: If the seal is separate, ensure it is correctly positioned on the sound trap's connection points or within the ductwork to create an airtight seal.
4. Connect Sound Trap: Carefully insert the sound trap into the prepared ductwork. Ensure a snug fit.
5. Hononga Haumaru: Whakamahia cl tikaamps, screws, or duct tape (as per local regulations and system requirements) to secure the sound trap to the ductwork. Ensure all connections are airtight to prevent air leakage and maintain system efficiency.
6. Tautoko: For longer or heavier installations, provide additional support for the sound trap and ductwork to prevent sagging or stress on connections.
7. Tirotiro: After installation, visually inspect all connections for proper sealing and secure mounting.

5. Mahi

The ALDES OCTA Passive Sound Trap D125 + Seal is a passive device and does not require electrical power or active controls for its operation. Once correctly installed within the ventilation system, it functions continuously to reduce noise levels.

• Haruru Attenuation: The sound trap works by absorbing and dissipating sound energy as air passes through its specially designed internal structure, which includes a perforated inner casing and sound-absorbing material (not explicitly mentioned in description but implied by "passive sound trap").
• Rererangi: Ensure that the sound trap is not obstructed internally, as this could impede airflow and reduce the efficiency of your ventilation system.
• Continuous Function: The device operates whenever the ventilation system is active, providing ongoing noise reduction.

6. Tiaki

The ALDES OCTA Passive Sound Trap D125 + Seal requires minimal maintenance. Regular inspections are recommended to ensure optimal performance.

• Tirotiro Ataata (Ia Tau): Periodically inspect the exterior of the sound trap and its connections for any signs of damage, corrosion, or loose fittings.
• Internal Inspection (Every 2-3 Years or as needed): If accessible, inspect the interior for any accumulation of dust, debris, or foreign objects that might obstruct airflow or reduce acoustic performance. Clean if necessary using a soft brush or vacuum cleaner.
• Hiri Tika: Check the integrity of the seal at the connections. Replace if cracks or deterioration are observed to maintain airtightness.
• Te horoi: Do not use harsh chemicals or abrasive materials for cleaning. A damp he rawaka te kakahu mo te horoi o waho.
