Project sourcing brief

## Plan the specification before the order.

### Buyer scenario

HVAC integrators and central-scent project providers coordinating with building engineers.

### Typical space requirements

Collect duct layouts, airflow, zones, accessible connection points and maintenance restrictions before equipment selection.

### Selection considerations

SDL820 and SDL821 are models to discuss, not a claim of verified duct compatibility. Obtain connection details and model-specific installation approval; do not assume direct HVAC connection.

### OEM / project support

Agree compatibility review, installer responsibilities, operating limits and service access before sample approval or procurement.

These are selection considerations, not verified installation case studies. Coverage is expressed in m³; model-specific installation documents remain subject to confirmation.
