4. Setup and Installation
The DX100TS is designed for through-the-wall installation. A 100mm diameter hole is required.

- Mount the External Grille: Secure the external grille to the exterior wall, ensuring it covers the outer end of the telescopic duct. Use the provided fixings.
- Electrical Connection: Connect the fan unit to the electrical supply. This model is a timer version, typically wired to a lighting circuit. Refer to the wiring diagram provided with the fan for correct connections. Ensure all connections are secure and insulated.
- Mount the Fan Unit: Secure the main fan unit to the interior wall, connecting it to the telescopic duct. The fan features a "twist and click" fascia for easy attachment and removal.

5. Operating Instructions
The DX100TS Timer Square fan operates with two selectable speeds and an adjustable timer function.
- Speed Selection: The fan offers two extraction speeds: 15 litres per second (54 m³/hr) or 21 litres per second (76 m³/hr). The desired speed setting is typically configured during installation.
- Timer Function: This model includes an adjustable timer, which can be set from 30 seconds to 30 minutes. When connected to a remote switch (e.g., a lighting circuit), the fan will activate when the switch is turned on. After the switch is turned off, the fan will continue to run for the pre-set duration before switching off automatically.
