4. Installation
The DVF100 fan is designed for concealed operation, ideal for short duct runs in applications such as bathrooms or utility rooms.
4.1 Mounting the Fan Unit
- Select a suitable location for the fan unit, ensuring it is accessible for maintenance but concealed for discreet operation.
- Secure the fan unit to a solid surface (e.g., ceiling joist, wall stud) using appropriate fixings. Ensure the unit is level.
- Connect the flexible ducting to both ends of the fan unit and to the internal and external grilles. Use cable ties or clamps to ensure airtight connections.
4.2 Electrical Connection
WARNING: Electrical installation must be performed by a qualified electrician. Ensure power is OFF at the mains before proceeding.
- Locate the electrical terminal block on the fan unit.
- Connect the live (L), neutral (N), and switched live (SL) wires from your electrical supply to the corresponding terminals on the fan. The switched live connection is for the timer function, typically connected to the room's light switch.
- Ensure all connections are secure and correctly insulated.
- Close the terminal cover securely.
5. Operating Instructions
5.1 Basic Operation
The DVF100 fan operates when the switched live input is activated, typically by turning on the room's light switch. The fan will run for a set period after the light is switched off, thanks to its integrated timer.
5.2 Timer Adjustment
The fan features an adjustable run-on timer. To adjust the timer setting:
- WARNING: Disconnect power at the mains before opening the fan unit.
- Carefully open the fan unit cover to access the timer adjustment screw or dial.
- Using a small screwdriver (if applicable), gently turn the adjustment mechanism to increase or decrease the run-on time. Refer to the markings on the unit for guidance (e.g., '+' for longer, '-' for shorter).
- Close the fan unit cover securely.
- Restore power and test the new timer setting.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your fan unit.
6.1 Cleaning
- WARNING: Always disconnect the power supply before cleaning.
- Remove the internal and external grilles. These can typically be unclipped or unscrewed.
- Wipe the grilles with a soft, damp cloth. Mild detergent can be used if necessary. Ensure they are completely dry before reattaching.
- Carefully wipe the fan blades and the interior of the fan casing with a dry or slightly damp cloth to remove dust and debris. Avoid getting water into electrical components.
- Reattach the grilles securely.
6.2 Periodic Inspection
Periodically check the ducting for any signs of damage or blockages. Ensure all connections remain secure.
