Setup Guide

This section provides general guidance for the installation of your Vent-Axia VASF100T fan. Installation should be performed by a qualified electrician in accordance with local wiring regulations.

1. Safety First: Before commencing any electrical work, ensure the main power supply to the circuit is switched off at the consumer unit/fuse box. Verify with a suitable voltage tester.
2. Mounting Location: Choose a suitable wall or ceiling location in the bathroom or WC, ensuring adequate space for the fan unit and ducting. The fan is designed for wall mounting.
3. Prepare Opening: Create an appropriate opening for the fan body and ducting, typically 100mm in diameter, ensuring it is clean and free of debris.
4. Wiring: Connect the fan to the electrical supply. This model requires a permanent live, switched live (from light switch), and neutral connection. Refer to the wiring diagram provided with the product packaging for specific terminal connections.
5. Speed Selection: During installation, select one of the two available speeds. This is typically done via a jumper or switch on the fan's PCB. Consult the product's internal instructions for precise details on speed setting.
6. Timer Adjustment: The overrun timer can be adjusted between 5 and 30 minutes. This adjustment is usually made via a small potentiometer on the fan's PCB using a small screwdriver. Set the desired overrun time before final assembly.
7. Secure Fan: Secure the fan unit firmly into the prepared opening using appropriate fixings. Ensure the back draught shutter operates freely.
8. Final Assembly: Attach the front cover of the fan. Restore power to the circuit and test the fan's operation.

Operating Instructions

The Vent-Axia VASF100T Silent Fan is designed for simple, automatic operation once installed and configured.

• Standard Operation: The fan is typically wired to operate in conjunction with your bathroom light switch. When the light is switched on, the fan will activate.
• Timer Function: After the light is switched off, the fan will continue to run for the pre-set overrun period (adjustable from 5 to 30 minutes). This ensures effective removal of moisture and odors even after the room is vacated.
• Continuous Operation (if configured): While primarily designed for intermittent operation with a timer, some installations may configure the fan for continuous low-level ventilation. Refer to your installer for specific wiring details if this is the case.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Vent-Axia VASF100T fan.

1. Power Disconnection: Always disconnect the fan from the main power supply before attempting any cleaning or maintenance.
2. Exterior Cleaning: Periodically wipe the exterior of the fan with a soft, damp cloth. Do not use abrasive cleaners or solvents.
3. Internal Cleaning: Carefully remove the front cover of the fan. Gently wipe away any dust or debris from the fan blades and internal surfaces using a soft brush or cloth. Ensure no moisture enters the electrical components.
4. Check for Obstructions: Ensure the air inlet and outlet are free from any obstructions (e.g., lint, dust build-up) that could impede airflow.
5. Reassembly: Once clean, carefully reattach the front cover, ensuring it is securely fitted.
6. Frequency: Cleaning frequency depends on usage and environmental conditions, but a quarterly check is generally recommended.
