The Manrose XFS/XPS range of extractor fans, as well as other models like the Classic Series, DECO, LP, and quiet QF series, are designed for ventilation purposes. Installation requires adherence to specific guidelines to ensure safe and effective operation. These fans are double-insulated and comply with EN60335-2-80:1997, carrying a CE mark. Installation should be performed by a qualified electrician, and specific considerations apply based on the fan model – standard, pullcord, timer, or humidity-sensing. Proper electrical connections and adherence to safety precautions are paramount.
Installation Procedures
Installation of Manrose extractor fans involves several key steps. Initially, the fan should be positioned as high as possible on a wall or ceiling (excluding pullcord models) for optimal performance. Installation within shower cubicles or areas prone to direct water spray is not recommended. Prior to commencing any electrical work, the mains power supply must be switched off.
The installation process includes cutting a hole in the wall or ceiling to accommodate the fan and ducting. The maximum hole size corresponds to the duct diameter, with dimensions varying by model (e.g., 100mm/4” fans require a 112mm hole, 120mm/5” fans require a 135mm hole, and 150mm/6” fans require a 173mm hole). When installing in a ceiling, ensure the hole is positioned between joists. Ducting should be fitted flush to the plaster.
To access the fan’s mounting points, the cover must be removed by disengaging the two small screw caps and retaining Philips screws on the front cover. The fan body is then held against the wall or ceiling, and the screw holes and cable entry point are marked. It is crucial to ensure the fan is square during this marking process. After drilling holes and inserting appropriate wall plugs, the fan is secured with No 8x 1 ¼ screws.
A permanent live and neutral supply is required for all models. For models installed through an external wall, an external wall grille must always be fitted. An extra 230mm (9”) of cable should be left protruding to facilitate connections. The duct and cable should then be properly secured. Fans should be installed a minimum of 1.8 meters from the floor.
Electrical Connections: Model-Specific Guidance
The electrical connection procedure varies depending on the fan model.
Standard Model: The fan can be operated from a separate pullcord switch on the ceiling or connected to the light switch, requiring only a live and neutral supply.
Pullcord Model: This model also requires only a live and neutral supply, with an integral on/off switch.
Timer Model: Similar to the standard model, the timer model can be operated from a pullcord switch or the light switch. It features an adjustable timer ranging from 30 seconds to 20 minutes.
Humidity Model: This model requires a permanent live and neutral supply connected via a remote switch or fused spur unit. It activates when humidity rises above a pre-set level and continues running until the humidity falls 5% below that level. In new constructions, the fan may run for extended periods due to consistently high humidity. The humidity setting is adjustable via a knob.
Humidity Model with Pullcord: This model requires a permanent live and neutral supply and includes an integral pullcord on/off override switch, alongside adjustable humidity settings.
Humidity Model with Timer: This model combines the functionality of the humidity sensor with a timer circuit, allowing the fan to run for a pre-set duration after being switched off remotely, but will still activate based on humidity levels. The timer is adjustable from 30 seconds to 20 minutes.
Automatic Backdraft Shutters
Many Manrose fans incorporate an electronic thermoactuator-operated backdraft shutter system. These shutters open and close in 30-60 seconds when the fan is switched on and off, respectively.
Safety Precautions and Compliance
Several safety precautions must be observed during installation and operation. The system should be installed by a qualified electrician. The appliance is not intended for use by young children or infirm persons without supervision, and children should be supervised to prevent them from playing with the appliance. Precautions must be taken to prevent back-flow of gases from open-flue gas appliances. All fans are double-insulated and do not require an earth connection. The manufacturer reserves the right to change specifications without prior warning.
Rating and Specifications
The documentation directs users to refer to the fan’s rating and wiring label for specific electrical power and IP ratings. All fans are manufactured to comply with EN60335-2-80:1997 and are CE marked.
