envirovent Infinity NB Bathroom and Kitchen Extractor Fan Installation Guide

Safety

Read and understand these instructions before beginning installation. The unit should be installed by a competent person.

Check there is space to fit the unit in your chosen location. As standard it can be installed using 100mm or 125mm inside diameter duct. With the optional adaptor, a 150mm duct can also be used.

The unit can be wall mounted as standard, or ceiling, recess, inline and window mounted using optional kits (see page 15 for further information). The unit cannot be wall mounted upside down (with the electronic boards at the bottom) as this will void the warranty.

Ensure the operation of the unit does not affect the operation of open-flue appliances. If you are unsure, please consult local regulations or a qualified gas engineer. Consider the external cowl location in relation to open-flues from appliances e.g. boilers. You must ensure the cowl is positioned a minimum distance of 300mm away in all directions.

In kitchens, if the unit is fitted above a cooker, it must be installed a minimum distance of 1 metre above any hob, and not have a pullcord fitted.

This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge, unless they have been given supervision and usage instruction by a person responsible for their safety.

Children should be supervised to ensure they do not play with the unit. Cleaning and user maintenance must not be performed by children.

Electrical Connection
The fan must be able to be disconnected from the Mains supply after installation. When wiring the unit to the Mains power supply, a suitable local isolator must be incorporated in the fixed wiring in accordance with the IET Wiring Regulations. Connection to the fixed wiring must be made outside the unit in a suitable location.

The power cable running into the cable gland must remain the supplied flexible cable (not a solid core lighting and mains cable). If any other type of cable is forced into the cable gland, the unit will be damaged, voiding the warranty.

If the mains cable is damaged, it must be replaced by EnviroVent, an authorized service agent, or a similarly qualified person in order to avoid a hazard.

Do not remove or tamper with the electronic circuit boards inside the product. The unit requires a continuous electrical power supply and should not be wired through a light switch.

Wiring Regulations
All wiring must comply with Building Regulations and the current IET Wiring Regulations (BS7671 in the UK) or equivalent standards for other countries. The final installation should be examined and tested by a qualified electrician.

This product is not suitable for use with a Type AC RCD

About the Product

Function

The EnviroVent Filterless Infinity NB has been developed to improve indoor air quality, reduce humidity levels in kitchens and bathrooms and resolve condensation and mould problems. It is designed to operate continuously for up to 7 years without a major service.

Humidity Tracking

As standard, the unit is fitted with Intellitrac® Technology to sense the relative humidity in the room. Once above the setpoint, the fan speed will increase as humidity levels rise and decrease as humidity levels fall. This intelligent function reduces energy costs, motor wear, and ensures a long life for the product.

Cartridge Replacement

If necessary, the central cartridge can be exchanged for a replacement. The removed cartridge can be returned to EnviroVent for recycling. This allows the front cover, rear carcass and duct to remain intact throughout the life of the property, eliminating the wasteful disposal of non-biodegradable material to landfill sites.

Installation

ISOLATE THE MAINS SUPPLY BEFORE BEGINNING THE INSTALLATION

1. Loosen the two screws on the bottom of the unit, leave the screws in place and remove the front cover.

2. Pull the central cartridge out from inside the rear carcass.

3. Disconnect the green connector end of the power cable from the unit then set the central cartridge to one side.

4. Connect the power cable and local isolator to the Mains as in the wiring diagrams shown on page 5. Then tighten the cable gland on the rear carcass

5. Insert the rear carcass into the wall duct.

6. Fix to the wall using four of the labelled fixing holes and the four screws and wall plugs provided.

7. Insert provided caps into the fixing holes at the top of the rear carcass (1, 2, 3). Not using these will void the IP rating and warranty.
   

8. Reconnect the green power connector to the unit.

9. Insert the central cartridge into the rear carcass. Do not trap any of the cables. Fix in place using the four supplied screws.

10. To change unit settings, adjust switches 1 and 2 on the central cartridge.
    a) Default 230V duty is kitchen + humidity tracking.
    
    b) Default SELV duty is bathroom + humidity tracking.
    

11. Now apply the adhesive foam pad over the switches. Not using this will void the warranty and IP rating.
    

12. Ensure the impeller is fitted correctly, the two clips should both be engaged.
    

13. Replace the front cover. On pullcord variants, ensure the pullcord sits into the front cover slot. The unit will not operate without the front cover in place.
    

14. The mains supply can now be reactivated.
    

Troubleshooting

• Is there power being supplied to the unit?
• Are all internal electrical connectors attached or have any been disconnected?
• Has the electronic circuit board been removed for any reason?
• Is the central cartridge correctly seated in the rear carcass with no stray wires obstructing it?
• Does the impeller spin freely? Ensure the two clips have been fully engaged.
• Is the front cover in place? The unit will not operate until the front cover is fitted.
• Does the pullcord activate? Ensure the pullcord is not trapped inside the unit.

Wireless Remote Control

When the button on the remote control is pressed, the unit will extract at the maximum extraction rate for up to 15 minutes then return to the low extraction rate. The high extraction rate can be stopped early if required, by pressing the button on the remote control within the 15 minutes. (Remote control units do not include a pullcord).

Pullcord

If your Filterless Infinity Fan includes a pullcord, it can be used to engage the maximum extraction rate for odour control. Pull down on the cord to increase the unit to the maximum extraction rate. Pull down again to decrease the unit back to the low extraction rate.

To pair additional remote-control
switches:

1. Turn the unit off at the isolation point.
2. Restore power; for 20 seconds from restart the unit will be in pairing mode.
3. Press the remote button once within the 20 seconds and the control will pair to the unit.
4. Successful pairing is indicated by a green light on the control.

Batteries

When the battery (CR2032 type) requires changing, unscrew the switch front cover. The battery is located on the back of the cover. The switch will remain paired with the unit after battery replacement. Ensure the new battery is inserted with correct polarity, and the removed battery is safely disposed of.
