IMPORTANT
Be sure to have read and understood these instructions before beginning the installation process.
Smoke Detectors
It is important that any open side of the plastic diffuser is not positioned within 1m of a smoke detector. If the diffuser cannot be repositioned, up to two sides of the diffuser may be closed off using the plastic blanking plate supplied (Loft only) so that the open sides face a minimum
1.5m unobstructed path away from the detector. In 3 floor properties a metal fire diffuser should be fitted at minimum of 1m from the detector (see page 9).
SAFETY AND RECOMMENDATIONS
• All wiring must comply with Building
Regulations and the current I.E.E. Wiring Regulations (BS7671) or the equivalent standards for your country. The final installation should be examined and tested by a qualified electrician.
• Precautions must be taken to avoid
the back-flow of gases into the dwelling from the open flue of gas or other fuel-burning appliances.
• Make sure the mains supply
complies with the rating label for voltage, frequency and phase.
• This appliance can be used by
children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

Installation Instructions
FIRST STAGE
Position a dustsheet beneath the site you have chosen for cutting the hole for the diffuser. Protect your lungs with a mask. Enter the loft space with the ECO2 Loft and check there are no obstructions to your chosen position for the diffuser. Using the template supplied mark the hole for the diffuser and cut the 220mm hole in the plasterboard (see page 9 for additional ECO2 Twin installation instructions). N.B The unit is designed to be taken apart and re-assembled to overcome restricted access through small loft hatches.
SECOND STAGE
Position the ECO2 Loft on 50mm x 25mm wooden battens (not supplied) laid across the joists or raised platform if the insulate is thicker than the joists so that the ducting between the unit and the diffuser is not impeded. Lightly screw the drilled battens to the joist through the rubber mounts and metal penny washer provided. Fit the ducting to the unit spigot using half of the tape provided.
THIRD STAGE
Push ducting through the hole in the ceiling. Return to the hallway and connect the ducting onto the neck of the diffuser using rest of the tape provided. Ensure that the diffuser is aligned correctly with the walls of the hallway. Adjust if necessary. Fix the diffuser in position using plasterboard plugs and the screws provided.
FOURTH STAGE
The ECO2 Loft must only be installed by a competent person and should be connected to an electrical supply in accordance with the current electrical regulations. A disconnection device should be used in the fixed wiring.
FIFTH STAGE
Check the unit is working correctly. Set the unit’s controls according to the house size and check that the filters are securely in place.
SIXTH STAGE
Method of operation: Adjust the settings on the top of the unit by pressing the house setting button. By pressing the button, the correct ventilation rate for the size of the house can be selected i.e. if the unit is on SMALL / TRICKLE and the button is pressed, the unit will then switch to MEDIUM.
Similarly, if the unit is on BOOST and the button is pressed, the unit will then switch to SMALL / TRICKLE.
As a rule of thumb, the setting on the ECO2 Loft should match the number of bedrooms i.e. 1 - 4

ECO2 Twin Installation Instructions
Twin Spigot
This addition to the fixing instructions explains the methodology of installing the twin spigot system.
This variation to the ECO
2
Loft is necessary where:
The hallway is very small, particularly when there is limited heating in the house
The loft hatch fills the hallway ceiling
Air is required to be diffused into a remote zone, such as a bedroom
Cut two 105mm holes in the ceiling in the positions chosen where air is required to be delivered. Use the distance from the ECO
2
Loft Unit to each hole to balance/favour airflow:
i. Equal air supply required - diffusers equidistant from unit ii. More air supply required in hallway - short run to diffuser in the hall
(This is the recommended method of installation)
Connect the flexi ducting to the twin spigot and hold in position with a cable tie on each outlet.

Example of installation: More air is required in hall - shorter run

Fire Installation Kit
For installations in 3 storey dwellings, it is necessary to fit an ECO
2
Loft with a fire kit, EnviroVent part number: KIT-PIV-SMOKE. It is important to follow the installation instructions that come with the kit.
Installation checks and maintenance
The fire system should be checked at installation to ensure proper function. The diffuser should be periodically checked to ensure they have not been activated and that they are still delivering air into the property. In the case of a fire, the system should be thoroughly checked.
Smoke alarm
For installations in 3 storey dwellings the ECO
2
Loft should be wired in such a way that it shuts down completely when the smoke alarm system is triggered. This can be done by linking the ECO2 Loft to relay type smoke alarm (N/C), see schematic. When the relay is triggered by the alarm, power to the unit will be interrupted and the unit will stop. When the alarm resets, power will be resumed to the unit and the ECO2 Loft will resume working at its previous settings.
