INSTALLATION INSTRUCTIONS
SECOND STAGE
Position the ECO2Air Twin or ECO2 Loftight Twin unit 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 trunking between the unit and the diuser
is not impeded. Lightly screw the drilled battens to the joist through the rubber mounts and metal penny washer
provided. Fit the trunking 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
diuser using rest of the tape provided. Ensure that the diuser is aligned correctly with the walls of the hallway. Adjust
if necessary. Fix the diusers in position using plasterboard plugs and the screws provided.
FOURTH STAGE
Fit the lter as per the diagram below (ECO2Air Twin only)
Fig.1 Fixing Instructions
FIRST STAGE
Position a dustsheet beneath the site you have
chosen for cutting the hole for the diuser. Protect
your lungs with a mask. Enter the loft space with the
ECO2Air Twin or ECO2Loftight Twin unit and check
there are no obstructions to your chosen position for
the diuser. Using the template supplied mark the
hole for the diuser and cut the Ø107mm holes in the
plasterboard.
Use the distance from the unit to each hole to balance/
favour airow:
i. Equal air supply required - diusers equidistant from
unit
ii. More air supply required in hallway - short run to
diuser in the hall

INSTALLATION INSTRUCTIONS
FIFTH STAGE - Fitting the inline lter
Filter location - The lter should be located in the supply airow between the external input point and the unit. It is
recommended that it is tted directly to the ECO2 Loft Unit spigot in a section of Ø150mm x 350mm (min) ridged
duct. See Fig.4.
Filter Orientation - The cone lter should always point towards ECO2Air Twin and ECO2Loftight Twin.
Fixing and sealing - The lter should be fully sealed into the ducting, however it should not be permanently bonded
into position, this is to allow for removal of the lter during maintenance. Use a exible section as shown in Fig 1 &
Fig 4 to aid removal, 300mm is recommended. Always apply the label provided to the lter location, this is to assist
future lter maintenance (Fig 3).
Installation congurations - For sample congurations see (Fig 2).

Choose a location for the fresh air intake and drill a
ø158mm (or ø132mm) hole for wall kit. Depending
on the layout of your attic, you have three options for
locating the input of fresh air (wall input; roof input
and under tiles input). If ø125mm wall / roof kit is
installed, use an ø150mm adaptor to connect to the
unit with ø150mm insulated ducting. Make sure that all
connections are sealed well.
It is recommend that ø150 intake vent is used for best
performance
