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 ECO2Loft 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 ECO2Twin 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 ECO2Loft 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 ECO2Loft 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 ECO2Loft should match the number of bedrooms i.e. 1 - 4
