the joist through the rubber mounts and metal
penny washer provided. Fit the trunking to the
unit spigot using half of the tape provided.

Installation Instructions
FIFTH STAGE - Fitting the inline filter
Filter location - The filter should be located in the supply airflow between the external input point and
the unit. It is recommended that it is fitted directly to the ECO2Air Unit spigot in a section of Ø150mm x
350mm (min) ridged duct. See Fig.4.
Filter orientation - The cone filter should always point towards ECO2Air unit.
Fixing and sealing - The filter should be fully sealed into the ducting, however it should not be
permanently bonded into position, this is to allow for removal of the filter during maintenance. Use a
flexible section as shown in Fig 1 & Fig 4 to aid removal, 300mm is recommended. Always apply the
label provided to the filter location, this is to assist future filter maintenance (Fig 3).
Installation configurations - For sample configurations see (Fig 2).
