physical sensory or mental capabilities, or lack of experience and knowledge, unless

1.0 Introduction
The Brookvent Airstream ACE is a compact and highly efficient Mechanical Extract
Ventilation (MEV/CMEV) system, specifically designed for smaller dwellings and
apartments.
The system should be run continuously 24 hours a day and should only be disconnected
by a competent person during service or maintenance.
The system works by drawing stale air from ‘wet rooms’ such as Bathrooms, WC’s and
Kitchens and expelling waste air from the home. Simultaneously, fresh air is drawn into
the home, through passive vents in the walls or window in each habitable room.

4.0 Installation
It is important that the full installation of this system is carried out by competent persons,
including all electrical works and connections being completed by a qualified electrician.
The MEV unit is designed to be installed indoors, within an attic, storage cupboard, or
void space, away from exposure to frost, water, or intense heat. The system should be
installed in a ventilated space.
A clear access space is required around the unit; this will ensure ease of installation
relating to ductwork and wiring. It is important that the system can also be accessed for
replacement.
4.1 Mounting
Determine the best inlet and exhaust duct configuration to minimise bends close to the
unit.
Ensure there is adequate space to allow for maintenance of the unit and for end-of-life
replacement.
Fix the unit to the ceiling with fixing 4no. M6 anchors and M6 bolts (not supplied).
Place spigot caps on any of the outlets that are not being used.
Fit the ducting to the spigots and seal using duct sealant and/or aluminium foil tape.
Secure the duct in place with self-tapping screws (pilot hole may need to be drilled) or
metal banding and jubilee clips.
4.12 CEILING MOUNT
Please ensure that this method of fixing is suitable for the mounting surface and that it
can safely bear the load.
