Interior comfort, air quality and energy eciency are vitally important considera-
tions in buildings today. The Titon CME1 has been developed to meet these de-
mands by extracting stale polluted air from the building whilst fresh air is provided
by passive means.
For the home owner or occupant, this Product Manual explains:
Why ventilation is vital for the good health of your home and its occupants.
How your Titon CME1 system works.
How to operate and maintain your Titon CME1.
For the professional installer, this Product Manual explains:
How to install the Titon CME1.
How to commission the unit.
How to maintain the unit.
It is important to read this Product Manual to ensure your ventilation system is
installed, commissioned and used properly and continues to operate eectively.
Failure to follow the guidance provided in this manual can have an adverse eect
on health.

Ventilation is Vital
Construction methods used in older homes resulted in uncontrolled ventila-
tion via air leaking through the building structure, such as small gaps around
windows and doors or between walls and oors. These leaks allowed a large
amount of air to move through a home largely unnoticed by the occupants. Other fac-
tors, such as open replaces, people being at home more often and opening windows
to “air” rooms during daytime, all helped maintain reasonable levels of air quality in
homes.
However, because this form of ventilation was uncontrolled, a large proportion of
heat escaped to the outside and more energy was needed to make up for this loss.
Modern homes have greatly reduced air leaks and indoor air quality can deterio-
rate rapidly without the use of products made to control ventilation Chemicals, gases
and moisture produced by everyday
products and activities may lead to the
build up of excessive levels of pollutants
which are harmful to the health of the oc-
cupants and may damage the building.
Poor ventilation can be a major
contributory factor of heart disease, lung
disease, mental illness and many more
threats to our health.
The World Health Organisation and
responsible Governments around the
world recognise the vital importance
of good indoor air quality. That is why
building regulations govern the way homes are designed and built. Once homes are
occupied it is the responsibility of the occupants to make sure they use and maintain
the ventilation products following the guidance provided.
Ventilation an essential ingredient
CME1_Q_Plus_Product_Manual.indd 5CME1_Q_Plus_Product_Manual.indd 5 24/09/2009 15:15:2024/09/2009 15:15:20

The Titon CME1 works by continually extracting stale polluted air from rooms
where most moisture is generated. Fresh air is provided passively from outside
to habital rooms, creating a ow of fresh, clean air throughout the home. The air
travels from terminals built into the ceiling which are connected by hidden ducts to
the unit. The unit is usually installed in a roof space or cupboard.
Each unit is commissioned individually so the amount of air moved is set to suit
the specic size and style of the home.
Most systems will also have a facility to boost the extraction rate at times when
more moisture is being generated, such as when bathing or cooking. This may be
done automatically by electronic sensors or by a conveniently located boost switch for
manual operation.
DO NOT switch o the unit; it is designed to run continuously. If the unit is switched
o indoor pollutant and moisture levels may increase and become a danger to
your health and damage your house.
It is important to follow the advice in this user manual and correctly maintain the
system to ensure a healthy indoor environment.

How to Use the System
The unit runs automatically and should not be switched o, except for mainte-
nance. If a boost switch has been installed, it can be used to increase the extract
ventilation rate at times when moisture or pollutant levels are considered exces-
sive. You may have electronic sensors which detect high levels of moisture and pollut-
ants which boost the system automatically.
All ventilation units require periodic maintenance and this must only be carried
out by a suitably qualied and competent person. See the servicing and maintenance
section for further details.

Ducting Best Practice
The use of exible ducting must be kept to a minimum and it should always be
pulled taut.
If applicable, Fire Dampers must be tted to duct work at appropriate locations in
accordance with Building Regulations.
Ducting must be installed in such a way that resistance to airow is minimised.
Ducting terminal for Exhaust must be to the external air outside the building
envelope.
We recommend a minimum distance of 200mm between the appliance and any
sharp bends in duct work.
Ducting in unheated spaces must
always be insulated to prevent
condensation forming within the
ducting.
Additional guidance can be found in
the Residential Ventilation Associa-
tion Instillation Good Practice Guide
and Approved Document Part F.

Installation
Wiring
WARNING: The unit MUST be earthed. All wiring must conform to current I.E.E.
Wiring Regulations and all applicable standards and Building Regulations.
The unit is suitable for 230V~50Hz Single phase supply fused at 3A.
A double pole isolation switch with contact separation of at least 3mm must be
used to connect the appliance to the xed wiring.
Boost controls must not be located within 1 metre of a cooker or where they may
be aected by excessive heat or moisture
Boost controls should be clearly identied and conveniently located.
The boost switch wiring must not be connected to the mains supply.
The boost switch is connected to the control board (which is located under the
COVER on top of the SCROLL).
The boost switch wiring cable access is via cut outs in the COVER.
The boost switch wiring connection to be made by the 5v+ and SW terminals on
the control board.
The boost overrun can be triggered by any device which provides a one-way
switch, such as a PIR, thermostat, humidistat or a standard one-way switch.
The boost facility features a overrun timer, so we recommend a sprung-return
(momentary) switch is used to prevent the boost being accidentally left on for
longer than intended.
