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.

Introduction

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 every-
day products and activities may lead to
the build up of excessive levels of pol-
lutants which are harmful to the health
of the occupants 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 in-
door 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

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 habitable 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.

Installation
Safety and Guidance
The electrical installation of the appliance MUST be carried out by a suitably quali-
ed competent person and all wiring must be in accordance with current I.E.E.
Regulations and all appropriate standards and applicable regulatory guidance.
The appliance must be connected to a local isolation switch with a contact sepa-
ration of at least 3mm.
The appliance is suitable for 230V ~ 50/60Hz single phase with a fuse rating of 3A.
Ensure that external grills are located away from any ue outlet, in accordance
with relevant Building Regulations.
Always ensure ducting is free from blockages before switching the unit on.
We recommend a minimum distance of 200mm between the appliance and any
sharp bends in duct work.
Installation of the appliance MUST be carried out by a qualied and suitably
competent person and should be carried out in clean, dry conditions where dust
and humidity are at minimal levels.
The appliance is not suitable for installation to the exterior of the dwelling.
For ducting recommendations see Ducting Best Practice, page13.
Failure to comply with any of the above points will have an impact on the validity
of your guarantee.

Preparation
Important: read these instructions fully before the installation of this appliance
NEVER install the CME1 in an area which does not have sucient access the for
future maintenance (see Dimensions) , or‘box-in’the unit, as the area may subse-
quently surface nished making access to the unit dicult.
NEVER install the appliance in an environment which contains:
Excessive oil or a grease laden environment.
Hazardous gases, liquids or vapours that are ammable or corrosive.
Ambient temperatures above 40°C or below -5°C.
Humidity levels above 90% or a wet environment.

Fixing
The CME1 must be securely xed to a
smooth at surface, any orientation
is possible.
Mark the four xing hole centres
using the BASE as a template
Drill holes for xings, use 4mm
Pan Head screws. Always use a
xing type and length suited to
the substrate type. The unit weighs
approximately 5kg.
Mount the BASE, ensuring it is not
distorted by the xings or mounting
surface.
Clip the MOTOR and LID assembly to
the BASE, ensure that all 6 clips have
engaged.
Do not use power tools to tighten
screws. Tighten screws by hand.
Do not over tighten screws.

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.
We recommend a minimum distance of 200mm between the appliance and any
sharp bends in duct work.
Ducting terminal for Exhaust must be to the external air outside the building
envelope.
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 Installation Good Practice Guide
and Approved Document Part F.

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~50/60Hz Single phase supply fused at 3A.
For connection of the mains and boost trigger switch a terminal block is tted
inside the unit, under the cover. Note: strain relief for the cables is provided.
A double pole isolation switch with contact separation of at least 3mm must be
used to connect the appliance to the xed wiring.
A boost switch must be connected for the unit to run, see wiring diagram (a con-
nection is required between COM and L1 or L2 for the unit to operate).
Boost controls must not be located in a bath/shower room or 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 can be operated by any device which provides a two-way switch suit-
able for a 230V/3A mains power supply.
