Titon gives a three-year warranty
on the Titon WCME100 ventilation
unit starting from the date
of installation. The installer/
technician must record the date of
installation into the panel on the
reverse of this User Manual. The
warranty covers the delivery of
a replacement service module by
Titon (basic printed circuit board
and the motor/fan assembly).
It does not cover:
• Reimbursement of costs incurred
by third parties.
• Faults or damage that are, in our
opinion, the result of improper
usage, handling, carelessness or
accidents.
• Faults or damage caused by
handling or repairs by third parties
without our permission.
• Faults or damage that are the
result of irregular and/or inexpert
maintenance.

SAFETY AND GUIDANCE NOTES
• All wiring must be in accordance
with the current I.E.E. Regulations
or the appropriate standards
of your country and MUST be
installed by a suitably qualified
technician/electrician.
• The unit should be provided with
a local double pole isolator switch.
• The fuse rating should be 3A.
• Ensure that the mains supply
(Voltage, Frequency and Phase)
complies with the rating label on
the unit.
• The unit should only be used in
conjunction with the appropriate
Titon products.
• When the unit is used to remove
air from a room containing a fuel
burning appliance, consult Part
J of the Building Regulations
(England & Wales).

Interior comfort and energy
efficiency are becoming increasingly
important considerations in building.
More and more equipment is being
developed to control the climate
within the home while meeting
these requirements. One such
device is the Titon WCME100.
A Titon WCME100 has been
installed in your home. In this User
Manual you will find information
about the necessity of good
ventilation and how your Titon
WCME100 works. Additionally,
we explain how to operate and
maintain the unit.
It is important that you read this
User Manual thoroughly before
using this ventilation system in
your home.
IMPORTANT: READ THESE
INSTRUCTIONS BEFORE
COMMENCING THE INSTALLATION.
DO NOT install this product in
areas where the following may be
present or occur:
• Excessive oil or a grease laden
atmosphere.
• Corrosive or flammable gases,
liquids or vapours.
• Ambient exhaust temperatures
higher than 40°C or less than -5°C.
• Relative humidity above 90%.
• Possible obstructions which
would hinder the access or removal
of the unit.
• Sudden ductwork bends or
transformations close to the unit.
DO NOT remove the front
access cover of the unit without
electrically isolating the unit
(remove fuse to ensure unit cannot
be accidentally switched back on
again).

Construction methods in the
past resulted in many places in
the home where air could “leak”
through, for example, through
gaps between the walls and floor
and between the walls and roof.
Moreover, windows and doors did
not seal completely when closed.
A fairly large volume of air could
move into and out of the home
through all these openings. If a
light wind was blowing, the entire
volume of air in the home was
ventilated two to four times per
hour. This meant that a lot of
energy was lost in heating that air,
but the ventilation was excellent.
It is a misconception to believe that
a modern building is ventilated
sufficiently when the ventilation
system in the home is turned off.
In an airtight building, ventilation
is absolutely essential to prevent
damp, the growth of mould and
To permit maintenance, the unit’s
front cover can be removed with a
screwdriver. Insert the screwdriver
horizontally in the space provided
on the top left and press open the
cover. You can then remove the
cover by hand.

health problems for the occupants.
“Improper use” of the ventilation
system by the occupant, in
combination with the high level
of insulation of modern buildings,
allows humidity and dampness to
build up.
The housing of the Titon WCME100
is constructed to allow easy
replacement of the parts, which
makes maintenance and cleaning
very simple. The Titon WCME100
contains parts that may carry
electrical current. For this reason,
you should consult a qualified
technician if you think the unit
is faulty. Repairs should always
be carried out by a qualified
technician/electrician.
The Titon WCME100 contains
rotating mechanical parts. These
parts remain in motion after the
unit is electrically isolated. Wait at
least 60 seconds after unplugging
the unit before opening.

Humidity levels within the home
can become so high that health,
damp and mould problems can
arise. A family of four can produce
between 14 and 20 litres of water
vapour per day through breathing,
sleeping, cooking, washing, using
the dishwasher, bathing, watering
plants, etc.
Also, products within the home,
such as textiles, carpets, parquet
floors, newspapers and household
chemicals contain harmful
substances (volatile organic
compounds) that can have negative
effects on health. This is why
excessive water vapour and odours
must be removed from the home
for the safety of the occupants.
Before making any modifications to
the system electrically isolate the
unit (remove fuse to ensure unit
cannot be accidentally switched
back on again). The front access
cover of the unit must only be
removed by a suitably qualified
technician/electrician.
The Titon WCME100 is modular and
has several different components.
This makes the system more
reliable technically and simpler
to service. The unit is made of
polypropylene (a type of plastic).
This material has a long life and
can be cleaned with a damp cloth.
The ventilation unit should be
inspected periodically for dust
and dirt. Before doing this, you
must make sure that the unit is
electrically isolated (remove fuse to
ensure unit cannot be accidentally
switched back on again).

3. Adjust the low level
potentiometer (‘Laagstand’)
until the required flow rates are
obtained. DO NOT adjust the high
level potentiometer, see diagram.
All adjustments must be made
within the first hour of operation.
After this time, the unit will need
to be switched off for 2 minutes
and turned back on before making
further adjustments.
This ventilation system is installed
to run continuously, even when
the house is unoccupied. The
performance of the system is
linked directly to the layout and
size of your home.
A ‘Boost’ setting may be available
in certain properties and localised
switches will enable you to utilise
this when required.
Very little energy is used when the
system is in operation, due to the
use of a direct current (DC) motor.
DO NOT switch the unit off, as this
may increase indoor pollutant
levels and damp, therefore the risk
of mould growth. This in turn could
damage the fabric of the building.
The system can only function well
if you use it sensibly and maintain
it properly.

The extractor unit ventilates the
home through extract diffusers
fitted in the kitchen, bathroom
and WC. These are connected
to the central extractor fan by
extract ducting. To ensure there
is a good distribution of fresh air,
air is extracted from those rooms
through the extractor diffusers,
while fresh air from outside enters
the home through openings (such
as window slot vents or grilles) in
the living rooms and bedrooms.
If the unit is not giving the correct
flow rates, it may be adjusted to
suit the requirements as follows:
1. Electrically isolate the unit
(remove fuse to ensure unit cannot
be accidentally switched back on
again).
2. Remove the cover by levering
the tabs at the back of the unit with
a bladed screwdriver.
