General; Guarantee And Liability; Operating Principles - Zehnder ComfoCool Manual Del Usuario

1. General

Congratulations! Your dwelling has been fitted
with a Zehnder comfort-unit equipped ventilation
system. This system has been installed in order
to provide your house with fresh air at a pleasant
temperature.
For optimum user comfort, it is essential to under-
stand how the system works and how to operate
it. Please therefore read this manual carefully.
ComfoCool
In combination with a ComfoAir heat-recovery
unit, the ComfoCool is designed to regulate to
comfortable levels the temperature and humidity
of the fresh air supplied to your dwelling. This cre-
ates a comfortable and pleasant indoor climate.
The ComfoCool works differently to an air condi-
tioner:
• An air conditioner recirculates air present in
your dwelling but does not help to ventilate
it. The ComfoCool supplies outdoor air and
is integral to the ventilation system.
• An air conditioner only works in the room in
which it is located. The ComfoCool cools air
throughout the dwelling.
Zehnder wishes you
the highest level of comfort in your home with
What is ventilation?
Did you know that we spend at least 70% of our
time between 4 walls? That may seem a lot, but
think about it: during the day we work indoors, in
the evening we live indoors and at night we sleep
between 4 walls. So, most of the time, our lives are
spent indoors. There is nothing wrong with being
indoors, but we need to ventilate well. Breathing
generates CO
2
(caused by perspiration, cooking and showering)
inside the house not only causes condensation,
mould and odours, but also increases the risk of
health problems due to reduced air quality (higher
CO concentrations). So in order to improve the
2
air in your house, you must ventilate. Opening
a window for ten minutes only has a short-term
effect. As soon as you close it, the fresh outside
air disappears. It is therefore vital to ventilate 24
hours a day.

For further information please refer to the fitting
instructions.
If you suspect a defect, please observe the fol-
lowing safety precautions:
1. Never open the unit. Repairs should only be
carried out by a recognized fitter.
2. The ComfoCool contains coolant (R134a).
This coolant is colourless, non-toxic and
non-flammable. The volume of coolant in the
ComfoCool is so small that it cannot possi-
bly lead to hazardous concentrations in your
dwelling. The unit has been designed to pre-
vent coolant from leaking under normal op-
erating conditions.
If you detect a faint, ether-like smell:
• Do not touch the unit for at least one hour;
• Open windows and doors in the room in
which the unit is located for at least an hour;
• Contact your installer.
