1 Introduction and safety
The unit is a balanced ventilation system with heat
recovery in order to create energy-efficient ventilation
in houses. Balanced ventilation means that pollutants
from the kitchen, the bathroom, the toilet(s) and
possibly the storage room are extracted, while the
same amount of fresh air is blown into the living room
and bedrooms. Gaps under or near the doors ensure
a good through-flow in the dwelling.
Ensure that the gaps under or near the door are
never obstructed. For example by furniture,
draught excluders or deep-pile carpet.
A balanced ventilation system consists of:
The unit (A);
Duct system for the supply of outdoor air (B);
Duct system for the exhaust of indoor air (C);
Supply valves in the living room and bedrooms (D);
Exhaust valves in the kitchen, bathroom, the toilet
and (if present) the storage room (E).
Safety instructions
Always follow the safety regulations, warnings,
comments and instructions given in this document.
Personal injury or damage to the unit can arise from
non-compliance with the safety regulations, warnings,
comments and instructions in this document.
It is recommended to take out a maintenance
contract so that the device is checked on a regular
basis. The supplier can provide a list of registered
installers nearby;
The unit may only be installed, connected,
rendered operational and maintained by an
appropriately approved installer, unless otherwise
indicated in this document;
Store the document for the entire working life of
the unit;
Instructions with regard to cleaning or replacing
the filters must be carefully observed;
When carrying out any work on the unit, make
sure the power is disconnected and cannot be
inadvertently reconnected;
The unit cannot be opened without
using tools.

Warranty conditions
The unit is covered by a manufacturer’s warranty for
a period of 24 months after fitting up to a maximum
of 30 months after the date of manufacture. Warranty
claims may only be submitted for material faults and/
or construction faults arising during the warranty
period. In the case of a warranty claim, the unit
must not be dismantled without written permission
from the manufacturer. Spare parts are only covered
by the warranty, if they were supplied by the
manufacturer and have been installed by an
approved installer.
The warranty becomes invalid if:
The guarantee period has elapsed;
The device is used without filters;
Parts are used that have not been supplied by the
manufacturer;
Non-authorised changes or modifications have
been made to the unit.
Installation has not been carried out
according to the applicable regulations;
The defects are due to incorrect connection,
inexpert use, or contamination of the system;
On-site (dis)assembly costs are not covered by the
terms of the warranty. This also applies to normal
wear and tear. Zehnder retains the right to change
the construction and/or configuration of its products
at any time without being obliged to alter previously
delivered products.
Liability
The unit has been designed and manufactured for
use in balanced ventilation systems incorporating
Zehnder heat recovery systems. Any other
application is seen as inappropriate use and can
result in damage to the unit or personal injury, for
which the manufacturer cannot be held liable. The
manufacturer is not liable for any damage originating
from:
Non-compliance with the safety, operating and
maintenance instructions in this document;
The use of components not supplied or
recommended by the manufacturer.
Responsibility for the use of such
components lies entirely with the installer;
Normal wear and tear.
End of useful life
Consult with the supplier about what should be
done with the unit at the end of its useful life. If
the unit cannot be returned to the supplier, avoid
disposing of it with the domestic waste, and ask
your local council about the options for recycling

wireless (RF) switches with the normal waste, but
bring them to the specially designated disposal
locations.

4 Maintenance
Failure to carry out (periodic) maintenance on
the unit ultimately compromises the performance
of the ventilation system.
The unit should be inspected and cleaned every 2
years by a specialist. To ensure a hassle free lifespan
for your unit, we recommend you take out a service
agreement with an expert company.
Ensure the unit has been disconnected
from mains power before carrying out any
maintenance work.
The power to the unit should not be disconnected
unless the unit is to be taken out of service due to a
serious malfunction, or for filter replacement or any
other compelling reasons.
If the power to the unit is disconnected,
mechanical ventilation of the dwelling will cease.
This can lead to a build-up of moisture and
results in problems with mould.
4.1 Cleaning or replacing the filters
Replace the filters (at least) every six months and
clean the filters every 2 or 3 months.
When indicated on the ComfoSense or CC Luxe**
you must clean or replace the filters.
The installer o f the unit can provide the necessary
new filters.

When using the unit for the first time, it
is recommended to replace the filters
(and clean the valves) first. During the
construction phase the ventilation system
could have become dirty with building
dust.

the ventilation system could have become
dirty with building dust.
4.1.3 Replacing or cleaning the external
filter
4.1.3 Replacing or cleaning the external
If so indicated on the ComfoSense or CC Luxe** you
must clean or replace the filter as is mentioned in the
external filter document.
4.2 Cleaning the valve
Clean the valves (at least) twice a year.
1. Mark the setting of the valve;
2. Remove the valve from the wall or ceiling;
3. Clean the valve in a solution of soap and warm
water;
4. Rinse the valve thoroughly and wipe dry;
5. Place the valve back WITH EXACTLY THE SAME
SETTING (and IN THE SAME HOLE);
6. Repeat this procedure for the other valves.
Some valves have a filter behind it. If a filter
is present clean this in the same way as the
valve.
About the valve settings
The ventilation air is supplied and discharged
by means of valves. Gaps under or near doors
in the dwelling ensure that the air flows in the
right direction. In order to ensure that the correct
ventilation volumes are maintained in the rooms, the
following must be observed:
Do not seal the gaps under or near the doors. For
example by furniture, draught excluders or deep-
pile carpet. The gap should be at least 2cm;
Do not change the settings of the valves;
Do not replace the valves with one another.
The installer will have set all the valves to ensure
the optimum performance of the ventilation system.
Therefore, do not change the setting of the valves.
4.3 Condensation drain
Ensure that the water seal (u-bend) connected to the
domestic waste-water system is always full of water.
4.4 Maintenance by the installer or
maintenance mechanic
Not all neccesary maintenance can be done by
the user.
Once every 2 years the installer or a maintenance
mechanic should come by for the maintenance
inside the balanced ventilation system.
Some installers offer a full maintenance contract
package where the user maintenance can also be
integrated.
5 Malfunctions
In the event of a malfunction, the corresponding
malfunction code will be displayed on the
ComfoSense or CC Luxe** of the unit.
In event of a filter malfunction the filter must be
cleaned or replaced as described in the Maintenance
chapter.
In the event of all other malfunction:
Action Explanation
1Note down the malfunction code that
appears on the ComfoSense or CC Luxe**
of the unit.
2Note down the unit type.
This is given on the identification plate on
the unit near the power supply.
3Contact the installer or maintenance
mechanic
and give him the noted information.
The system should not be disconnected from the
power supply, unless the unit must be taken out of
service due to a serious malfunction, or for filter
cleaning/replacement or any other compelling
reasons.
If the unit is disconnected from the power
supply, mechanical ventilation of the
dwelling will cease. This can lead to a build-
up of moisture and results in problems with
mould.
I f the unit is installed in an area with a higher
average humidity (such as bathroom or
toilet) the probability of condensation on the
outside of the unit is high. This is similar to
condensation on a window and no action is
needed.
