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, bathroom, wc(s) and possibly the
utility room are extracted, while the same amount of
fresh air is blown into the living room and bedrooms.
Gaps under or near doors ensure a good through-flow
in the dwelling.
Ensure that the gaps under or near doors 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 intake 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, wc and (if
present) the utility room (E).

2.3 Reading and setting the comfort
temperature
The unit will strive for the most comfortable
supply air temperature based on the set comfort
temperature.
It is best to set the comfort temperature to the
same temperature as the room thermostat (of the
central heating system).
The comfort temperature can be set between
12°C and 28°C. How to read or set the comfort
temperature on the present operating device can be
found in the document of the operating device.

2.4 Switching the supply fan on and off
When required, the supply fan of the unit can be
turned off manually. This may be desired to keep
out unpleasant odours from outside. Bear in mind
that switching off the supply or exhaust fan will
temporarily immobilise your dwelling’s balanced
ventilation system, so do not forget to turn the
supply fan on again. How to switch the supply fan on
or off on the present operating device can be found
in the document of the operating device.
When can the supply fan not be turned off on the
display?
To prevent air being sucked back from the chimney
of a fireplace the unit is fitted with an open fire
programme. When needed the installer or service
engineer can turn this programme on. If the open fire
programme is turned on the supply fan cannot be
turned on or off manually.
When can the supply fan not be turned on?
The supply fan cannot only be operated manually
but can also be controlled automatically by the unit
itself. This occurs in the winter to protect the unit
from freezing. If the supply air is too cold for the
unit, the unit will automatically switch the supply fan
off. In this case the supply fan cannot be turned on
manually.

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 result
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 display you must clean or
replace the filters.
The following filter malfunctions appears alternately
on the display: and
The installer of the unit can provide the necessary
new filters.

15 - EN
4.1.2 Cleaning the internal filters
Vacuum the filters (B) with a vacuum cleaner instead
of replacing them with new filters.
When using the unit for the first time, it
is recommended to clean the filters (and
valves) first. During the construction phase
the ventilation system could have become
dirty with building dust.
4.2 Cleaning the valves
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 them. If a filter
is present, clean it 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 doors. For
example with furniture, draught excluders or
deep-pile carpet. The gap should be at least
10mm;
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
service engineer
Not all neccesary maintenance can be done by the
user.
Once every 2 years the installer or a service
engineer 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 display 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 malfunctions:
Action Explanation
1Note down the malfunction code that
appears on the display of the unit
2 Note down the unit type.
This is given on the identification plate on
the unit near the power supply.
3Contact the installer or service engineer 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 result in problems with
mould.
If the unit is installed in an area with a higher
average humidity (such as bathroom or
wc) 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.

EN - 16
I Commissioning & Inspection Record
This should be used to record all installation details. The Commissioning Engineer should use the following Parts
1 to 3, to record important information relating to the installation, of which, copies should be given to the Building
