Safety
Important information
Power supply
CAUTION
Always disconnect the power supply to the unit if an error occurs that cannot be rectified via
the control panel.
CAUTION
If an error occurs on electrically conductive parts of the unit, always contact an authorised
electrician to rectify the error.
CAUTION
Always disconnect the power supply to the unit before opening the unit doors, for instance for
installation, inspection, cleaning and filter change.
Heat pump domestic hot water
CAUTION
Avoid direct contact with the heating system pipes in the heat pump as they can get very hot.
CAUTION
To protect the heat pump against damage, it is fitted with the following safety equipment:
• Electronic temperature monitoring
The heat pump must undergo suitable service inspections under applicable legislation and regulations
to keep it in good condition and in compliance with safety and environmental requirements.
Responsibility for maintenance of the heat pump rests with the owner/user.
Disposal
Ventilation unit
Nilan’s units consist mainly of recyclable materials. They must, therefore, not be
mixed with household waste, but must be delivered to your local recycling center
for disposal.
Heatpump
Concerning disposal of units with heat pumps, it is important to contact the local
authorities for information about correct handling of these. The heatpump
contains the refrigerant R134a, which is harmful to the environment if not
handled correctly.

Quickguide
Safety switch
Emergency stop ventilation
If the ventilation has been stopped for a lengthy period, condensation will occur in the duct system.
This occurs when the warm air in the dwelling penetrates into the cool ducts. This presents the risk that
the water will drip out of the ceiling valves, damaging floors and furniture.
To avoid this, the user is not directly permitted to turn off the ventilation. However in emergency
situations, where the user is asked to go indoors, close windows and doors and turn off ventilation
systems, this must still be possible.
The user may then press the emergency stop in the settings menu:
A warning will appear before the ventilation can be turned off:
Warning: Are you sure you wish to turn off the ventilation?
If the ventilation is not running, you may get problems with high air humidity and condensation in the
ventilation ducts, and a risk that your home may be damaged.
You are only turning off the ventilation. Domestic hot water will be heated by the supplementary
electric heating, if activated.
1. Press the settings icon. 2. Press "Emergency stop ventilation".
3. A warning will appear, but press yes. 4. A red line through the ventilation icon will appear on the display,
indicating that the ventilation has been turned off .
5. When the danger has passed and the ventilation can be used again, press
"Emergency Stop Ventilation" once more. 6. Press "Turn on ventilation again".

the wanted room temperature by touching the red or blue arrow.
2. By touching the current hot water temperature, the wanted hot water temperature is shown. You
can change the temperature in the domestic hot water tank by touching the red or blue arrow.
3. The number of dark segments shows at which ventilation level you want the unit to run. There are
four levels and the level is changed by touching the icon.
If the unit or functions are turned off, a red line will cross the functions, which are off.
