General information A ventilation unit from Nilan can last for many years if it is properly serviced and maintained. Ventilation units are often hidden away, and they are therefore rarely given attention in everyday life. But just as you maintain your car, your ventilation unit will need servic- ing regularly to keep it functioning properly.

Annual maintenance General cleaning The ventilation unit should be cleaned on the inside once a year. Dust can slip through the filters and mix with dampness from the ex- tract air. WARNING Stop the ventilation unit on the control panel and switch off the power supply for the unit before opening its front door. You may want to remove dust with a vacuum cleaner before wiping the ventilation unit inside.
User settings Ventilations settings Turn off the ventilation unit If it is necessary to open the doors while servicing the ventilation unit, for instance when changing filters, the unit must be turned off. This is done under the menu Operation. When the unit is turned off, this icon appears on the main screen.

Week program You can program the ventilation unit to run in accordance with specific settings at fixed times during the week via a week program. On the main screen in the top right side an icon will be displayed when the week program is active >...
Air humidity The primary purpose of ventilation is to extract humidity from the house so it does not damage the building, and to achieve a good in- door climate. During long periods with sub-zero temperatures, air humidity in the house may fall to a level that is critical for the build- ing and for the indoor climate.
Control This menu is only displayed if a CO -sensor has been installed, and the function has been chosen under Service settings. ATTENTION A CO sensor is not a standard part of all ventilation units, but may be purchased as an accessory. If the number of people using a building varies considerably, controlling ventilation through the CO level in the extract air may be a good solution.
Air filter ATTENTION It is important to change the filters regularly and when needed. Dirty filters reduce the efficiency of the ventilation unit and result in a poorer indoor climate and higher power consumption. From factory, the filter alarm has been set to signal filter replacement every 90 days. You can set the timer to fit the level of pollution in the area where the ventilation unit has been installed.
Temperature control If you have not installed an after-heating element, use the settings to control the bypass damper. It is necessary to install an after-heating element if you want to control the supply air temperature and for it to contribute towards the heating of the dwelling.
