Generally 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 may escape through the filters and potentially mix with moisture from the extract air. WARNING Stop the ventilation unit on the control panel and switch off the power supply for the ventilation unit before you open the front door to the unit.
Check air intake and discharge It is important for operation of the unit that air can freely move through the air intake and discharge. If roof stacks have been fitted to the air intake and discharge, check that they are not blocked with birds' nests, leaves or other dirt which can hamper air passage.
User settings Setting the ventilation unit Turn off the ventilation unit If you need to open the doors to the ventilation unit in connection with servicing or filter replacement, remember to turn off the venti- lation unit. You do this under the menu item “Operation”. When the ventilation unit is off, this icon is displayed on the main screen of the control panel in the top righthand corner.

Supply air heating You will only have this menu item if an after-heating element has been installed and it has been activated in “Service settings”. ATTENTION An after-heating element is not included as standard. However, you can order it as an additional extra, and it can also be retrofitted.
After-heating element You will only have this menu item if an electrical after-heating element or a water after-heating element has been installed, and if it has been activated in “Service settings”. ATTENTION An after-heating element is not included as standard. However, you can order it as an additional extra, and it can also be retrofitted.
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.
Filter alarm 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.
