Maintenance
Nilan’s ventilation units last for many years, but in order to enjoy the full potential of your unit, whilst
avoiding unnecessary electricity consumption, correct maintenance is important.
The insides of the unit can be wiped with a damp cloth -
without
soaps or detergents.
The following parts require regular maintenance:
• Water trap
• Filters
Water trap
The water trap can dry out and prevent water from draining from the condensate tray, because air will
then blow into the unit. Condensate water will accumulate in the condensate tray. This will eventually
overflow and potentially cause water damage to the surface supporting the unit.
The water trap should therefore be checked regularly and filled with water, especially in the summer
when the risk of the water trap drying out is highest.
Filter replacement
The purpose of the filters is to protect the fans and the heat exchanger from dust and dirt, which may
cause damage.
For operation to run smoothly, it is important to change the filters as required. The filter timer in
Nilan’s control system is set by default to indicate that filters should be replaced after 90 days, but this
can be changed as required to 180 or 360 days.
If the filters are not changed, ventilation will lessen. This may cause the indoor climate to deteriorate
and affect the automatic humidity control system of the unit.
The exchanger
The exchanger should be checked for dust and dirt every two years to ensure that air can pass through
unhindered. A blocked exchanger will increase power consumption.
