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
results 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 ComfoSense or CC Luxe**
you must clean or replace the filters.
The installer o f the unit can provide the necessary
new filters.
