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.
