Service and Maintenance
• One of the most common causes of poor
indoor air ventilation system is that it is not
managed properly.
• Poorly maintained ventilation systems may in
it self be a problem for air quality, the air can
be worse than it had been without ventilation.
• Alignment, then the settings made when the
system is installed, is also very important for
the efficiency of the system should be fine.
• Some other common problem areas are:
• Filters are dirty giving a higher pressure drop
and thus higher energy consumption. The-
refore, the filters should be changed once
or twice a year to effectively fulfill their role.
Changing the filter is easy, about as easy as
changing tha dust bag.
• Dirt accumulated in the ventilation system
can also eventually cause the air flow to be
too low. So it is very important to keep the
ventilation system clean.
• To turn off the fan at night can cause conta-
mination spread through ductwork.
• Moisture problems may be due to poor rain
in outdoor air or condensation in the ducts
because of poor insulation or disconnected
units.
• The best thing is to never let this kind of pro-
blems arise, for as with most problems, they
are difficult to correct when they get there.
The easiest way to prevent these thing is by
managing the ventilation system as well and
regularly as you do the rest of the house.
If a plant is to be operated properly, all the
instructions for maintenance and regularly
updated.
