Quick Guide to Spirit K2
Air Handling Unit
System description
The unit provides ventilation in the home.
It supplies
fresh air
to living rooms and bedrooms via valves, which are normally
located in the ceiling. At the same time
used air
is extracted from the kitchen,
bathroom, toilet and laundry room.
The unit contains a rotating heat exchanger that recovers around
80% of the heat in the extract air and transfers it to the supply air
when needed.
The unit is operated from a separate control panel.
Operation
Fan speed
The fan speed has to be adjusted to the need
for ventilation. See "consequences of incorrect
operation".
Min
Must not be used in the first year
of operation or when the home is
in use
Normal
Normal operation
Max
Used for raised humidity levels, e.g.
when the bathroom is in use, and
generally when there is an increased
need for ventilation
If a lot of moisture is generated, it is important to
use
Max
for a while afterwards to give the system
time to extract the moisture from the room.
CI60
The fan speed is
adjusted using the
+
and
–
buttons on the
panel.

Consequences of incorrect operation
Condensation
A lot of moisture is often generated in wet rooms as a result of drying clothes, showering,
etc. If the outdoor air is cold, it will cool the walls down and the moisture in the indoor air
could condense on the unit.
If you experience this, you must increase ventilation to Max when a lot of moisture
is being generated.
Increased ventilation will ensure that the humid air is extracted from
the room and replaced with drier air.
Filters
Old and blocked filters provide poor ventilation and can also cause condensation
problems.
New homes
New homes give off large quantities of moisture and gases from textiles, building mate-
rials, paint, etc. This is known as
off-gassing
and can cause discolouration of walls and
surfaces in the home. Ventilation is therefore very important!
