INSTRUCTIONS FOR USE
2. INSTRUCTIONS FOR USE: VALLOX 70, 70 OK, AND 70 K
In order for indoor air to remain healthy, also for the structures of the building, ventilation
has to be in continuous operation. Do not stop ventilation even for longer holidays, because
that makes room air musty, and during the heating period room air humidity may condensate
in the ducts and the structures, thereby causing humidity damage.
2.1. Initial Adjustments
The unit comes in three models: VALLOX 70, VALLOX 70 OK, and VALLOX 70 K. They are
all equipped with electric post-heating. The OK model is controlled by the unit itself, and
the two other models by a cooker hood or a separate control center.
The ventilation system operates correctly when the air flows in different spaces have been
measured and adjusted through the valves according to the values planned.
After the initial
adjustment have been done, the position of the ventilation valves must not be changed
, with the
exception of the outlet valve with a knob, located in the ceiling of the sauna, that you can
adjust if needed. The initial adjustments ensure that ventilation is adequate and that
discharge air flow is always bigger than supply air flow, i.e. the house has a negative
pressure compared to outdoor air. If the house has a positive pressure compared to outdoor
air, the air of the house penetrates the building envelope and the space between the
windows, thereby possibly causing humidity damage during the heating season.
In normal conditions,
basic ventilation
is adequate, which means that air is replaced once
every two and a half hours. Increased ventilation is needed during sauna baths, cooking,
washing of clothes or family parties.
If the user does not know the air flows measured, the table below indicates approximate
discharge air flows and the total electricity consumption of the fans at different fan speeds.
The table also shows the fan speed that is adequate for normal basic ventilation in dwellings
of different sizes. The switch positions in the table, i.e. the shaded fan speeds, are factory-
set values. If needed, an expert or an electrician can change the settings and choose the
speeds shown in the white columns. Speed changes are always made by an expert, not the
user himself. The room height is 2.5 metres.
Remember!
