USING VENTILATION UNIT
Once the ventilation system is carefully designed and
installed, user actions are not required. The user can relax
and enjoy good ventilation.
General instructions
• Ventilation must be sucient.
If ventilation is not sucient, the indoor air humidity will
rise, which can cause condensation on cold surfaces.
• The indoor air humidity levels must be checked at
regular intervals.
The recommended relative room air humidity is
40–45% at most (with room temperature at 20–22°C).
By adhering to these values, the indoor air humidity
remains at a healthy level and the risk of condensation
lowers signicantly. Humidity can be measured with a
hygrometer. When air humidity rises over 45%, ventilation
must be boosted. When air humidity drops under 40%,
ventilation can usually be reduced.
• The cleanliness of lters must be checked regularly.
In winter, the exhaust air lter collects dirt faster than the
replacement air lter. This means that the replacement
air ow is reduced, which can lead to a rise in indoor air
humidity, which in turn weakens the eciency of heat
recovery.
If you encounter issues with using the ventilation
unit, check for answers in the Troubleshooting
table at the end of this manual.
Always keep the panel in the wall mount.
Do not shut down the ventilation unit. The
ventilation unit must always be kept in operation
at the power level set by the ventilation system
designer.

Do not try to set the system settings by yourself!
Installing a ventilation system is a job for a trained
installer.
Do not damage the control panel screen with a
sharp or scratching object.
WARNING
WARNING
More information about cleaning and changing the lters
is in the Maintenance section.
• Check monthly that the heat exchanger is functioning
correctly, i.e. rotating.
• More information on the checking and cleaning the
heat exchanger is in the Maintenance section.
• If ventilation unit is not used for a long time, it can
be shut down as long as the fresh air intake vent and
exhaust air blowout vent are covered.
This prevents humidity from condensing on the electric
motors of blower, for example.
• In the autumn, before the beginning of heating
period and before beginning cooling (if the unit has
a cooling function), the condensation water sewage
functionalities must be checked by pouring water in
the condensation water sewer and making sure that
the water drains away.
This instruction is for the users of the Enervent ventilation
unit and control panel.
Be patient! The control panel takes some time to react.
