For producing good indoor climate continuously, the
air exchange systems require regular maintenance.
The metallic grease filter of stove hood must be
kept clean at all times for fire safety reasons.
Cleansing with hot water or in a dishwasher once a
month is absolutely unavoidable. Substances
suitable for machine washing may darken the
aluminium parts of the filter.
Filter bags of fresh and extract air have to be
regularly pulled out and replaced if needed. The
pollen filter should be changed every summer.
When installing the filters, it should be checked
that they are in place and
springs to the silicon sealing to avoid a bypass flow.
The summer cassette plate will be set to summer
mode when the external air should come in fresh
and clean.
NO SUCTION BY OUTLET AIR IMPELLERS AND / OR
INLET AIR IMPELLERS DO NOT BLOW AIR.

LTO-exhanger will be pulled out of the unit and
washed thoroughly in autumn just before the heating
season begins - the heat recovery will then be at its
best.
Check the condition of sealing and push the
transmission back to its place.
The noise deductors above the impellers can also be
detached for washing if necessary.
The inner painted walls of the unit are easy to clean.
Check the condition of sealing, clean the outlet hose
of condensing water and make sure the water flows
freely and without any obstructions.

by a qualified electrician.
CHECKING THE FUNCTIONING OF OUTLET AND INLET
IMPELLERS
Stop the machine, open the door fastened with four star dogs.
In winter, you should let the machine to cool for a moment.
Use the machine on slow speeds, state the speed changes.
DO NOT TOUCH THE IMPELLER WINGS WHEN THEY ARE
MOVING !!
The performance of inlet impeller is decreased or stopped
by the freeze-alert thermostat when the temperature of the
exhaust air reduces below set value (5c).
The inlet impeller starts again when the temperature of
the exhaust air rises above the set value.
The channels must be checked if the impeller works
but the air exchange is inadequate or the temperature
changes in the channels between the interior and the machine.
Temperature changes and humidity concentration in
channels must be prevented by improving the isolation.
During harsh frosts in winter, the equipment must
be used on lower speed so the post-heating will last and there
will be no draught. Under extreme conditions (humidity /
harsh cold) the Ito-element may freeze over and the
anti-freeze protection series are not able to defrost it. If
such a case occurs, the machine has to be stopped, opened
and the cold flow stopped and the ice given the necessary
time to melt. Check the drainage of condensing water!
In case the water-lock dries out and makes pulping noise, you
can
pour a drop or two of cooking oil.
In really cold weather, the head recovery unit heats the
preheated inlet air with post-heating. The functionality can be
proved by comparing the temperature of inlet air to the
set value of the inlet air post-heating.
heating of resistance can also be stated by careful checking
from the open machine running on slow speed.
The overheat protection has been activated in case
the barrier temperature has risen +90 C (for instance, in case
of power failure). Reset the overheat temperature by pressing
the switch under the threaded contact protection.
Ask a qualified electrician to check the wiring.
