MAINTENANCE OF TALTERI
For producing good indoor climate continuously, the air exchange systems require regular maintenance.
The metallic grease filter of stove hood must always be kept clean for fire safety reasons. Cleansing with hot
water or dishwasher once a month is necessary. Substances suitable for machine washing may darken the
aluminium parts of the filter.
The inlet and outlet filters of Talteri must be cleansed at least twice a year.
In summertime the summer cassette plate will be set to summer mode
when the external air should come in
fresh and clean.
The heat recovery cell 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 heat
recovery cell back to its place.
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.
The impellers, air exchange adjusters and thermostats are components that do not require regular
maintenance. Electrical works can be carried out only by a qualified electrician.
During the frosty period the heat recovery cell is defrozen by using the preheater. The power of the
preheater is mainly adequate to keep the heat recovery cell defrozen.
In extreme conditions, if the power of
the preheater is not sufficient, the supply fan power will be reduced or stopped by the freezing protection
thermostat when the exhaust air temperature drops below the set value (0°C). The supply fan starts when
the exhaust air temperature rises above the set value.
Under extreme conditions (humidity /harsh cold) the HR-element may freeze over and the anti-freeze
protection defreezing cycles 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 afterheating. The functionality
can be proved by comparing the temperature of inlet air to the set value of the inlet air afterheating.
The overheat protection has been activated in case the 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.
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.
