USER GUIDE
eco EC(E) units main board (units with direct current fans)
The ventilation unit does not require any mechanical maintenance, only changing of the filters periodically and cleaning of
the heat exchanger and fans (when needed). Cut the power supply to the unit before starting any service work (from the
main switch or by removing the service hatch of the LTR-series units). Wait for two (2) minutes before starting the mainte-
nance work! Although the unit’s power supply is cut when the hatch is opened, the fans still rotate and the electrical coil
in ECE-model is still hot for a while.
Cleaning the heat exchanger
When changing the filters, check if the heat exchanger is dirty. If cleaning is required, remove it from the unit and carefully
wash through the air channels with a hand shower using a mild detergent, taking care not to get the motor wet. The heat
exchanger can also be cleaned by blowing through the air channels using compressed air. Do not use a pressure washer
and do not submerge the heat exchanger into water!! When restarting the unit after cleaning, check that the heat exchan-
ger wheel can turn freely.
Cleaning the fans
When changing filters, also check the condition of the fans. If cleaning is required the fans can be removed from the unit
and cleaned with a toothbrush or compressed air.

The heat recovery can be turned
off only when the outside air
temperature 15°C (the
value can be set on the potentiom-

Trimmers for regulating the air amount. The
regulation is proportional for the different speed
positions. I.e. the regulation -10% on speed setting
4 (100%) means the exhaust air fan runs on 100
% and the supply air fan on 90 %. Also read the
Ch. “Adjusting the proportion of supply air and
exhaust air”.
