2. Fans check (once per year). Polluted fans decrease efficiency.
Before performing any inspection work, check whether the unit is switched
off from the electric power supply.
Fans should be carefully cleaned with textile or soft brush. Do not use water. Do not break balance. Check if
fan freely rotates and is not mechanically damaged, if impeller does not touch suction nozzles, fan does not
spread noise and mounting bolts are screwed.
3. Air heater check. Check if electric air heater is properly fixed, wires connections are not damaged and heat-
ing elements are not bent. Check the plates of water air heater. The air heater is cleaned with hoover from
supply air side or with air blast from exhaust air side. If it is very dirty, wash with tepid water, which will not
make corrosion of aluminium. Check if position of return water temperature sensor is right. They can be dam-
aged or bent due to uneven heat or uneven and turbulent air direction. Check if electric air heater is clear of
unnecessary things and heating elements are not clogged, because this can cause unpleasant smell or in the
worst case – dust can start burning. Air flow through the air heater should be greater than 1,5 m/s. Heating
elements can be cleaned with hoover or wet textile.
4. Air filter clogging check. Change air filters when air filter clogging is indicated. We recommend to change
filters at least twice per year: before and after heating season, or more
recommend cleaning them. Stop the air handling unit before changing filters.
Clogged filters unbalance ventilation system, air handling unit uses more power.
