3. Air heater check.
Check if electric air heater is properly fixed, wires connections are not damaged and heating
elements are not bent. They can be damaged 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
1
.
Filters are one time used. We do not recommend cleaning them. Stop the air handling unit before changing
filters.
